Centrifugal wasp ( bembiX rostrata )
BembiX is a genus of wasps grave ( Spheciformes ) from the family Crabronidae. The globally widespread genus includes about 300 species. The main distribution area is in Australia with 80 species and the Ethiopian region with 90 species.

Features
The most important feature of the genus is the reduction of the middle point eye ( Ocellus ) to a narrow angular line. Only a few types, you can sense a lens. Other features are the reduction of palps on two labial palps and four Maxillarpalpen. Often, the labrum is elongated beak-like.
Way of life
The nests are on or multicellular, and it will also be built Mirage nests in some species, besides the actual brood nest. Eggs are laid either on the first prey or in the now empty cell. It is upright or lying on the ground, placed in the center of the cell or inclined similar to the rear cell wall. The brood is supplied with bees, wasps, botfly or antlion.
Since the nests are often located in society and the same places are populated over several years, the species of this genus are well researched.
