Gilfach (west), Top Llangynwyd

 A bout of fine weather at 1500 hrs had me travelling up to Top Llan to see what hoverflies were out after the rain. I wasn't disappointed with 37 species recorded. New species for  the year are coming hard to get but Epistrophe grossulariae (1) was my 102nd for 2021. Most numerous species were Platycheirus albimanus (50) and Eristalis pertinax (50). A lot of the more local/scarcer species were seen and included Didea fasciata (1), Eriozona syrphoides (1 - my 7th of the year), Eupeodes lapponicus (1), Scaeva selenitica (2) and Helophilus hybridus (1).

Eriozona syrphoides - my 7th of the year of this scarce hoverfly species.
Didea fasciata
Helophilus trivittatus
Scaeva selenitica
Scaeva pyrastri
Sericomyia silentis
Eupeodes male - can't be done through photos but this one keys out at "bucculatus" under a hand lens. Kept the specimen for Roger Morris to go over at the end of the year.

Here's a selection of other insect species out today.

Ichneumon sarcitorius
