Species text
Priocnemis gracilis is recorded widely in England and although previously regarded as a rarity, it is now known to be fairly frequent in Kent (Falk, 1991b). In Essex all records are from the Thames and Lee corridors except for one near Colchester. A good proportion of the British records seem to come from woodland on stiff clay soils, where the wasp is likely to be found in sunny rides, glades and clearings. Many other records are coastal, often from the disturbed ground of soft rock cliffs and landslips. It has also been taken on heathland and in sandpits. Priocnemis species usually excavate multi-celled burrows, often in natural cavities or the old burrows of other aculeates. These are stocked with spiders. Recent prey records are of an immature Clubiona (Clubionidae) and a salticid spider. Adults visit umbellifers such as Daucus. References
