Those feeding on coccids are coccidophagous and people feeding on fungi are the mycophagous kinds.

The ladybird beetles are worthy of exclusive reference in literature as very well as in the beliefs of persons of different nations. They are frequently worried with harbingers of good fortune. The morphology of all ladybird beetles is a lot more or much less comparable. They are compact to medium sized beetles. The body is covered by elytra which are carved with strips or spots.

Aphis nerii is deemed to be unsuitable for several species of ladybirds as it includes some toxins which declines the population of these bugs but Cheilomenes sexmaculata when fed on this aphid confirmed enhancement. Aphids variety the vital foods of this beetle as they sustain oviposition as perfectly as proper progress of overall body but they are readily available only for a quick interval.When the availability of aphids declines the beetle switches by itself to other foodstuff supplies like psyllids, whiteflies, mealybugs, tingids, leaf- and plant hoppers, mites, and early instar lepidopteran larvae.
