Pierre RasmontAtlas of the European Bees: genus AmegillaFirst on line 29.VIII.2014, updated 5.XI.2014, 19.II.2016
The genus
Amegilla includes around 260 species all over the world. It includes 36 species in West-Palaearctic region.
Like other Anthophorini,
Amegilla are all solitary species, most of them digging their simple nest in dry ground, giving their English name "digger bees". While some
Anthophora and
Habropoda could be sometimes seen in woody areas,
Amegilla are clearly associated with arid or subarid biomes, matorrals, steppes, sub-deserts and deserts. Very few species cross the 45th parallell to the north and only in very isolated places.
Like
Anthophora, they are foraging mainly flowers with long corollae, as Boraginaceae, Lamiaceae, Leguminosae, Scophulariaceae and Compositae from the Carduae tribe (thistles).
All species are very fast flyers. Some taxa are nearly impossible to catch because of their incredible agility. For these reasons, it is clear that their abundance and distribution remain underestimated. Beside, some species are not easy to identify. A lot of taxa are known just by few specimens.
Because of their relative scarcity in collection and their shape and colour homogeneity, their taxonomy remains quite confuse.
Amegilla have been included in
Anthophora during long time. As fundament, one should use the revision of Friese (1897) (under the name
Podalirius) and Brooks (1988). This last one only dealing with a detailed generic and subgeneric classification. Several other papers could help: Priesner (1957) for Egypt and adjacent countries mainly N. Africa (under the name
Anthophora), Iuga (1958) for Romania and adjacent countries, Osychnyuk (1978) for the European part of former USSR, Herrero & Pérez-Iñigo (1982) for Iberian peninsula. As for
Anthophora, one cannot avoid to consult a bunch of small other papers to assume the identification of some species.
The genus
Podalirius, as promoted by Friese (1897) was lumping alltogether
Amegilla,
Anthophora and
Habropoda. I stick here instead with the generic and subgeneric classification of Brooks (1988) and Michener (2001, 2007). The West-Palaearctic tribe Anthophorini includes so the genera
Amegilla,
Anthophora and
Habropoda (that Brooks placed in a separate tribe).
This first very provisional version only includes the full checklist of West-Palaearctic species and maps that just point out countries. For some species, it also display very preliminary detailed maps.
Because of the extreme difficulty to approach
Amegilla, there are very few photographs of living specimens available.
