Adults
fly in March to May. Nists in large colonies of up to several hundred
single nests. The nests are made in sandy soil, preferrably near flood
plains, because the animals only feed on Salix trees and also supply
their nests exclusively with Salix pollen. The females close the entry
of their nest with sand everytime they leave to collect pollen. This is
obviously a protection against their parasite, the bee Nomada
lathburiana, that patrol the colonies in large numbers waiting to enter
an unguarded nest.
