I always have a good look at the beetles and flies that are attracted to my moth trap, as some of them are very distinctive. I was amazed by a fly that Keith Tailby found while we were out mothing in the New Forest so took its photograph for later identification.

Rhamphomyia marginata

I was pleased to discover that it was a rather uncommon Empid fly, Rhamphomyia marginata. The NBN Gateway site shows it in only a few 10K squares in south east England so I am attempting to find out a more accurate picture of its distribution at present. It goes to show that moth trapping can turn up some interesting species in the "by-catch" category.
