hi flyforum, I thought this little fly (4-5mm) belongs to Phoridae and is perhabs a diplonevra sp.? This fly seems to have some white tip on the end of the wing, or was it lightreflection? place: Amsterdam forest, bridge near water Robert Heemskerk attached the following image:  [96.22Kb] |

I'd say Megaselia. But 4-5 mm would be huge for this genus...

Thanks Kahis, I think I am not so strong in calculating these small fly-measurements But 3mm is more likely I think.. Lot's of Megaselia sp.!  , this morning I didn't know about their existence at all! |

In http://www.phorid...ridfaq.htm There are about 3,000 described species of phorids, but the actual number is much higher. Published estimates by Disney range from 20,000-50,000; my own work on New World phorids has shown that there is at least 10 times the described diversity out there (thus at least 30,000 species). Phorids are small (1-7mm) and poorly known. Most of the keys don't work because there are so many undescribed species, and the frustration factor is large. Additionally, one genus, Megaselia, accounts for nearly half the family, and its taxonomy is a mess. Only the fauna of England can be approached with any degree of confidence, thanks to Disney's Handbook on the British Megaselia. Specimens of some genera, such as many Megaselia, are impossible to identify at this time. |
