Chrysolina oricalcia belongs to the subfamily Chrysomelinae, tribe Doryphorini.
Europe (missing on the Iberian Peninsula), east to Ukraine and Turkey; Siberia?
Wet tall forb communities, humid forests and clearings near streams.
In Central Europe often in montane or submontane regions, in Northern Europe only in the lowlands.
Length 6 - 9 mm; short-oval species; upper side bronze-coloured, sometimes blue or green; elytra with distinct rows of dots; pronotum mostly smooth or very finely dotted; sides of pronotum straight, strongly converging to the front; side edges of pronotum set off from base by a sharp notch.
Chrysolina oricalcia is a predominantly crepuscular and nocturnal species that lives oligophagous on various umbellifers (Apiaceae), especially on cow parsley (Anthriscus sylvestris). Other host plants are Chaerophyllum, erect hedgeparsley (Torilis japonica), Cicuta virosa, hemlock (Conium maculatum) and ground elder (Aegopodium podagraria).
Chrysolina oricalcia hibernates as imago. The females of the ovoviviparous species give birth to their larvae in early spring. In ovoviviparous animals the embryos develop in eggs which remain in the mother's body until hatching. The embryos feed on the yolk contained in the egg (yolk sac). The larvae develop in 3 - 5 weeks. They pupate in an earth cave in the ground. After about 3 weeks the new generation hatches, which is active from July to September and then disappears for hibernation.
