A colleague on another forum took some photos of Villa species bee-flies which appeared to be ovipositing just in damp mud with no obvious bee nests around. Are all Bee-flies parasitoids of bees ?

Actually, it is a female filling up her "sand chamber", a hollow space in the abdomen where she stores fine sand particles. Then, when she is laying her eggs in the host's nest, each egg is covered and camouflaged using this sand.

As far as i know most Bombyliidae are ectoparasitoides of the pupae or prepupae of the host invertebrate with a few attacking egg pods so strictly speaking are predators. None are "cuckoos" ie brood parasites or cleptoparasitoides, they attack the insect itself rather than usurp its food store as cleptoparasitoides do.

The first part of viktors answer is correct but Villa do not direct their eggs at host nests but broadcast their eggs in any likely habitat. Villa most frequently attack Lepidoptera pupae. Even those species of beeflies which parasitise solitary bees are still prone to scatter their eggs at anything looking vaguely like a hole in the ground.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
