Status: Very local, a few sites in East Anglia only. Rare (RDB3)
RDB Category: Rare (RDB3)
Habitat: Various
Host plant: Flixweed, Descurainia sophia, though woad (Isatis tinctoria) should also be checked as this is a host in continental Europe.
Overwintering: Unknown.
Food: Adults on leaves, larvae are miners in pithy stems.

Status: Fairly common in England, sparse in Wales and Ireland, one old record from Scotland.
Habitat: Various
Host plant: Viburnum spp.
Overwintering: As eggs in cavities chewed into stems of host plants and covered by a hard, dried cap of mucus and faeces or regurgitated food.
Food: Adults and larvae both on stems and leaves.
Other notes: Predated by several species of pentatomid shieldbug; eggs predated by the ant Myrmica sabuleti and damaged by the mite Thyreophagus entomophagus. Adults eaten by coal tit and bullfinch. Eggs parasitised by severl hymenopteran species. Adults infected (fatally) by the fungus Beauveria bassiana.

Status: Widespread around coasts
Habitat: Sand dunes, less often on roadside verges
Host plant: Sea rocket (Cakile maritima) and other Brassicaceae
Overwintering: As adults
Food: Adults on leaves, larvae are leaf- and stem-miners
Other notes: Similar to P. chrysocephala ssp. anglica but has distinct front angles on the pronotum, coarse punctures on top of the head (compared to those between elytral striae) and 1st front tarsal segment narrower than the 3rd in males.

Status: Very localised in central southern England (as far north as Derbyshire), with most records from Oxfordshire. It may have become more widespread since the late 1980s but this requires confirmation (hence RDBK status)
RDB Category: Insufficiently Known (RDBK)
Habitat: Various
Host plant: Various cereals and wild grasses; also trees and shrubs.
Overwintering: As larvae, then probably as adults the year after.
Food: Adults inside wheat seeds and one developing leaves/sheaths (they can create bare areas in fields and skeletonise oak leaves); larvae probably at the roots of grasses.
Other notes: Adults parasitised by a braconid wasp (probably Perilitus sp.), a nematode, and numerous mites (all unidentified).

Status: Widely scattered
Habitat: Various
Host plant: Common reed (Phragmites australis), various trees, and cultivated cereals; possibly other plants.
Overwintering: As adults in moss, grass tussocks and rotten bark.
Food: Adults on leaves, larvae probably at roots.
Other notes: With teneral specimens, take care to avoid confusion with P. luteola.
