The rarest of our four Crossocerus species with yellow-marked gasters, and regarded as possibly extinct until its recent re-discovery in Hampshire and discovery in Wales.
Formerly found sparingly across southern England, from Dorset to North Lincolnshire. Now found in South Hampshire and Surrey, with a single record from Glamorgan (Crymlyn Bog). Abroad, reported across the taiga belt through Siberia to the Pacific Ocean (Lomholdt, 1975-76).
