Observed last month near a stream in east China (Zhejiang province), body length approx. 5mm. Judging from the general appearance and wing venation, is Gymnopternus sp. a good candidate? Thanks in advance!

Unfortunately, it is impossible to separate Chinese Gymnopternus from Hercostomus without microscope.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
