Hi, On 17 September I came across a small fly (about 5 mm) that moved slowly over a stinging nettle leaf, licking honey dew from willow bark aphids. A small stream was nearby. My first thought was Hymenoptera because of the long antennae, but then I saw the pink haltere knobs... I have no idea where to put this animal. Though I tried very hard to get a clear view of the wing venation, it was impossible (late in the evening, strong reflections by the flash). But if it was a sciarid, the typical fork of wing vein M should be a bit visible, and the fly would be very colourful for a sciarid. What looked strange to me was the combination of characters - long, bristly antennae with swollen pedicel, - some short spines on the lower side of femur 1, - dark, thickened tibia tips (rather tufts of hair than spurs), - long curved claws, - legs without long spines (so no fungus gnats). Who knows such a fly? Help is urgently needed. The location is southwestern Germany west of Stuttgart. Looking forward to replies, thanks in advance, Sundew Sundew attached the following image:  [293.51Kb] |

Some details. Upper right: spines on femur 1. Middle: antenna base with swollen pedicel. Lower right: hind leg with peculiar tip of tibia. No better pics, sorry. Sundew attached the following image:  [252.75Kb] |
