Ken nailed it
The genus Microdon (member of the Syrphidae, the flower flies) has these weird larvae that live in ant nests. Evidently they can chemically mimic the smells of ants, and so are protected by them. When the larvae were first discovered, at least one researcher thought they were not insects but crustaceans or something similar.
