Deraeocoris flavilinea

Deraeocoris flavilinea is a species which has rapidly colonised the UK following its arrival in 1996 and is now widely established and common across south and central Britain at least. The host-plants are sycamore and field maple, although it may frequently be encountered on other trees and shrubs.

Deraeocoris flavilinea is a large and fairly distinctive bug, but sexually dimorphic and thus rather variable. Males are much darker than the more orange females, and the front and rear margins of the pronotum are narrowly pale. The cuneus is variable and the sides of the scutellum paler in both sexes.

Seen in the gardens of Chiswick House in July 2023.
