Eysarcoris venustissimus, common name woundwort shieldbug, is a species of shieldbug belonging to the family Pentatomidae, subfamily Pentatominae.
Scientific name
The species was first named by Fabricius as Cimex melanocephalus.[1] However this name had already been used by Linnaeus for the mirid bug now known as Phylus melanocephalus - at the time, the genus Cimex encompassed the entirety of the Heteroptera. The replacement name Eysarcoris fabricii given by Kirkaldy in 1904 was used for many years, but Rider (1998)[2] pointed out the name venustissimus given by Schrank to what he called Schönste Wanze - most beautiful bug,[3] and this is now the accepted name.
Distribution
This species can be found in most of Europe.[4][5]
Description
Eysarcoris venustissimus can reach a length of 5–7 millimetres (0.20–0.28 in). These small bugs have a greenish-grey body. The head and the pronotum are copper coloured. They have a bronze-purple triangular stain at the base of the scutellum. The connexivum has black and white markings. The legs are whitish with black spots[6]
Biology
Eysarcoris venustissimus is an univoltine species. The larvae are visible from late June to October, while the new generation of adults appear from August through the following July.[7]
The nymphs feed on hedge woundwort (Stachys sylvatica), particularly the seeds, and on Lamiaceae species, especially on white dead-nettle (Lamium album).[6]
