Dock Bug
Coreus marginatus
The dock bug (Coreus marginatus) is the most common European member of the leaf-footed bug family (Coreidae). Its flattened, leathery body measures 11–16 mm in length and features speckled brown or grayish-brown camouflage coloration. Key identifying traits include a broadly expanded, slightly upturned abdomen and two tiny projections located between the bases of its thick, four-segmented antennae. Beneath the wings, the upper abdomen is bright orange. This species is widespread across meadows, wastelands, forest edges, and gardens from April to late autumn. Both nymphs and adults feed on plant sap, primarily from docks and sorrels, as well as brambles and raspberries in gardens. When threatened, it releases a pungent defensive fluid. It overwinters as an adult hidden in leaf litter.
