Identification

Hairy-banded mining bee is an easily recognized, late season, mining bee. It occurs in the United States from Maine to Idaho south to Tennessee and New Mexico, and in Nova Scotia, Quebec, and Ontario, Canada. It is common in Minnesota. It appears in late summer when its preferred pollen sources, Solidago and Euthamia, are in bloom.

Hairy-banded mining bee is often mistaken for a bumble bee. Females are 716 to ½ (11 to 13 mm) long. Males are more slender and a little smaller, 516 to (8.5 to 10 mm) long. Both sexes are densely covered with long hairs that are lemon-yellow with a slight greenish tinge.

There are two large compound eyes on the sides of the head and three simple eyes (ocelli) in a triangle on top of the head. The compound eyes are distinctly vertical. The inner margins are straight up and down and close to parallel. Next to the inner margin of each compound eye there is a slight depression (fovia) out of which emerges a dense band of pale hairs. The face is wider than long. The tongue is short and pointed. The finger-like sensory organs (labial palps) attached to the mouth have four segments. All of the segments are cylindrical and about the same length. The antennae of the male has 10 segments (flagellomeres) beyond the scape and pedicel. The female has 11 flagellomeres. There are two grooves (subantennal sutures) below the base of each antenna, though these cannot be seen without careful handling and possibly also a microscope.

The exoskeletal plate covering the first segment of the thorax (pronotum) is short and collar-like. There is a rounded lobe on each side of the pronotum that does not reach the small plate covering the wing base (tegula). The plate on the upperside of the large middle segment (mesonotum) is entirely black with no yellow markings.

The female has six abdominal segments, the male has seven. The abdomen of both sexes is black with no yellow markings but with a dense band of erect yellow hairs at the rear margin of each segment.

The forewings are mostly clear but moderately darkened toward the tip. The marginal cell is relatively long and is pointed (narrowly rounded) at the tip. There are three submarginal cells. The second submarginal cell is much shorter than the first and third. The basal vein is nearly straight. The broad lobe at the base of the hindwing (jugal lobe) is longer than the narrow cell adjacent to it (submedian cell).

Life Cycle

The female creates a vertical tunnel in the ground with side tunnels branching off. Each side tunnel is a cell containing a single egg and provisioned with a ball of pollen mixed with nectar.

Glossary

Flagellomere

A segment of the whip-like third section of an insect antenna (flagellum).

 

Ocellus

Simple eye; an eye with a single lens. Plural: ocelli.

 

Palp

Short for pedipalp. A segmented, finger-like process of an arthropod; one is attached to each maxilla and two are attached to the labium. They function as sense organs in spiders and weapons in scorpions. Plural: palpi.

 

Scape

On plants: An erect, leafless stalk growing from the rootstock and supporting a flower or a flower cluster. On insects: The basal segment of the antenna.

 

Scopa

A brush-like tuft of hairs on the legs or underside of the abdomen of a bee used to collect pollen.

 

Tegula

A small, hardened, plate or flap-like structure that overlaps the base of the forewing of insects in the orders Lepidoptera, Hymenoptera, Diptera, and Homoptera.
