Hi,

this pupa was found in decaying wood of alnus, May 2011, Northern Germany. Is it a Tipulidae and is it possible to identify it?

Thanks
Thomas

It is definitely a Tipulidae, but I'm not certain about the identity. It may be Dictenidia, Ctenophora or perhaps even Tipula flavolineata, but I don't thinks so.

Although not all characters are visible, the key in Theowald 1957 runs to Dictenidia bimaculata, one of the most common xylophagous species.

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
