Tropidosteptes pacificus
Family: Miridae
A
medium-sized yellowish bug with rather transparent forewings. The
pronotum has a prominent pale collar, a pale unpunctured posterior
margin and two dark spots close to the anterior margin. The 1st
antennal segment is pale in both sexes; the remaining segments are
almost entirely dark in males but the 2nd segment is mostly pale in
females.
Adults and nymphs are associated with Ash Fraxinus and there may be more than one generation a year, since the species appears to have a long season.
Native to the USA and a recent arrival in Britain, first recorded in
2012 from the London area. Likely to be a horticultural
introduction, but natural spread from Holland, where the species was
first detected, cannot be ruled out.
Adult: June-September
Length: 4-5 mm
