Trechoblemus micros (Herbst, 1784)

Description: A small (4mm) reddish-brown ground beetle of riverine floodplains, hiding in crevices on river and stream margins. Widespread but local.

World Distribution: A Eurosiberian Wide-temperate species (64) distributed across the whole of Europe into western Siberia.

Irish Status: Local and uncommon in lowland districts of the east, but possibly overlooked because of its subterranean habits.

Ecology: Recorded principally from the alluvia of riverine flood plains. It has also been pitfall-trapped on arable farmland, although this is probably a secondary habitat.
