Food: Leaves of host plants
Other notes: nymphaeae is usually larger and darker (on water-lilies); sagittariae is usually smaller and paler (on various semi-aquatic and terrestrial plants, especially docks Rumex spp and Rosaceae). Larvae and adults predated by Picromerus bidens and Zicrona caerulea (Heteroptera: Pentatomidae). In continental Europe, several ladybird (Coleoptera: Coccinellidae) species feed on eggs and larvae.
