Yellow Worm Dangling from Silk Line is a Clothes Moth Caterpillar

“Any idea what this worm is?” asks Luke in his submission regarding the tiny, yellow, worm-like creature pictured below. “It looks very similar to a meal moth larva but more yellow, with a larger spot on its back, and a light colored head. I found it dangling from a really thin silk line off a tree.” Now, if it were not for that last piece of context, we would have identified this as a mealworm (which is not to be confused with the Indianmeal moth larva that Luke mentions). Mealworms are larvae of darkling beetles, but as such, they cannot produce silk/web like many species of caterpillars can. This is why context is so important. Without that piece of information, we would have provided a false identification (which is not to say that we have not provided incorrect identifications in the past, even with ample context: we’re only human after all!).

Half White, Half Black Worms By Rabbit Cage Could be Casemaking Clothes Moth Caterpillars

“I’ve seen these worms the last two mornings on my kitchen floor next to my rabbit cage”, writes Matthew about the curious creature pictured below. “Can you identify them? They’re TINY, with a half white, half black body.” First of all, thank you for the excellent photograph Matthew: we see exactly what you mean by the worm’s half white, half black body, and this is something we haven’t quite seen before. The thinner, white part resembles that of a generic insect larva (many of them being a similar, translucent white color), while the thicker, black part looks almost like a shell encasing the lower half of the worm.
