Life cycle of the leafcutter bee

Complete Metamorphosis

Leafcutters are solitary bees where the female takes care of all the work unlike the behavior of colony bees that are assigned a role per caste.  The female lays 35-40 eggs at a time inside nests created from leaves. 

They are filled with nectar and pollen for the larva to feed once hatched.  Pupation occurs over the winter with the adults beginning to emerge in spring and living up to two months.
