One of three large species of Priocnemis with plentiful erect hair on the face and propodeum (subgenus Umbripennis). P. coriacea is unpredictable in its occurrence. Identification characters are given in Day (1988).
Widely distributed through southern and central England.
Scarce in central Europe, rare in northern and southern Europe (Wolf 1972).
Listed in Falk (1991) as Notable A.
Associated with lighter soils, on downland and thinly wooded heathland.
Univoltine; April to August, although Day (1988) records June as the latest date.
No prey recorded. However, it is probable that the wasps take larger species in the families Lycosidae and Gnaphosidae.
Little is known about this but Priocnemis in general use existing cavities within which they may excavate several cells (Day 1988).
Has been recorded at wood spurge, but may visit a wide range of plant species, as long as they have short corollae.
