Nomada marshamella is a bee from the family of Apidae . The species looksvery similar to Nomada fuscicornis .
features
The bees have a body length of 10 to 13 millimeters (females) or 8 to 13 millimeters (males). The head of the female is black and has red markings. The thorax is black and has yellow markings. The tergites are black and have yellow bands on the discs. On the first tergite and often also on the second, the ties are interrupted in the middle. The legs are red. Individuals from the south of the distribution area are often marked in yellow on the head. The third antenna segment is as long as the fifth and slightly shorter than the fourth. The labrum has a tooth near the front edge. The rails ( tibia ) of the hind legs are blunt at the end and have reddish, medium-length, small thorns. The males are similar to the females, but their heads are marked yellow and the antennae are more or less black at the top. The third antenna segment is shorter than the fifth. The posterior margins of the posterior tergites are more or less red.
Occurrence and way of life
The species is common in large parts of Europe. The animals fly from early April to early July. In Switzerland, the animals fly about a month later than north of the Alps. But you can still find them sporadically in October, which suggests a second generation. They parasitize Andrena assimilis , Andrena carantonica , Andrena eximia , Andrena ferox , Andrena rosae and Andrena trimmerana, and probably Andrena nigroaenea as well .
