It was found to be composed of various heteropterans, lacewings, coccinellids
, ants and parasitoids (Lynch & Garner 1980; Boica Junior et al.

Among the predators maximum population of coccinellid
was observed followed by lacewing, wasp and spider.

Adaptations of Coccinella magnifica Redtenbacher, a myrmecophilous coccinellid
, to aggression by wood ants (Formica rufa group).
Individuals of this voracious species are larger than the average aphidophagous coccinellid
adults may survive on artificial diets with carbohydrate solution, but females will usually not lay eggs (Hagen 1962; Lundgren 2009), showing that this type of diet can affect insect fertility and fecundity.

Newly eclosed coccinellid
