Crossocerus bimaculatus LEPELETIER & BRULLÉ,1835; Crabro levipes (VANDER LINDER,1829); Crabro murorum (LATREILLE,1805); Crabro quadripunctatus (FABRICIUS,1793); Crabro quniquemaculatus (DAHLBOM,1838); Crabro rotundarius (DAHLBOM,1838)
Of the several Crossocerus species that nest in the soil, this is the only one with a boldly marked yellow gaster (but beware of specimens without spots). The spine at the bottom of the occipital carina is diagnostic for species recognition.
Widely distributed in Britain as far north as Ayrshire. Also northern, eastern and south-western Ireland and the Channel Islands. Records are concentrated within coastal areas and regions with sandy geology, producing a distinctly patchy distribution that excludes areas like the Cotswolds and much of West Wales. Abroad, found widely in west and south Europe and eastwards through Siberia to Mongolia (Lomholdt 1975-76).
