Not even suggesting a family on this one - not solely because it would only be wrong, but also becuase I've tried and failed to find one that looks likely.

So I'm leaving it at Nematoceran, and hoping someone else can tell me more.

(If it's not a nematoceran, I will cry).

Bosham, West Sussex

3 March 2012.

Amongst the floating irises on an ornamental pond.

Tiny - not more than 5mm, probably a fair bit less (not including legs)

Looks like Ceratopogonidae.

Et tu, Brute :o

I could hardly resist on the ides of march, now, could I?

Updating title and (with a quick check), confirming no need to cry. Excellent.

Thanks,

Will.

I think Chironomidae more likely for this female

---

It is a huge relief when other people can be uncertain at family level - even if it is just because of a bad photo.

Thanks, and changing title.

Will.

Glad to be of service :D. Of course Tony is right.

Odd one. It appears to have too many antenna segments. Female Chironomidae with more than 6 segments in the flagellum have M-Cu crossvein present or (rarely) M and Cu close together without an obvious crossvein. Males normally have more hairs on the antenna, and the blunt-tipped abdomen suggests female. If the antenna has only six segments with sculpturing creating the illusion of more, it's a very hairy female Orthocladiinae.
