Michelle writes to us her daughter found a caterpillar-like creature (pictured below) on her leg when walking home from the library. “She did go into one of her friend’s yards and knocked on their door: they weren’t home so she continued to walk home via the road. She didn’t go into any bushy or forested areas on the way home but found this little caterpillar thing crawling on her leg. So, we wanted to identify it and find out what kind of caterpillar or larvae it is. We did notice that it created a silk or web-like substance.” Based on the photo, we agree that this looks like a caterpillar. Unfortunately, the lighting in the photo makes it hard to see what color the caterpillar really is: we think it looks yellow, but that could also be the lighting. It could very well be a light green or gray color.

“I found this little guy in my front yard and can not find out what he is”, states this reader in Anza, California. “I have a big beautiful Catalpa tree that I think he may have fell out of”, she says of the pale yellow caterpillar-like organism pictured below.

“I was cleaning my room and found this particular caterpillar (I think) on my cat’s food bowl”, writes this reader about the yellow creature below. Our reader asks that we tell him if his cat has worms or if it is possible that the organism came in from the outdoors.

A bright, yellow caterpillar with gray spots and big black eyes was found by one of our readers. She did not pose any question, but simply wanted to share these excellent photos with us. This article will address what this caterpillar is in case any of our other readers happens upon one.

A couple of days ago a reader sent us an amazing picture of a yellow caterpillar with black eyes. (These “eyes” are in fact eyespots, which serve no optical function, but more on this in a moment.) She had found a couple of the yellow caterpillars on her back porch and was wondering if we might be able to help with the task of identification. Although caterpillars can be extremely difficult to identify because of the sheer number of different species, we are reasonably confident our reader found a Spicebush Swallowtail caterpillar, one of the hundreds of species of Swallowtail caterpillars.

Via the All About Worms Facebook page, we recently received a question about a “kind of worm” that appears to have two eyes. Overall, the worm is yellow, but on one end of its body it has black spots that look exactly like eyes. The eyes on the yellow worm are quite large, to the point that they look somewhat cartoonish. The reader sent a superb picture of the creature and only asked what kind of worm it is. So, we are tasked with a question of identification: what kind of worms are yellow and have large eyes?

We recently received a question through the All About Worms Facebook page about what we suspect to be some sort of caterpillar turning into a butterfly. The caterpillar, if it is a caterpillar, was evidently found in a dead tree stump, although the pictures our reader sent (included below) don’t appear to depict a dead tree stump. The creature is yellow – or rather it is a yellowish, off-white color – and has a plump, segmented body (a body that might be protecting the caterpillar as it turns into a butterfly, if this indeed what is happening). What is the yellow caterpillar on the dead tree stump, and could it be turning into a butterfly (or moth)?

A reader recently sent us a very direct and simple question. The reader merely sent a picture of what appears to be a caterpillar – it was referred to as a worm, though – and asked what the “worm” was and what it ate. The caterpillar (or what we believe to be a caterpillar) is almost entirely yellow, although it has some gray stripes on it. They aren’t perfectly horizontal stripes, however, as they make more a “v” shape. There are also dozens (if not hundreds) of small black dots on the creature’s back. What is this yellow caterpillar with gray stripes and black dots on its back, if indeed it is a caterpillar at all?

A little while ago, we received a question from a reader asking about a worm he found near his garden. It is primarily yellow, but it has small black stripes on it too. The reader found this yellow creature with black stripes, which is shaped like small tube, on a tree. He sent a nice picture of the worm (which is in fact probably a caterpillar), which is below. He was wondering what kind of worm he found, and also if it was “aregetic” to humans. “Aregetic” is not a word, as far as we and Google can tell, so we suspect the reader might have meant something like “harmful” or “dangerous,” as this is the most common concern that readers have with worms (or caterpillars) they find. What is this worm or caterpillar, and is it dangerous?
