Hello, here I am rather sure with family Trichoceridae. But is the genus Trichcera correct, and can perhaps something be said about the species? (My guess is not.) The mite had about 1cm wing lenght. I found it in my garden near Cologne last weekend. Thanks, Michael Michael Becker attached the following image:  [69.57Kb] Edited by Michael Becker on 12-03-2009 17:54 |

Hello, Michael, this is indeed a Trichocera and one of the most usual species this time of year is T. hiemalis. Some of the features of this species are visible on the photo too, but of course I would't place a sure name.  Andrius |

Hello, indeed I photographed a mite, that is everywhere around here in masses. But was not sure, T. hiemalis is really the most frequent species in the moment. What features are visible here? Or what features at all has T. hiemalis distinguishing it from the other Trichocera species? Thanks, Michael |

Hi, the best way is of course seeing the genitalia. But other features suggesting hiemalis are slightly enlarged first antennal flagellomere, shape of D cell and diverging M1 and M2 veins (that is going not parallel towards the wing edge). As I said these wouldn't be enough for a sure identification, but may help when nothing else is visible  Andrius |
