Re: Cranefly

A rather tricky one, Darwyn. My guess would be Tipula (Yamatotipula) lateralis but there are several rather similar alternatives so you probably need some other angles to be absolutely certain.

Perhaps one of the cranefly experts will appear and shed more light on this subject.

Re: Cranefly

Hi Darwyn. I agree with Geoff.  Most of this subgenus look similar and extra clues are provided by habitat details.  The common one in habitats usually near moving water is T. lateralis, with a black line down each side of the abdomen.  Confirmatory ID is usually by the shape of the outer claspers of the males.

Re: Cranefly

Thanks both. It's the only cranefly I shot on our Stoke field week. Under those big leaves by the side of Folly Pond at Cholmondeley, Cheshire. I'll take a look at the other records from there (which I'm now in the process of compiling), if someone else got that species there (or near) then I'll do no harm if I record it as such.

Re: Cranefly

Oh well, that didn't work. The only Tipula from there was Martin Drake's Tipula fascipennis. Is that likely?
