Expert confirmation is needed but this looks like Tipula paludosa to me : eye separation is quite broad, several times the width of the basal antennal segment. In the very similar Tipula oleracea the area between the eyes is very narrow, only as wide as the width of the basal antennal segment. Wings of female T. paludosa are shorter than the abdomen (can't be assessed here.Wings of female T. oleracea are clearly longer than the abdomen. Phallic (genitalia) characters are different between the two confirming that there are two (sister) species.. Tipula paludosa and T. oleraceaare extremely similar biologically. Tipula paludosa completes a single generation annually, with adult emergence beginning in late August, and their numbers peaking in September and continuing into October. Tipula oleracea, on the other hand, completes two generations annually, with adult emergence in the spring (late May to July) and again in the Autumn (mid August to late September or October) Both species are turf and pasture pests. Tipula paludosa is probably the most injurious and widespread crane fly in northern Europe. Slainte Robert Edited by Robert Nash on 23-10-2006 14:37 |
