Bright Yellow-Green Caterpillar on Driveway is a Polyphemus Moth Caterpillar

A “little critter” was found on this reader’s driveway last summer in her small North Texas town. The critter appears to be a bright green color and has a brown face, split down the middle by what we assume to be access to its mouth.

Black and Yellow Worm is an Orange-tipped Oakworm

A rather large, creature was found in the suburbs of Philadelphia, PA by a woman who wonders if we can identify it for her. From the excellent photograph provided by our reader, one can see that the creature in question is black with yellow stripes, and is about 2.5-inches in length, according to our reader.

Yellow Caterpillar with Black Eyes (or Eyespots)

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.

Yellow Worm with Eyes

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?

A Caterpillar Turning Into a Butterfly (with Pictures)

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 Yellow and Gray Caterpillar

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?

Yellow Caterpillars with Black Stripes

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?
