Description:

On one of our nature rambles we caught a photo of this beautiful bumble bee on a Marsh Thistle. Are we correct in our id of Bombus pascuorum?
Thanks.

Carder Bee

Thanks Syrphus, but what do you mean by 'black hairs'? (I'm new to bumble bees!)

The two brown carders we have

The two brown carders we have in Scotland (pascuorum and muscorum) are very similar. The first is very common almost everywhere except the W Isles and Shetland. The other is much scarcer.

Both can be devoid of black hairs on the abdomen, when ID becomes very tricky. If you have one with a lot of black hair on the abdomen, it will be pascuorum. With experience you can do them in the field, but the only certain way for a beginner is a bit of dissection.
