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 Iain Iain MacGowan |

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. Nikita Vikhrev - Zool Museum of Moscow University |
