Kleidocerys resedae Birch Catkin Bug Family: Lygaeidae Found throughout most of Britain, this rust-coloured bug is common on or around birch trees. The  forewings are patterned and largely transparent, with the corium and clavus punctate. The clavus has three rows of punctures. K. ericae is very similar, but slightly smaller and associated with heather on heathland. A darker form (privignus) occurs on alders, which is considered a distinct species by some authorities. This form is identified by the partly darkened clavus and uninterrupted dark streak on the hind margin of the corium, although intermediate specimens do occur. Adults overwinter and there are several generations a year, at least in the south. Adult: All year Length 4.5-5.5 mm
