Geschnbelte Kreiselwespe (Bembix rostrata)

Descrission:

These sand wasps need a lot of sand. In the park people do all sorts of sports a keep growth scarce. Bembix rostrata digs a 10cm diagonal duct (leading to the nesting chamber) and that very quickly with synchronized movements of their forelegs. The prey are flies of different sizes (here a big Syrphid I guess) that are fed to the larvae- sometimes up to 50 per larva - After every visit to the nest the opening is carefully closed i.e. pawed shut [Heiko Bellmann, 1999, translated].Phylum: Arthropoda (artrhropods, Gliederfer)Subphylum: HexapodaClass: Insecta (insects, Insekten)Subclass: PterygotaOrder: Hymenoptera (Hautflgler)Suborder: Apocrita (wasps, bees & ants; Taillenwespen)Superfamily: Apoidea (Bienen & Grabwespen)Family: Crabronidae LATREILLE, 1802 (kind of sand wasps, eine Familie der Sandwespen)Subfamily: BembicinaeGenus: Bembix (Kreiselwespe)Bembix rostrata FABRICIUS, 1781 (Geschnbelte Kreiselwespe)NE-Germany, Berlin: Hasenheide (parc), 11.08.2012 IMG_1948
