Andrena sp.
Members of the genus Andrena are mostly medium sized, abundant springtime bees. Some even emerge before all snow has vanished. Many species of Andrena are best identified by association with the flowers they pollinate. Nests are borrows in the soil, the entrance often hidden beneath a fallen leaf or other litter. Like any good homebuilder, the female waterproofs the walls of her brood cells, using a secretion from a gland in her abdomen.
Found sucking sap from Red Maple log with other insects.
