Females are easily recognised by the broad hind tibiae with a very short dorsal hair fringe coupled with the largely glabrous abdomen bearing white hair fringes along the hind margin of tergites 2-4. Males resemble small slim females and can be distinguished from species like wilkella and ovatula by the dark hind tibiae and longer hind tarsi, which are about 1.5 times the length of the tibiae.
The spring generation forages heavily on spring blossoming shrubs and spring umbellifers, whilst the summer generation likes brambles, summer umbellifers, thistles and ragworts.
The spring generation flies from March to May and the summer generation from July to September.
A. dorsata is widespread and locally common in southern England. It is now thought to be expanding its range northwards with records extending north to Lincolnshire and has also been recorded in South Wales.
Rare in VC55 - this species had not been recorded in Leicestershire and Rutland since the early 1900s until the Sapcote record of March 2014.
