Bee Diptych Panel

Bee Diptych Panel
Had another opportunity to photograph 'Bees in Flight' Today. I am getting a bit better. This time I shot a whopping 591 shots over a 30 minute period. 
I got quite a few (6) I was happy with. These shots prove the old saying 'You wait forever for a bus to come along and then two turn up at once'
I did think of calling this one 'In and Out'  
I think this is a White-tailed bumblebee (Bombus lucorum), perhaps someone can help me there. We also have in our garden one type with a brown bottom that may be an 'Early Bumblebee'.
