Description
Coptosoma scutellatum can reach a size of about 4–5 mm. These small true bugs are almost spherical or trapezoidal shaped and shiny deep black, sometimes with green, blue or bronze gloss. The side edges of the abdomen are yellow. The scutellum covers the abdomen and the tarsus is bipartite.
Distribution
This species can be found in most of southern Europe and it is widespread from North Africa to Siberia, China, Korea and Japan. In Europe it is missing in the British Isles.
It is one of the four European species of Coptosoma, most of other being restricted to Asia and Ethiopia.
Habitat
These thermophile bugs leave in dry and warm areas with moderately dense herbaceous vegetation, in lawns, limestones, clay and sandy soils. In the Alps, it is particularly common in the valleys, but can be found in good conditions up to 1000 meters above sea level.
Biology
They mostly feed on legumes (Coronilla species, Lathyrus species) and other leguminous plants, such as alfalfa (Medicago sativa), birdsfoot trefoil (Lotus corniculatus), milkvetch (Astragalus), vetch (Vicia), Sainfoin (Onobrychis), broom (Genista) or restharrows (Ononis).
The species overwinters as larvae (in third or fourth instar) and develops in May or June in the adult insect. The adults can be observed from Summer until September. The oviposition occurs in midsummer.
