Females of this species have a very distinctive neat reddish pile on top of the thorax when fresh, a dull slaty-black abdomen that is almost bare except for bright orange hairs at the tip, and yellow hind tibia and tarsus. The males have a rich-brown pile on the thorax and buff-brown hairs at the tip of their blackish abdomen. The hind tibia and tarsus are mainly yellow. Andrena haemorrhoa is another widespread and common species, particularly across southern counties, where it can be found from late March into July in a variety of habitats. Nesting occurs in dispersed aggregations in light soils, especially on south-facing slopes and banks.

As of May 24, the NBN Atlas had Andrena haemorrhoa alongside Andrena ovatula as the third most frequently recorded Andrena species in Dorset.
