Description
With Eucera spp. belonging to subgenus Synhalonia (as our locals do), males (e.g. above left) have very long, solid black antennae, and tan/yellow hair on clypeus (lower face). Females (e.g. above right) have a dark clypeus and shorter antennae. Eucera, larger than most Melissodes, have hair bands lacking or apical (not medial as in Melissodes). With Eucera, the clypeus projects outward, and the female abdomen is squared. Head is broad and flat-topped (versus Diadasia).
Nectar/
Pollen Plants
Generalists, often on lupine and manzanita.
Habits
These ground-nesters burrow into flat ground with side galleries of individual cells for each egg. Cells are provisioned with pollen and nectar and plugged with packed dirt. Burrows are about 1 foot deep.
Season
March to June
