Hello Jamie

I attach the file with the August records added. This has increased the number of species I've identified from this year to 170, of which surprisingly only 24 are in common with the 87 species recorded last year.

I have indicated where there is conservation status for some of the craneflies and fungus gnats. The craneflies haven't been reviewed since 1991 and the Notable species are now known to be more widespread. Tasiocera jenkinsoni is a significant find with only 3 previous British records, two of them from Sussex, but Tasiocera are very tiny, smaller than most fungus gnats, and dark coloured. The five British species all look alike and are only distinguished on male genitalia, but there are two common spring flying species and any found as late as August are likely to be one of the three rarer species.

The two Mycetophila species mentioned as first recorded in Britain in recent years are possibly new arrivals in this country, which have now spread widely in the south, but useful to have these additional records. With last year's records there are now 83 species of fungus gnats recorded, which should rise with an autumn visit.

Best wishes
Peter
