|A BIT ABOUT BUGS
Acompus species are small lygaeids, similiar in size and shape to Stygnocoris, but with at least the second and third antennal segments orange. The head and thorax are uniformly dark and adults are often brachypterous. Both British species feed on Valeriana or Valerianella.
In A. pallipes the middle and hind femora are dark and the length of the scutellum (A) is twice as long as the claval commisure (B) (see below). The fourth antennal segments are often pale. Compare A. rufipes.
Historically a great rarity and not seen after 1957 until 2019, when populations were discovered at several sites in west London, presumably following recolonisation from the continent. Macropterous adults were found in sparsely-vegetated grasssland in association with Common Cornsalad Valerianella locusta.
Adult: All year
Length 3.5-4 mm
