The psenini are a tribe of digger wasps (Spheciformes) from the Crabronidae family .
features
Compared to the other tribes of the subfamily Pemphredoninae , the psenini are at the base of the family tree and have many original features. They are small to medium in size and 4 to 15 millimeters in length. The smallest species belong to the genus Ammopsen . In all species the first sternite of the abdomen is shaped like a stalk, it forms a petiolus , which can be very short in ammops . Three submarginal cells are visible on the forewings, in the related tribe Pemphredonini the wing veining is reduced, with only one or two submarginal cells. The males have 13 antenna segments, the females 12.
distribution
The species of Psenini are distributed worldwide, but the main distribution area is in the Holarctic and Oriental . Around 455 species in 11 genera are known worldwide, while in Europe there are 33 species in five genera. Four genera with 19 species also occur in Central Europe.
Way of life
The tribes are distinguished from the Pemphredonini mainly by their prey. In the genera Psen , Mimesa and Mimumesa , the females hunt small cicadas from the families of the dwarf cicadas (Cicadellidae), blood cicadas ( Cercopidae) and humpback chirps (Membracidae), the genus Psenulus either hunts aphids or leaf fleas , as do the females of the Pemphredonini.
