Nomada ruficornis (Linnaeus,1758)

Description and notes

One of the larger brown and yellow-striped Nomada species. Its presence should be checked wherever its host, Andrena haemorrhoa (Fabricius), is present. It is very similar in appearance to the very common Nomada flava Panzer, but rather darker generally, though not as dark as Nomada panzeri Lepeletier. The presence of a clear notch in the tip of the mandible will confirm this (the only other British Nomada with a bifid mandible is fabriciana (Linnaeus), which is smaller and red). Take care when handling live females, however; female Nomada have quite a robust sting!
