Their first tergite is spotted black or yellow, the third antennae of the females is at most slightly longer than the fourth and the antennae of the males are only slightly widened and have short hairs.
Occurrence
The species occurs in Europe and Asia as far as Korea. It colonizes open sandy habitats, but it can also be found in settlement areas, for example in the sand joints of paving stones. The animals fly from late May to mid-September. The species is rare in Central Europe in the south and common in the north.
Way of life
The females of Crabro peltarius lay their nests up to 28 centimeters deep in the sand. The sand is pushed out of the hole with the hind legs and abdomen. Up to seven cells are created in the nest. Under good conditions, the females build their nests side by side and form aggregations. The males spend the night in the dead wood, with up to five individuals spending the night together. The brood is supplied with 9 to 16 flies of different species. These are hunted on trees and bushes. The species is parasitized by Myrmosa atrata .
