Butterfly, Bee and Hoverfly, all at Montreathmont Forest

Butterfly, Bee and Hoverfly, all at Montreathmont Forest and the second species seen in my new pond, Midge larva. I liked the first species better and hope they may return as they might predate the midgies.

Reasonably confident this is a Bog Hoverfly, haven't tried to ID the flies

Common Blue Butterfly female

Looks like a Cuckoo Bee, perhaps a Gipsy Cuckoo?

Maybe as many as 500 of these midge larva in my newly dug pond, joy!
