Larvae in Laundry Room Remain Unidentified

Recently, we received several amazing photographs of a couple of creatures. Our reader, who submitted them, says that he found them in his laundry room. He describes them as caterpillars or larvae that are about 1/2” (~1.25cm) long. He would like us to help him identify their species.Identifying larvae and caterpillars is notoriously difficult. This is because all larvae change appearance as they move from one instar to another. Also, many species’ larvae look alike. So, two larvae of different species may look more alike than two larvae of the same species in different instars.Many larvae are fussy eaters, so it is often easiest to identify a caterpillar or larva by its eating habits. However, we do not know of any larvae that eat laundry, so that method will not help Continue reading [...]

Today, we are going to discuss instars in depth, so that we all know exactly what we are talking about.According to the Amateur Entomologists’ Society, an instar is “the name given to the developmental stage of an arthropod between moults.” So, to understand instars, we must first know what “moult” (spelled “molt” in the US) means.Arthropods (animals such as butterflies, insects, spiders, and centipedes) go through several life stages as they grow from infants to adults, much like humans. However, humans and arthropods have different skeletal systems. Our bones are a living part of our bodies. They grow along with our muscles and skin.Butterflies and other arthropods have exoskeletons. They Continue reading [...]

Dead Black Creature is Probably a Slug

We received some very interesting pictures from a man who found a creature in his living room. The critter appeared to be dried out and dead. It was about 1.25” (~3.2cm) long. Its body was black in color, though its underside was brown. The interesting thing is that it has two or three hook-like appendages around its mouth. He has scoured the internet, but has not been able to identify it. Continue reading [...]

To Get Rid of Centipedes, Take Away Their Food!
