Gilfach (west) [SS8487]

 Very hot today [30c] so wasn't expecting much hoverfly activity, but some of the shaded areas containing Hogweed and Bramble were quite busy with feeding insects. So surprisingly I recorded 34 species. New for the year were Platycheirus angustatus, Scaeva pyrastri and Eupeodes lapponicus, taking me to 90 species for the year. Other highlights included Dasysyrphus albostriatus (5), Cheilosia vernalis (2) and Eupeodes corollae (8) which I believe were possibly migrants as this area rarely sees them recorded. Most numerous species was again Meliscaeva cinctella (45) and Cheilosia impressa (40).

Other insects included two Red Admiral butterflies, an emergence of Harlequin ladybirds, Violet Ground Beetle and an Angle Shades caterpillar.

Dasysyrphus albostriatus
Eupeodes corollae
Scaeva pyrastri
Xylota segnis - unusual to see this pollen syphoning species feeding on any flower species let alone Hogweed.
