Distribution

This species is present in most of Europe, in East Palearctic ecozone, in the Near East and in North Africa.[1]

Description
Volucella inanis on Succisa pratensis

The adults reach 15–17 mm (0.59–0.67 in) long. They have three yellow bands on an otherwise black abdomen and thus closely resemble wasps in a form of mimicry. The first two bands are completely or partially interrupted by a black wedge. The head has feather-like antennae and the wings have darkened patches in the middle and on the tip.

Biology

Volucella inanis can be encountered from early July to early September, feeding on flowers of various species such as yarrow (Achillea millefolium), dill (Anethum graveolens), heather (Erica species), thistles (genera Carduus, Cirsium, and Onopordum) and Buddleja davidii.

The female lays eggs in the nests of social wasps and hornets (Vespa crabro, Vespula germanica, etc.). The larvae of this hoverfly are ectoparasites of larvae of the wasps.[2]

gollark: No, I mean a stack in the sense of a stack machine instead of a register machine.
gollark: Maybe I should just do stacks, those are fun.
gollark: Yaaay!
gollark: I've just realized that if I have a register which always contains 0, some of my instructions just become special cases of other instructions, which is quite neat.
gollark: SPARC sounds very strange.
