Anisodactylus binotatus (Fabricius, 1787)

Description: A 10-13mm long, dull black, phytophagous ground beetle of open grassland, usually near water but sometimes on arable land. Local and rare.

World Distribution: A Eurosiberian Wide-temperate species (64) found over most of Europe, south of 62°N, north Africa, Asia Minor and western Siberia.

Irish Status: Very local and rare in recent times, at least in northern counties, but widespread. May be retreating westwards, at least in the northern half, where, despite intensive recording, there are no recent records for eastern counties.

Ecology: A hygrophilous species recorded more frequently from western Ireland than elsewhere in recent decades. Usually found on rushy pasture or riverbanks on heavy clay or peat soils.
