Chironomid
Rye Harbour NR 18th August this year. I'm thinking Orthocladiinae but can anybody go any further? Thanks

Re: Chironomid
Most Orthocladiinae with black and yellow legs turn out to be Cricotopus. Can't see any reason why this shouldn't be one.

Re: Chironomid
Thanks Tony. I'll slide mount the abdomen and see if I can get to species

Re: Chironomid
Managed to slide mount the hypopygium (not hugely successfully) and run it through the key. I think I have C. sylvestris. Anyone have any experience of this species

Re: Chironomid
Well, there are some very similar species, so I'm not 100%sure, but the genitalia look OK for sylvestris, and the colour pattern is right for sylvestris too.

Re: Chironomid
Thanks Tony. My first attempt at orthoclads so good to know I'm close.
