Hi, Today I saw several Rhamphomyia species, one of them with peculiar fore feet ("swollen basal tarsomere" I would call it). I suppose ID will be easy! Many thanks, Sundew Sundew attached the following image:  [159.61Kb] Edited by Sundew on 09-05-2010 20:30 |

I see... A short proboscis alone does not make a Rhamphomyia  . And Hilara is difficult to ID. So we might come to a dead end with Hilara spec. One more question: are only the males' feet thickened? I saw rather similar animals with "normal" feet; I shall post them later.Thanks again, Sundew |

Generally it is only the males that have these modified tarsi - they are supposedly used for wrapping nuptial gifts of prey in silk, which occupies the females whilst they mate (although some have skipped the tiring part of capturing prey, and just offer an empty silk packet): lecture over. |

Phil: many thanks for the very interesting lecture! I enjoyed it a lot. What a funny behaviour... Paul: thanks for supplying a group name. Now my next question: do the new pics show the female of that silk-producing male (it was sitting nearby), or is it something else? (In my opinion, they would make a very nice couple!)

Indeed, the female.
