Nomada rufipes (Cavenham Heath NR)

I have added a couple of photos of this cuckoo bee checking out other bees homes , which it will lay eggs in and use the stores meant for the other bees young.

This is a medium-sized cleptoparasitic bee which is yellow and black, although some females may be red, yellow and black. The bees can be very obvious on some heathland sites, being more readily found than their hosts (bees of the Andrena denticulata group)
