Not long ago, a reader wrote to us about a problem he is having with worms and his lawn. More specifically, he thinks that the worms in his lawn are causing it be uneven and rough, and as a result he is wondering what kind of worms he is dealing with and how he can get rid of them. One’s lawn is a precious thing, so we understand his dilemma.
A very nice and enthusiastic reader wrote to us recently about earthworms that live in the soil of Omaha, Nebraska. The reader was able to find plenty of information about worms that are used for composting (which are typically red worms, commonly called red wiggler worms), but couldn’t seem to find much on plain old earthworms that you find in soil. Allow us to be of assistance.
The annelids are a large phylum of segmented worms; consequently, annelids are commonly called simply “segmented worms.” (They are also, by the way, called “ringed worms,” as the worms’ segmented bodies often make them look like they are wrapped in small rings.) There are over 17,000 species in the annelid phylum, according to recent research, and while this is far less diverse than the phylum Nematoda, which is estimated to have approximately 1,000,000 species, the annelids are still extremely diverse relative to other species of animals.
A reader recently wrote to us inquiring about the evolution of worms. He asked several specific questions about the evolutionary history of worms, not all of which we can answer, but we can sketch a picture, even if incompletely, of the evolution of worms.
If you saw a sign that said “worms for sale,” you might think you stumbled into an alternate reality. Worms for sale? How could that be? Who on earth would actually want to buy worms? Even if an advertisement promised “cheap worms for sale” or even “free worms,” you still may think it would be crazy to take someone up on this offer.
Red worms are epigeic or detritivorous earthworms. They do not eat animal or human flesh. Red worms are vegetarians, so they eat vegetables and other organic matter. There are more than 120,000 species of flies around the world and many of the most common flies, such as the fruit fly, eat decaying fruits and vegetables as well.
Worms can survive in temperatures ranging from 50-70 degrees Fahrenheit, but the environment must still be moist and dark. When it is cold or dry, worms are not active.
If you noticed that the earthworms in your soil seem to be disappearing, chances are they are not getting the things they need to survive or their habitat has been disturbed. Without earthworm’s survival, sadly, all of earth’s plants and trees would suffer.
Caterpillars have multiple legs which enable them to crawl and climb like no other climbing herbivore on the planet. Worm movements are peristaltic, meaning, they move about through muscle contractions. Caterpillars use passive grip to tackle the most complex objects, bending, twisting, and crumpling their way up, down, and around these objects.
When the temperature of the soil reaches around 50 degrees Fahrenheit, the worms will make their way back to the upper parts of soil and any eggs will hatch.
Without earthworms, your precious pecan tree, milkwood tree or apple tree could not survive. Earthworms play an important role in helping the earth’s trees, plants, fruits, and vegetables thrive.
It is rare to come across a worm that stings outside of tropical regions, but if you do, chances are it is a bristle worm. Bristle worms may release “poison” when it stings, but the poison is not harmful to humans, only other very small animals.
When earthworms mate, they cover themselves with sticky mucus. The sperm fertilizes the eggs. Once this occurs, a ring of slime forms around the worms’ bodies.
Other methods involve using a garden fork to create vibrations and sprinkling the tops of soil with water to trick the worms into believing it is raining. Rain causes earthworms to flee to the surface for fear of “drowning” beneath the top layers of soil.
Earthworm species such as P. corethrurus have low oxygen consumption, meaning, they can survive at lower concentrations of oxygen due to low consumption. This enables P. corethrusus to survive for a very long time when soil is saturated with water.
The Adventures of Herman the Worm covers several areas. The website and CD teach students about the history of the worm, the worms family tree, worm anatomy, how and where worms live, what worms eat, why worms are extremely important to the planet, and worm facts.
In all, there are around 500 species of leeches living on the planet today, but only 63 can be found in North America and 35 in Ontario.
Bristle worms can be found in other parts of the world as well. Some are errant, meaning, they move along the shoreline and shallow water, while others are tube-binding which means they build a permanent tube or home along the shoreline flats.
Although caterpillars and worms have some similarities, many differences exist between the two species. Worms and caterpillars have soft bodies, meaning they do not have a skeletal system, and both animals are nocturnal.
Worms and caterpillars are not the only worm-like creatures that have differences. Some people are quick to confuse millipedes and centipedes with worms. The obvious differences between these creatures is the fast movement of these leggy creatures and the thousands of tiny legs attached to the body.
At last count, there were more than 9,000 species of segmented worms on the planet today. Some of the most common types of segmented worms include earthworms, leeches, and sandworms.
Silk worms are often confused for worms, but they are not a member of the worm family at all. Instead, they are caterpillars that create a cocoon to complete the transformation process from caterpillar to butterfly.
Depending on the type of worm, all kinds of plants may be consumed. They eat leaves, dead grass, fruit, vegetables, and all kinds of flowers. These materials contain organisms that provide a steady diet of bacteria, algae, and fungi.
This means, the Gippsland rarely leaves its wet underground labyrinth. According to the Museum of Victoria, it is only found in the Bass River Valley of South Gippsland, in an area of about 100,000 hectares bounded by the towns of Loch, Korumburra and Warragul.
To find out what kind of insect has been gnawing away at your flowers at night, you have to catch them in the act first, then identify them. Once you have identified the culprit, you can explore control options.
To learn exactly what type of worm is living in your cherry tree you will need to collect specific information on the appearance and behavior of the animal in question. Once you have this information, you can go online to find out the specific type of worm or visit your local library or bookstore to find books on worms
You should not handle cocoons if you do not want to disturb this crucial stage in the life cycle of insects. Unfortunately, in this stage the insect is mostly defenseless.
Much like worms, caterpillars also spit juices and produce bad smells to ward off attackers. Caterpillars also have the ability to create a silk line and drop out of site if a predator approaches.
suction motion aids in helping the worm consume large amounts of food in a short amount of time. The gizzard grinds the food. Worms eat so much that they typically produce excrement equal to their own weight every 24 hours.
Worms’ bodies produce a sticky film (mucus) helps keep it from drying out. Worms breathe through their skin.
There are so many things to learn about when it comes to worms such as anatomy, where they live, reproduction, and eating habits. As a result, the amount of material that can be used for worm lesson plans is virtually endless.
Most gardeners, nature lovers, and others take joy in observing monarch caterpillars as they transform into butterflies, and flutter around gardens and trees. Worms, earthworms in particular, may not be as beautiful as monarch caterpillars, but they are crucial to maintaining beauty in our environment as well.
In addition to recognizing signs of worms in dogs, it is important to recognize what the different types dog worms look like. Round worms look like spaghetti and tapeworm segments look like grains of rice.
Worms and caterpillars have strong appetites. Worms eat so much that they typically produce excrement equal to their own weight every 24 hours. Some caterpillars have earned the name “pest” because in high enough numbers they can eat through entire fields of plants and flowers, killing the plants in the process.
Earthworm species such as A. gracilis have high oxygen consumption, meaning, it has greater oxygen consumption, therefore it is more sensitive to depletion of oxygen when the ground is saturated with water.
Green caterpillars are very common and can easily be confused with worms in the early stages of the lifecycle. They thrive in many environments including gardens, trees and plants. Caterpillars are often found on the stems of plants and trees as this is a common form of food.
Many moth species are better known as caterpillars because of the damage they can inflict to fruit trees and other produce. There are over 180,000 types of caterpillars throughout the world.
The earthworm is by far the most vast and varied group of segmented worms on the planet. Just think, there are more than 2,700 different types of earthworm living in every corner of the earth today.
Whether they live in the cool damp soil or on a white sand beach, most worms belong to the segmented worms group. There are more than 9,000 species of segmented worms in existence today.
Worms eat more than just plants. They eat dead grass and dirt too! Leaves and dead grass contain organisms that provide a steady diet of bacteria, algae, and fungi. Worms also eat fruits, and antioxidant rich vegetables.
In general, worms and caterpillars move slowly, but when either creature senses danger or a predator, they move quickly.
One of the most obvious differences between caterpillars and worms is caterpillars move around on three pairs of legs, while worms have no limbs at all. Worms move around by contracting their segments.
Earthworms have light-sensitive cells located throughout the outer layer of the skin. Earthworms cannot use these cells to see, but they help worms detect light and changes in light intensity. These light-sensitive cells are also sensitive to touch and chemicals.
Depending on the environmental conditions, certain earthworm species may live anywhere from 4-8 years. The life span of an earthworm also depends on the number of predators the worm has to fend off each day.
Earthworms don’t actually bite, but their skin can cause major irritation on human skin if contact last more than a few minutes. The irritation is not a result of the actual worm skin but rather the materials that worms pick up as they writhe, wriggle, and borough inside the earth and along the ground.
The speed at which earthworms travel depends on the size of the earthworm. A small earthworm travels at a rate of around 27 feet per hour (0.2 centimeters per second).
While leeches are not known to transmit disease, they can cause irritation and other allergic reactions in hosts as well as an infection or blood poisoning. In addition, a leech bite can bleed for hours if not treated. First, you must remove the leech by pushing the leech off the skin from the skinny end.
There are a number of rules to follow when feeding compost worms. It is important to avoid feeding bones, meat, fat, cheese or dairy, grass, twigs or wood, banana peels, or any synthetic materials to your red worms.
Marine worms come in a variety of shapes and sizes. They may be long and thin, plumb and short, flattened and floppy, bright and colorful or dull and dark.
When the worm eats its food, it pulls the materials into its mouth with the help of the pharynx and its prostomium, also called “acron”.
If you plan to find your own worms, then you should examine the soil and the worms for grubs. Simply sift through the worms and soil to look for larvae.
While worms need moisture to survive, too much moisture can be fatal. If too much water is present, it takes the place of oxygen, which will cause the worms to flee to the surface.
The mealy worm is the larva of the mealworm beetle, which is a species of the darkling beetle. Because of their high protein content, mealy worms are mostly used as a food source, but they can also be used for composting.
The earthworm’s moist, sustenance rich environment plays an extremely important role in reproduction as well. Worms prefer to mate and reproduce in warm moist soil, away from the light. If the conditions are not suitable for reproduction, the worms won’t reproduce.
Grub worms feed on plants and the roots of turf grasses and the adult beetles feed on trees, shrubs, and other foliage. While grub worms are harmless to humans, they can be devastating to crops mainly because they feed on crop roots.
Much like earthworms, peanut worms prefer to live in moist, dark places. Many peanut worms burrow themselves under rocks and boulders that can be found in the mud or sand or they make their home in reef.
A professional home and garden exterminator will know exactly how to kill the pests in your pecan trees without killing the earthworms below.
Inchworms may be small, but they have a voracious appetite for healthy foods like fruits and vegetables. Depending on the type of inchworm, these greedy little creatures will nosh their way through crops until there’s nothing left!
There are literally thousands of different types of worms on the earth. Some can be found in just about any garden or backyard, while others may be found buried beneath the sand on hundreds of beaches overseas.
The flat worm is usually medium-brown in color with dark markings or stripes. Some worms may appear gray to greenish/gray as well. All types feed on earthworms, so beware.
Not all worms thrive under identical conditions, so its best to stick to one type of worm. It is also good to stick to one type of worm if you are interested in maintaining a small scale “worm farm.”
The limb boring worm tunnels into hard materials such as rocks and shells. While you may never witness a boring worm in action, you may notice their bodies sticking out of mollusk shells and rock cracks after they have tunneled through.
To help answer the question, “what kind of worm is this?” an entire branch of zoology called “Entomology” was established to classify the thousands of worm species that have been discovered on planet earth.
Large bristle worms are usually gray or brownish in color. Some are also salmon pink with white setae around the body. Like most worms, bristle worms are nocturnal, so they are not usually around during the day.
There are three broad ecological groups that have been identified for earthworms including: epigeic, endogeic, and anecic. The groups are based on what the earthworms eat and where they tend to live in the soil.
Worms called gastrotrichs have bodies covered with tiny tubes that secrete a cement. The cement tubes make it appear as though the worm is carrying a case filled with sand!
Killing worms in pecan trees can be tricky as many chemicals and pesticides that are meant to kill pests can actually kill the beneficial earthworms living in the soil below.
Bacillus thuringiensis, a wilt pathogen, is available to gardeners to help control worm infestations. Fortunately, this pathogen is only toxic to insects.
When raising earth worms, you won’t have to “turn” your worm system. When composting, it is essential to turn your worm system to encourage aeration.
Worms eat so much that they typically produce excrement equal to their own weight every 24 hours.
Garden worms come in all shapes and sizes and believe it or not, they play a major role in the survival of our fruits, vegetables, trees, and plants. There are so many worms living inside the earth that it would be impossible to list them all here. Fortunately, there are some worm groups that are larger than others.
When worms create worm holes, this activity aerates and mixes the soil and it is constructive to mineralization and nutrient uptake by vegetation. This is crucial to the health of the earth and soil for gardening and farming.
Because the silk worm is so precious, it is no longer found in nature. In fact, the silk worm is totally dependent on humans for reproduction.
Earth worms belong to one of several different types of ecological groups. There are three broad ecological groups that have been identified for earth worms including: epigeic, endogeic, and anecic.
Rarely will you find a lone worm writhing around in the soil with no other worms to be found. Worms must live in the soil, but not just any soil. Due to certain ideal conditions, large numbers of worms will gravitate towards certain areas. This means that you will find worms living in large groups, [...]
If you attempt to chop up a hammerhead flatworm or even smash it, the pieces will only regenerate into new hammerhead flatworms.
Bristle worms belong to the family Polychaete. The common name is Acropora Crab. Bristle worms are usually found under rocks and corals in a number of different tropical areas throughout the world.
Worms can be found at just about every corner of the earth. They live in trees, in bark, and under rocks as well as along rivers and near springs, and ponds. Their favorite place to live, however, is in the earth’s rich soil.
Little boys love them, little girls think they’re gross, and adults think they’re pretty creepy, but one thing that all can agree on is: worms are downright fascinating! There are more than 9,000 species of (segmented) worms in existence today.
Not to be confused with the leech, which is a carnivorous or bloodsucking worm, the bloodworm is the larvae of the midge and it feeds on algae and detritus. Blood worms are red because their blood plasma contains haemoglobin, like human blood. Also spelled “hemoglobin,” haemoglobin increases its ability to take up oxygen. The larvae [...]
The earthworm is by far the most vast and varied group of segmented worms on the planet. Just think, there are more than 2,700 different types or earthworm living in every corner of the earth today.
If you’re interested in worm pictures, you can always find them online, of course. However, some online resources for worm pictures are much better than others. Many online resources offer only a few worm pictures while others may offer hundreds. If you’re looking for a large number of worm pictures all in one place, there [...]
Worm bins are used for worm composting. Depending on the scale of your composting project, the size of the worm bin will vary. Some systems are “small scale” while others may be “large scale.” Small scale worm bins may be homemade or purchased from a retailer. Small scale worm bins are made of wood, plastic, [...]
Worm hole is defined as a hypothetical passage in space-time connecting widely separated parts of the universe. Worm hole has a second definition as well. It is also defined as a hole made by a burrowing worm. There are many different types of burrowing worms. Some are considered deep burrowing worms while others are considered [...]
They say flies are the filthiest insects on earth. Flies will feast on just about anything, including feces, dead animals, and even blood. They also eat nectar, plant sap, and other insects. At the opposite end of the spectrum are worms. Worms are among the “cleanest” insects on earth. They don’t dine on blood or [...]
The process for raising worms is much like the process for worm composting. The same materials used for composting worms are the same for raising worms. The reasons for using these materials are the same in both cases as well. The only difference between raising worms and composting worms using the same method is that [...]
Worms have the ability to coat themselves in mucus. Worms must coat themselves in mucus in order to absorb oxygen. By coating themselves in mucus, dissolved oxygen is free to pass into the worms bloodstream. About Worms There are more than 4,400 species of worms, with more than 2,700 species of earthworms alone. Earthworms can [...]
Red worms have so many different names and spellings, that it would be tough to list them all here, but just a few of the other names and spellings for red worms include: Red Wigglers, Red Wiggler, Brandlings, Earthworms, Earth Worms, Redworms, Manure Worms, Red Wiggler Worms, Trout Worms, Compost Worms, and Tiger Worms. Red [...]
Worm identification falls under the branch of zoology dealing with insects called, entomology. According to the MSN Encarta Encyclopedia: “Although insects were studied as early as the 4th century bc, particularly by Aristotle, the modern science did not begin to develop until the 17th century ad. The science of entomology received great impetus in the [...]
There are so many worms living inside the earth that it’s impossible to list them all here. That said, there are some worm groups that are larger than others such as the earthworm and the inch worm. While there are more than 4,400 different types of worms, there are 2,700 different types or earthworm alone [...]
There are several types of worms that can be used as bait for fish, reptiles, and birds. Two of the most popular types include the Bait Worm and the Meal Worm. Meal worms are the larva of the mealworm beetle, which is the species of darkling beetle. Because of their high protein content, meal worms [...]
Blackworms can be found in just about any city, town or rural area in the United States. They typically live in muddy areas, especially shallow water. Blackworms can be found in droves in ponds and marshes. It is not uncommon for blackworms to migrate to other warm, moist or humid areas. Blackworms belong to the [...]
While a lizard will lose its tail as a means of protection, if a worm loses either end (the anterior or the posterior) it’s usually at the hands of a predator, an unfortunate accident or a curious human that believes the worm will regenerate if they chop it in half. Unlike lizards, the worm protects [...]
There are literally hundreds of thousands of worm species in the world today and roughly 2,700 are earthworms. Although there are thousands of different species of worms around the world, worms share a number of common characteristics. Their physical characteristics are similar as well as their diet, reproduction, where they live, and defense mechanisms. Worm [...]
There are more than 2,700 species of earthworms in existence today and they can be found in just about every corner of the earth. They live in trees, in bark, and under rocks as well as along rivers and near springs, and ponds. Their favorite place to live, however, is in the earth’s rich soil. [...]
The woolly worm is actually a caterpillar or the larvae of the Isabella tiger moth. The tiger moth belongs to the arctiidae family, which has 11,000 species of moths around the world. The tiger moth is a beautiful creature with bright colors such as scarlet, yellow, orange, and white and rich hues ranging from black [...]
Did you know that worms are 1,000 times stronger than humans? Did you know that worms are hemaphrodites? This means they have both male and female sex organs! Worms are amazing creatures, so these are just a few interesting facts about our cold-blooded friends. Another interesting characteristic of the worm is its habitat. Worms live [...]
The hammerhead flatworm can reach up to 20 inches long and its body is very slimy, which allows it to move along the ground in a gliding motion. The body secretes mucus from glands on its belly or underside. The hammerhead is native to Indo-China, but it makes its way around the world by traveling in greenhouse plants.
While the banded woolly bear does not use its bristles for protection, it has another defense mechanism. If handled or threatened in any way, the banded woolly bear will simply play dead.
Whether you’re a farmer, a gardener or a novice, you may have experienced an inch worm infestation at one point or another. More than likely the inch worm infestation caused so much damage to your crops, plants or garden that you may have resorted to poisonous chemical remedies to treat the infestation. These remedies may have been effective, but you may have concerns about the toxic nature of these chemicals. Fortunately, there are several less toxic and non-toxic ways to control inch worm infestations.
The bristles or “setae” of the bristleworm are so tough that they can penetrate skin, causing a painful “sting.” Depending on the type of bristleworm, the sting can cause burning, inflammation, numbness, pain, redness, and swelling at the bite or sting site.
Believe it or not, the market for bait worms is huge in the U.S. and in most other parts of the world. It is estimated that in the state of Maine alone, more than 200 tons of bait worms are produced each year and in the UK, more than 700 tons are produced each year for both commercial and personal use.
Besides the Sahara Desert, it is unlikely that you will find large numbers of worms living in “sandy” areas, especially sandy beaches. You see, the vast majority of worms on our planet can only survive under certain conditions.
One of the most obvious differences between caterpillars and worms is caterpillars move around on three pairs of legs, while worms have no limbs at all. Worms move around by contracting their segments.
Worms prefer complete darkness because the light affects them in the worst way. Light does not kill worms, but if worms spend too much time in the light (typically one hour), they become paralyzed.
If you think you can make an average, everyday worm glow in the dark by feeding it certain foods or poking it with a stick, think again! Not to be confused with glow worm beetles, glow worms have the amazing ability to produce light naturally and they can only be found in Australia and New Zealand.
In worm anatomy, the tube-within-a tube digestive system is efficient and sometimes complex. The term is a reference to the one-way food consumption process that’s common in all annelids.
Worms, grubs, and insect larvae are tasty treats for many individuals around the world. They’re also gaining popularity in the U.S., for their protein and low-fat value.
The massive amount of living creatures in a worm bin or farm is mainly beneficial. However, predators and other creatures find the composting process attractive, to the detriment of worm health.
Earthworm bins are alive with activity. Many beneficial creatures, along with bacteria, molds, and fungi make it a comfortable and healthy environment.
Pot worms commonly share space in earthworm farms and compost piles. They can greatly outnumber their segmented relatives without causing any harm.
Sometimes called the “worms that suck blood, medicinal leeches are performing valuable services. They produce anticoagulants in their saliva that reduce or eliminate the dangers of clots in some individuals.
Millipedes are often identified as crusty, crunchy “worms.” Generally harmless, even in large numbers, millipedes often invade homes, particularly basements and crawl spaces.
Segmented worms are placed in the phylum Annelida, which consists of over 12,000 species of segmented worms grouped into three classes comprising freshwater worms and earthworms, marine worms, and leeches.
There are nearly 10,000 species of bristle worm. Bristle worms can be tiny or large. Bristle worms can be benign or predatory. In fact, the bristle worm family is as diverse a worm family as one could hope to find.
What do you know about leeches? Once valued, then reviled, the leech has never been completely understood. To some, it is a lifesaving tool of medicine; to others, leeches are deadly predators. Who’s right?
So you think all earthworms are the same? Think again! There are 2700 known species of earthworms on our planet!
Do you know how many species of segmented worms there are? Did you know that segmented worms are highly evolved, with a circulatory system and complex nervous system? There are over 12,000 species of segmented worm – how many segmented worms can you name?
