Seven aphid species (Eucalipterus tiliae, Tuberculatus annulatus, Euceraphis betulae, Cavariella konoi, Acyrthosiphon ignotum, A. pisum, Macrosiphoniella artemisiae) were tested as prey for larvae of Anatis ocellata and all were essential prey. Nine aphid species (Chaitophorus tremulae, Cavariella konoi, Aphis farinosa, Eucalipterus tiliae, Euceraphis betulae, Macrosiphoniella artemisiae, Acyrthosiphon ignotum, Aphis spiraephaga, Aphis fabae) were tested as prey for Calvia quatuordecimguttata. The former six species were 'essential' food, while the latter three aphid species were unsuitable food for C. quatuordecimguttata. The experiments were conducted under laboratory conditions with no choice of prey. Some of the checked 'essential' prey apparently do not represent food in the field as they occur in other habitats than the studied coccinellid species that are common on trees.
