Amara communis (Panzer, 1797)

Description: A common 6-8mm brassy Amara occurring in moss and litter very widely, also in upland peat. Phytophagous.

NI account: Widespread and fairly common in northern counties but status elsewhere difficult to gauge at present.

Ecology: Eurytopic and recorded from agricultural land, lightly wooded areas and occasionally on drier Calluna heaths in the hills.

Distribution: A Eurasian Boreo-temperate species (55) found across Europe, south to the Caucasus, and east across Siberia to Kamchatka. Introduced to North America (Bousquet, 1992).

Similar Species: Difficult species to characterise - similar in appearance and size to the following. A. aenea: elytral intervals nearly flat A. convexior: lateral rows of deep punctures on elytra without a significant gap in the middle A. plebeja: basal pore puncture on scutellar striae; terminal spur of pro-tibiae trifid A. familiaris: legs entirely pale A. lunicollis: only one or two basal segments of antennae pale

Key Identification Features:

  • Body stout and a characteristic 'oval' shape
  • Head with two supra orbital punctures
  • Elytra lacking pore-puncture at base of scutellar stria
  • Terminal spur of pro-tibia simple
  • Hind angles of pronotum simple
  • Antennae with 3 (or 4) pale basal segments
  • Femora dark
  • Elytral striae deepened towards apex, intervals convex
  • Lateral rows of elytral punctures with a gap in the middle (Fig. 87- view elytra from side)
