During the last couple of days I have taken Volucella bombylans, apparently nectaring, on both Comfrey and White Dead-nettle. The flowers have relatively long corolla tubes. Does V. bombylans have a longer tongue than most Syrphidae? Are other Syrphids able to exploit this type of flower?

I don't think V bombylans has a particularly long tongue, so your observation is very intriguing. Even some Bombus bees cannot reach the nectary and have to resort to puncturing the side of the flowers to "rob" the nectar.
