Deraeocoris flavilinea - A Mirid Bug
Deraeocoris flavilinea Family Miridae
Length 7-8 mm
A new coloniser entering circa 1996, and is now widely established and common across south and central Britain at least.Host-plants are sycamore and field maple, although it may frequently be encountered on other trees and shrubs.
D. 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.
The tibial banding pattern is shared by D. olivaceus, which is brick red in colour, similar to female flavilinea. However, this uncommon species is larger, has long hairs on the sides of the pronotum and is associated with hawthorn.
