Gilfach (west), Maesteg [Top Llan]

It's not since 2nd June (35) have I had 30+ species of hoverfly (31) in a day. So today's numbers around the lanes next to the forestry was indeed welcome. New for the year or not seen for a while were Didea fasciata, Dasysyrphus albostriatus, Epistrophe grossulariae, Leucozona glaucia and Lejogaster metallina.

Ten species of butterfly were headed by Comma, Small Copper and ever increasing numbers of Ringlet (60). The Longhorn beetle Leptura maculata was recorded, and a Sulphur Beetle was on Hogweed. I've checked my records and I think it is new for the valley, I've only ever seen them down at the coast at Kenfig NR, inland records are very few and far between. Silver Y and Pammene aurana moths were feeding on Hogweed as were large numbers of Orange-legged Furrow Bee, Tree Bumblebee and a few Field Cuckoobee. New blooms for the year were Upright Hedge Parsley and Lesser Burdock.


 Epistrophe grossulariae
 Dasysyrphus albostriatus
 Leucozona glaucia
 Chrysogaster - I've taken this fly as a specimen and it keys out to Chrysogaster cremiteriorum which would be new for the valley. So will have to wait for the answer at the end of the year when I send the specimens to the Hoverfly Recording Scheme for identification. Although from the picture you can see the wings are clear and have yellow base to them and the sides of the thorax are dusted grey, this separates them from the other two Chrysogaster.
 Sulphur Beetle - new for the valley and usually coastal in Glamorgan
