Anthophora terminalis (Orange-tipped Wood-digger bee)

Taxonomy
Anthophora is a genus in the family Apidae. The Apidae family includes honey bees and bumble bees. There are very few Apidae species that nest in wood or stems; most are ground nesting.
Description
Anthophora terminalis is a fairly robust and hairy bee with dark integument and grey to yellowish hairs. The males have yellow on their faces. Like all bees in the Apidae family, they carry pollen on hairs on their back legs.
Nest Structure
Nesting reports of Anthophora terminalis, including the Bee Atlas nest, indicate that this species uses sawdust or chewed wood to form the partitions and plugs of their nests. A. terminalis is often reported to partly or fully excavate its own nests.
Hole Sizes
The MN Bee Atlas nest was found in a 6.25 mm diameter tunnel.
Medler (1964) reported on Anthophora terminalis in Wisconsin and found that it nests in 1/4-5/16 in. (6.25-7.8 mm) holes.
Voltinism
Anthophora terminalis is univoltine in North America as far as we know (Cockerell, 1903; Medler, 1964). Our Bee Atlas nest emerged the following spring.
Activity Period
We do not have information about when the Bee Atlas nest was made. The nest was far back in the tunnel and short, making it hard to see the nesting activity. Cockerell (1903) and Medler (1964) suggest the bee is active in mid to late summer.
