Looking through my photos I found this curiosity from a couple of years ago:

Looks like a large bumble bee with proboscis extended, but the wings are held out from the body when resting and there is only one pair, i.e. diptera, so a fly, not a bee. These things come out in March. Apparently they are cuckoo-like parasites of bumble bee nests, in which they lay their eggs. These hatch into larvae that eat the bee larvae, then pupate and emerge as weirdo fake bees.
