Anyone good with identifying bees?

[flindorama]

We have some bees nesting in our roof. I'm 100% sure they aren't honeybees or wasps but I can't figure out what they are. I think but I'm not 100% sure this might be one that flew into our sunroom and promptly disappeared and turned up dead before I could let it out!! Poor thing must have battered itself off the window. It's looking a bit rough! I thought the ones flying into the best had a slightly lighter bum but this one isn't very clear. Anyone know of bees that nest in roofs??

Another one just flew in. This is definitely a better pic and definitely one from.the nest

They could be Tree Bumblebees. We had a nestbox that wrens attempted to nest in but they gave up as it was taken over by these bees. They are a nuisance tbh!

A friend posted this the other day, may help. I’m gobsmacked there are so many varieties!

The first pic is a different species from the second. The second has the rusty furry shoulders of the tree bumblebee but I'm not convinced it has the white tail.

HerRoyalNotness's poster I don't think has all the bee species, and it certainly doesn't have all the hoverflies that mimic bees.

It looks like a mining bee.

Hmmm ... Now I'm not sure. There are lots of bee mimics out there and those legs look too "leggy" for a bee ...

I think the second picture is a hoverfly but a bee-mimic type. They often nest in old wasps nests so that's what you might have had in your roofspace. They don't sting and will likely move on for next year. The first picture is tricky to see and the second is more bee-like and might be a mining bee.
