Hi, still in Comana Natural Park. in the morning a trip on the water to photo birds (not very successfully) and late afternoon a trip in the forest with several flies photographed/collected (much more collected). this small flies (~3mm) are killing me here in he forest, everywhere are with hundred, trying to get in the eye/nose/ears... collected a lot of them. now reading thru the forum, comments on image and so on i think this is from Phortica semivirgo (from what i see: partly darkened fourth tarsal segments and wholely pale posterior margin of the eye), wrong or not. thanks in advance for the help, cosmln cosmln attached the following image:  [76.39Kb] |

these Portica flies are so annoying!  They constantly attack our face.  |

Hi Cosmln, It certainly looks like Phortica semivirgo, but I have thought that of other specimens before and have been proved wrong . But still ......

Hi Cosmln, Jan Maca wrote the following:
Yes, it is almost certainly P. semivirgo, but it is always worth to prove determination by the study of terminalia. It is easy in males. Sometimes the aedeagus is visible; if not, it is usually possible to make tip of aedeagus free by a needle (in alcohol specimens). By the way, only two localities of P. semivirgo from Romania have been published (Turda and Mehadia) despite this species must be common in the country. What concerns the annoying behavior of Phortica flies, some information may be found in the article http://www3.inter...0/abstract as well as in the papers quoted there.

Hi to both of Jan  thanks for your interests. i have collected several tens of specimens collected from several spots from a 25000 Ha area. i will keep some specimens for Jan Maca (i already keep drosophilids for him). i think Paul will wish some specimens, any other? i will keep for me just 4 or something like that. cosmln |
