A reader recently sent us a photo of some sort of white and yellow larva, or perhaps a whitish, yellowish larva is the better way to put it because the colors basically blend together. The reader said the larvae “moves like a caterpillar,” and she said it doesn’t look like a worm or slug, and all of this contributes to our belief that our reader found a type of larva. (Caterpillars are larvae, for the record.) The reader found the creature on her leg when she was out walking and she can’t seem to find out any information about it. Technically, the reader didn’t ask any question, but we presume she wants to know what the white and yellow larva she found is, so this is what we have directed our attention toward.
