Andrena marginata

Andrena marginata is a species of the sand bee (Andrena) genus. It feeds on different nectar-bearing plants of the family Dipsacaceae, like Knautia arvensis and Succisa pratensis. The female builds a nest in the ground and fills the cells with a mixture of nectar and pollen. One egg is placed in each cell and the larva hatches, grow and pupates within the nest. The adults emerge in spring after hibernation.
