Pink fly

Is this some sort of dagger-fly? It is thoroughly pale pink.
Seen on my tripod on the sea-wall in Essex.

Re: Pink fly

Freshly emerged female Chironomini (Chironomidae) - in several species, the haemoglobin that gives the larvae (bloodworms) their colour, is retained by the pupa and is passed on to the adult. It's not clear what advantage the air-breathing adult derives from so much haemoglobin - it may just be a case of being easiest to deal with it over a longer period, than trying to dump it all before eclosion. The red colour will fade, and the green, brown or black colour of the mature adult will soon develop.
