Status: Scarce (Notable A), though could more accurately be considered RDB2 (Vulnerable). Also a UKBAP species.
Habitat: Fens, banks of rivers with wide floodplains
Host plant: Tansy (Tanacetum vulgare) and Water Mint (Mentha aquatica)
Overwintering: Unknown, although some individuals undergo an extended diapause of more than a year.
Food: Leaves of host plants.
Other notes: Very similar to C. herbacea, but suture metallic blue or blue-green and darker than the elytra.

Status: Widely distributed.
Habitat: Various, especially where damp; also woodland rides.
Host plant: Various Lamiaceae; also on nettles
Overwintering: Usually as a prepupa, although adults and larvae may also be able to overwinter.
Food: Adults and larvae feed on leaves of host plants.
Other notes: Larvae feed at night and hide in seed capsules during the day.

Status: Widespread, especially in England and Wales
Habitat: Various
Host plant: Usually St.John's-worts (Hypericum)
Overwintering: Adults do overwinter, although most die by February.
Food: Adults feed on Hypericum leaves & flowers; larvae feed on leaves and stems.
Other notes: Pronotum and elytral interstices dull and very finely punctured. Elytral striae formed of sparse punctures.

Status: Widespread in England and Wales.
Habitat: Various
Host plant: Usually St.John's-worts (Hypericum); occasionally others such as ragworts, though probably accidentally.
Overwintering: Unknown location, but adults do overwinter.
Food: Leaves of St.John's-worts (Hypericum)
Other notes: Head metallic green. An alternative colour form is entirely golden-green and may appear quite dark. Pronotum and elytral interstices coarsely punctured and shiny. Elytral punctures form fairly faint, sometimes partly irregular, striae among the smaller interstitial punctures.

Status: Common and widespread.
Habitat: Various
Host plant: Various, but especially noted on creeping buttercup (Ranunculus repens)
Overwintering: Adults hibernate from autumn to April in a variety of locations.
Food: Various, but especially noted on leaves of creeping buttercup (Ranunculus repens)
Other notes: Similar to C. banksi, but usually smaller. Elytral punctures dense and random, sometimes forming a partial row along the suture, especially in the rear half.
