| The
identification of many solitary bees and wasps is frought
with difficulties and it took many months after
photographing this Cerceris rybyensis, before an
accurate identification was found. This is however, a
widespread species and preys on mining bees, which it
takes back to the nest. Nests are situated on the ground
and are dug by the female. We found several Cerceris
rybyensis resting on Thistle flowers in Sherwood
Forest during a rather dull early September 2008 day. The
very similar Cerceris arenaria, attacks large Weevils. |
