Explanation of Names
'lover' + anthus
the common name "beewolf" refers to the habit of preying on bees
Females excavate cavities in soil to use as nests.
Hunting sites include flowers, natural bee nests and apiaries.
Adults feed on nectar, but larvae feed on bees provided by mother at time of egg-laying. Many species prey especially on sweat bees (family Halictidae
), but at least one European species favors honeybees (Apis mellifera
Provisions with bees or wasps(?), often Halictids (5)
The common "European" Beewolf is actually widespread virtually everywhere in tropical, subtropical and warm temperates regions, not only of Europe, but in Africa and Asia too.
While it does favor Honeybee (Apis mellifera) workers as preys, it sometimes takes mainly large-sized Halictus females where Honeybees are scarce. Indeed, presence of suitable soils (neither too sandy nor too clayish) in order to dig its long burrows seems more important than abundant Honeybees populations.
Another important factor is a warm, dry summer in the Northern limits of its range, like in my own Geneva region. There, it was much commoner during the late eighties and the nineties than nowadays; summer of 2001 was its last "good year" and it is now quite scarce. On the other hand, bee-keepers have many other things to worry and would certainly prefer numerous beewolves combined wiht colonies in good condition rather than the reverse.

Female beewolves cultivate bacteria in their antenna bases and apply to brood cells. These bacteria keep out potentially harmful bacteria. (Kroiss et al. 2010
