Also seen were Bryotropha terrella and Cydia ulicetana. The Longhorn Beetle Stictoleptura rubra (male) and Larch Ladybird. As well as 16 species of previously recorded hoverflies.
The family "Bibionidae" or St Mark's Flies as they are commonly known contains 18 species - Bibio (14) and Dilophus (4). 14 species have been recorded in Wales of which 8 are in Glamorgan according to the NBN Gateway. The species below is Bibio pomonae who's English name is - The Heather Fly and seems to be quite common in the upper valley, where Heather grows although this one was feeding on Hogweed. I also recorded them feeding on Ragwort and the Butterfly Bush. The males have large eyes like this one, while the females eyes are very small, making them look like a different species. Bibio have spurs on the tibia where it joins the tarsi, while Dilophus does not. The leg pattern on this species is diagnostic for the males.

Not a rare fly by any means. But it has not been recorded with regularity in Glamorgan - so worth a post, it is a member of the Tachinid family. Interesting fact about this species is that the adult female lays its eggs on the beetle Common Cockchafer or Maybug as it is better known.

Photographed this rare hoverfly at Cwm Drysiog, Maesteg on 7th August 2015 - "Eupeodes lapponicus". It took a while for experts to get back to me with confirmation. From the NBN Gateway map you can see that there has been only a few records in Britain. Although not fully up to date, it does show how rare this species is in Britain. There is a good chance that it is a Glamorgan first. The diagnostic feature is the strong dip in the R4+5 vein on the wing
