Marsham's Nomad Bee

Nomada marshamella is a large (10-13mm) black and yellow nomad bee with a rather wasp like shape. It has well separated yellow spots on the second tergite with no reddish fringes on the tergites which are seen in similar species. The sternites are mostly black and yellow in colour with little or no red, the tegulae are orange. Male N. marshamella are difficult to identify when compared to N. fulvicornis but the yellow markings on the eye and tergite 1 are less extensive, there is some brown on the tegulae and it has longer antennae. It has a black head which is marked with yellow in males, which are smaller than the females.

Nomada marshamella is endemic to the western Palearctic ecozone from Britain and Ireland in the west east to Turkey, north to southern Finland and on the islands of Corsica and Malta.
