Hello, are the darker flies males? Because Lonchoptera bifurcata does not produce males in our region (northwest Germany), these are likely to be L. lutea, right? (I don't know anything about the 7 rarer Lonchoptera species listed for Germany.) Ca. 2,5-3 mm, at night in garden.

Lonchoptera can be sexed by the last wing veins. Females have A1+CuA2 curved forward to end in CuA1. Males have the vein ending in wing margin. http://www.drawwi...hopteridae |

I had read about sexual dimorphism in wing venation of Lonchoptera, but with no given details. And I don't know if I make out the difference correctly on these photos with overlapping wings.

Some of the keys are valid for Europe, or at least useful in Europe, and the key to families should work for all common species. |
