[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 seniority of the name venustissimus, given by Schrank in 1776 (Schönste Wanze, most beautiful bug).

The legs are whitish with black spots[7] Stagonomus venustissimus is a univoltine species.

The larvae are visible from late June to October, while the new generation of adults appear from August through the following July.

[8] The nymphs feed on hedge woundwort (Stachys sylvatica), particularly the seeds, and on Lamiaceae species, especially on white dead-nettle (Lamium album).
