There is no doubt about the identity of this bee. The long face, three yellow bands and the white tail make it hortorum (there are no ruderatus in Scotland). B. terrestris has a short face, two yellow bands, and would normally have at least a hint of brown in the white.
This is one of the most common and widespread bumbles in Highland - see our maps live from NBN Gateway on http://www.hbrg.org.uk/MainPages/BeeAtlasUpdate.html (and http://www.hbrg.org.uk/Atlases.html will tell you how how to buy a copy!).

I understated my certainty on this one, but I am fairly sure of my ID. Lovely long face :)
