The male has narrow light tergite bandages, yellow face and normally hairy middle legs clearly visible in the field.

Both genders have olive green complex eyes and one very high, clearly perceptible flight sound.

[3] A. bimaculata have been spotted in North Africa from Morocco to Libya; a report by FRIESE (1915) from Eritrea is questionable.

They also live from Portugal through southern, central and eastern Europe, Ukraine and southern Russia to eastern Siberia (Central Baikal) and across Asia Minor and the Caucasus to Iran and Kyrgyzstan; north to Central England (allegedly also recently detected in Ireland), Denmark, Latvia, Kirov; south to Sicily (also on Corsica, no evidence from Sardinia), Albania, Bulgaria (no evidence from Greece, Israel and Iran).

[4] A. bimaculata nests in sandy areas of lower locations: inland dunes and fields of drifting sand, sand pits, sandy embankments, ruderal areas, forest edges, and forest clearings.

Their known pollen sources are, in Asteraceae: Centaurea scabiosa, Centaurea stoebe, Cirsium vulgare, Picris hieracioides, Hypochoeris radicata; in Boraginaceae: Echium vulgare, Anchuso officinalis; in Campanulaceae: Trifolium arvense; in Hypericaceae: Hypericum perforatum; Lamiaceae: Teucrium scorodonia; in Lythraceae: Lythrum salicaria; and in Rosaceae: Potentilla incana.

The field observations also showed that the flower visits on a pollen-collecting flight are randomly strung together, depending on the offer.
