Hi Nikita
In Lonchaeidae hairy eyes are most commonly found in species which fly early in the spring or are montane or boreal so I guess the advantage is in providing some thermal protection

In Chironomidae, Drosophilidae, and Tachinidae I have not noticed a correlation between temperature and eye hair.

Iain and John, thank you for your reactions.
1. I delaied with reply reading pdf: "Insects have hairy eyes that reduce particle deposition, Amador_et_al, 2015" Alas, not very informative paper.
2. Looking at Muscidae family, thermal protection may has sense: hairy eyes are typical for such a cold-resistan genera as Thricops, Drymea, Phaonia. But there are contrexamples as well^ in Hydrotaea irritans group eyes are hairy only in southern H. penicillata.

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
