Status: Not threatened, but may have declined outside southern England.
Habitat: Various open habitats
Host plant: Bedstraws (Galium), crosswort (Cruciata laevipes) and woodruffs (Asperula)
Overwintering: Adults may be buried in winter; they may be active during mild winter periods.
Food: Adults and larvae feed on leaves and stems of bedstraws
Other notes: Random, dense, moderately-sized punctures. After rounded side angles, pronotum constricts less sharply than in T. tenebricosa. Superficially similar to Chrysolina violacea, but this has orange-brown tarsi and palpi (with tarsi usually much paler than the rest of the legs - femora and tibiae are metallic purple).

Status: Rare, listed as RDB2 'Vulnerable'
Habitat: Wet heathland, bogs, moorlands and commons
Host plant: Cross-leaved heath (Erica tetralix); may be found on other nearby plant species, though probably accidental.
Overwintering: Unknown
Food: Cross-leaved heath
Other notes: Very similar to C. bipunctatus var. thomsoni and requires close examination to separate them. Historically, a number of records of C. biguttatus have been shown to actually be C. bipunctatus var. thomsoni. Easily distinguished from the common form of C. bipunctatus. See Mann & Barclay (2009) and the correction on p.38 of The Coleopterist 19(1) (2010) for more on this.

Status: Scarce (Notable B); widespread but very local.
Habitat: Various
Host plant: Various
Overwintering: Unknown
Food: Various
Other notes: The uncommon form (var. thomsoni) is black with only the tips of the elytra orange and requires close examination to separate it from C. biguttatus. The usual colour form is easily distinguished from C. biguttatus.

Status: Widespread but Scarce (Notable B)
Habitat: Various, but especially lightly grazed grassland.
Host plant: Various, usually yellow flowers, sometimes other plants.
Overwintering: Unknown
Food: Adults feed on pollen of host plants.
Other notes: Longer (usually) and with coarser pronotal punctures than the similar C. hypochaeridis.

Status: Scattered with clusters in some limestone and dune areas.
Habitat: Various open habitats
Host plant: Various, usually yellow flowers
Overwintering: Unknown
Food: Various
Other notes: Shorter (usually) and with finer pronotal punctures than the similar C. aureolus.
