Any help would be appreciated, although I understand if it's not possible to ID some of them based on just a photo.

Possible Eristalis species?

Possible Eupeodes luniger?

Last one! Could this be Cheilosia vernalis, or am I being a bit optimistic hoping for an ID to species level.

Welcome to the forum Bill ... just a small tip though - it helps if you post each species in a different thread. Mixed threads can be confusing to follow and difficult to search for :)

Apologies, Chris. I guess I'm just used to uploading photos in bulk to one post; thought it would be silly to clog up the forum with four different threads, but I'll take note for next time :)

Hi Bill,

the first two flies are definitely Eristalis as you can see the dipped vein. Pale front tarsi mark both out as E. pertinax, the second fly looks like a hairy spring-brood specimen.

E. luniger looks probable but from this picture it's difficult to be certain, and I don't think there are that many Cheilosia that can be readily identified from a picture
