Eremocoris fenestratus
Family: Lygaeidae

Eremocoris are medium-sized or large ground bugs which have rather reddish-brown forewings and a pair of semicircular white spots on the membrane, adjacent to the cuneus.

E. fenestratus has
one large and several smaller spines on the front femora. The hairs on the hind tibiae are roughly equal to the tibial width (shorter in E. abietus). The upperside is rather shiny.

Historically known only from the Chilterns, where it was associated with juniper, this species was thought to be extinct before reappearing in the London area in 2010. The bugs were found under cypresses and are probably the result of horticultural introduction from the continent.

Adult: All year
Length 6.0-7.5 mm
