Calathus mollis (Marsham, 1802)

Description: A 6.5-9mm long pale brownish ground beetle, common in coastal sand dunes.

World Distribution: Distributed along coasts from southern Fennoscandia to the Iberian Peninsula and across the Mediterranean; therefore Mediterranean-Atlantic (91).

Irish Status: Locally abundant in sand dunes along the coast.

Ecology: Very xerophilous, and tied to a narrow zone of loose sand in the fore dunes on the east and south coasts of Ireland. However, on the more exposed north and west coasts it has a slightly wider range, wherever wind-blown sand occurs.
