Hi, two for you here. The first is definitely a bee, but is it B. hypnorum? 
The second, I have no idea about! Is it a bee or is it a fly? 
thanks, Jo

2 is a leaf-cutter bee, Megachile sp.
Would like to see the rear abdomen of 1 to be sure about this. B. hypnorum has a white rear end. |

Evening Jo,
We really need to see the back-end of Tree Bumblebee Bombus hypnorum suspects, but they shouldn't have white hairs at the bottom of the thorax's side ( I think they're black). This makes me suspect it's the Common Carder-bee, Bombus pascuorum.
The second may be Megachile dorsalis or similar, it's quite greyish to me ( or a faded Megachile sp. along the lines of M. willughbiella).
Take care, Jason  |

Thanks for the id on the first one! As I was posting I realised I hadn't uploaded the pic showing the abdomen so here it is: 
As you can see they have built their nest in this hole in the ground. thanks for the speedy reply Aeshna.
Jo

Yes, looks like B. pascuorum. |

Ah, showing it perfectly - he must have known! Yes, Bombus pascuorum. |

Thanks, I can never tell those apart! I have had a confirmed B. hypnorum or two in the same area so wanted to be sure. thanks again, Jo

Well...
- Common Carder-bee Bombus pascuorum and Tree Bumblebee B. hypnorum both have gingery hairs on top of the thorax, but in the case of hypnorum it tends to be brighter.
- The hairs below this on hypnorum's side are black, but can appear whitish grey with pascuorum.
- In pascuorum the abdomen is often blackish with some grey and white barring, but with hypnorum it's pure black with an obvious white tip.
In general, if you need to question it it is usually Bombus pascuorum. With Bombus hypnorum, the colours are sharper and better defined and as a result you just know.
Still, wear/fade can kick-in later in the season and make determination harder, so feel free to post here to check specimens!  |

Thanks for that, it'd be so much easier if they all came ready-labelled!

Yes, pascuorum. Also, hypnorum nests high (there the name tree bumblebee), including under roof tiles and eaves and in bird boxes.
The Megachile looks like a male, but no boxing gloves on the front legs so you can exclude the common M. willughbiella.
