Wildlife Spotting

I agree with Martini.it is a great click indeed.

Probably belonging to the psychodid tribe Paramormiini

http://www.projectnoah.org/spottings/30049039 not the best pi though.

It looks quite stunning. I know many of these are quite dull. Flies (Di=two and pteros=wing) have only two wings like yours does and it is a true fly. Moths have four wings and tapered or feathered antennae but these wings and antennae are very typical of moth flies. You will read that several subfamilies exist with habitats more diverse than drains. I believe you have found one of the more spectacular ones.

This is a great click of a moth fly found in drainpipes. http://en.wikipedia.org/wiki/Psychodidae
