Description and notes
A very bright, black and yellow cuckoo bee and one of the largest of our Nomada species. In common with its hosts (Andrena species of the nigroaenea-group) this is a very widespread and frequently found species, often seen flying over short vegetation and bare ground in sunny places during the spring and, in smaller numbers, late summer. These later dates support the supposition that its hosts may also have a later flight period than has been previously recognised.
Over most of the British Isles, although there are few Scottish records. It is also listed from Ireland (Stelfox, 1927; O’Connor et al., 2009).
It is widely distributed in Europe.
