Sciocoris cursitans
Family: Pentatomidae

The only representative of the genus in Britain, this pale brown shieldbug has a distinctively broad and laterally expanded connexivum and a very rounded head. Males are able to stridulate loudly.

Overwinters as an adult, mating and laying eggs in the spring. Larvae (June-August) are similar in shape to adults, but have two pale patches on the abdomen with a black spot at each end. They are associated with mouse-eared hawkweed and Potentilla species, which are thought to be the hostplants.
The new generation of adults is complete from August onwards.

Scarce and locally distributed across southern England, in sandy areas and warm, sheltered slopes on calcareous grassland.
