Andrena haemorrhoa (Orange-tailed Mining-bee)
This is one of a small group of Andrena species with the top of the propodeum strongly rugose. Females average a little smaller than a Honey Bee and are very distinctive with a very neat reddish pile on top of the thorax, a dull, slaty-black abdomen with bright orange hairs at the tip and yellow hind tibiae and tarsi.

Males have a rich-brown pile on top of the thorax and brownish hairs at the tip of the blackish abdomen. The hind tibiae and tarsi are mainly yellow.

This is a widespread and locally common species (scarcer in the north) which can occur in a wide variety of habitats. It flies from
late March into July and visits a wide variety of flowers, especially spring-blossoming shrubs, dandelions and umbellifers. Nesting occurs in dispersed aggregations in light soils, especially south-facing slopes and banks. Males often swarm around flowering Gorse and other small shrubs.
