Synuchus vivalis (Illiger, 1798)

Description: 6-8.5mm long black ground beetle living on open damp sand or gravel, usually near the coast but also in gardens inland. Widespread but local.

World Distribution: A Eurasian Wide-temperate species (65) distributed over the whole of Europe to Asia Minor and eastern Siberia.

Irish Status: Widespread but commonest in the east.

Ecology: A species of obscure ecology most often recorded, in Ireland, on sandy soils near the coast. Certainly not a common insect on high ground as was suggested by Johnson & Halbert (1902). There are records for upland peat in Antrim, but elsewhere it has been reported from such disparate sites as town gardens, wet forest litter and agricultural grassland. In Europe, it is known as an epigeal predator in winter wheat (Tolonen, 1995).
