Pachybrachius fracticollis
Family: Lygaeidae

This genus is recognized by the characterstic shape of the pronotum, which is strongly constricted behind the middle. The sides of the pronotum are not thinned to produce keels.

P. fracticollis is distinguished from the extrememly rare P. luridus by the short pubescence on the pronotum (long and erect in P. luridus) and by the single row of spines on the front femur (a double row is present in P. luridus).

Distributed locally and patchily across England and Wales, inhabiting bogs, fens and wet heathland, frequently in association with cotton grass, bog myrtle and various sedges.
