P. discolor may be a synonym of P. sericea, since P. sericea with smooth pronota intergrade with P. discolor with wrinkled pronota. For a discussion, see J. Bratton & M. Greenwood 1997. British reed beetles, Plateumaris and Donacia (Chrysomelidae): an identification aid using pronotum surface characters. Latissimus 8: 11-14. However, the Atlas of British and Irish species (Cox 2007), the latest checklist (Duff 2012) and the recent AIDGAP key (Hubble 2012) all consider them to be different species with intermediate forms.
Palaearctic.
Biology
Status: Widespread and common
Habitat: Various wetland habitats, generally less acidic sites than P. discolor (usually seen on aquatic vegetation).
Host plant: Various wetland plants, but adults most often seen on bur-reeds (Sparganium spp.).
Overwintering: Unknown
Food: As larvae, probably at roots of various wetland plants. Adults found on flower heads, so may be pollen-feeders, at least in part.
Other notes: Separation from P. discolor may require dissection of males to investigate the aedeagus.

Palaearctic.
Biology
Status: Widespread and common
Habitat: Various wet habitats, usually more acidic than those favoured by P. sericea.
Host plant: Usually sedges (Carex spp.), sometimes other wetland plants
Overwintering: Unknown
Food: Adults on pollen of various plants, larvae at roots and rhizomes of cotton-grasses (Eriophorum spp.) growing among Sphagnum.
Other notes: Separation from P. sericea may require dissection of males to investigate the aedeagus.

Biology
Status: Widespread
Habitat: Various
Host plant: Usually hazel, sometimes other (generally small) trees.
Overwintering: Adults hibernate in leaf litter and similar.
Food: Underside of leaves of host plants.
Other notes: Scutellum pale (as dorsal colour). Similar to unmarked specimens of G. olivacea but the aedeagal tip of G. olivacea is asymmetrical in dorsal view and sharp/somewhat hooked in lateral view. In G. pallida, it is blunt, unhooked and symmetrical. In Britain, fully ovo-viviparous, producing fully developed 1st instar larvae.
