Explanation of Names
Bembicinae Latreille 1802
3 tribes in the subfamily, with ca. 280 spp. in 35 genera in our area(1) and ~1700 spp. in >80 genera worldwide(2)
Mesonotum almost always expanded laterally into laminae more or less overlying the bases of the tegulae, and the jugal lobe of the hind wing is shorter than the submedian cell; all except Bembicini have two apical spurs on the middle tibiae; forewings with three submarginal cells.
most provsion lavae with Auchenorrhyncha but several species are kleptoparasitic on other Bembicinae
Life Cycle
Females are either solitary nest provisioners or brood parasites of other wasps. In the nest-provisioning species, female digs one or more ground nests using mandibles and front legs (often armed with a rake of stout spines called 'pecten').(3)
