Reaction of ants to, and feeding biology of, a congeneric myrmecophilous and non-myrmecophilous ladybird
Journal of Insect Behavior 22 (3), 173-185
Abstract: Coccinella magnifica Redtenbacher lives only in close contact with species of the Formica rufa group. Laboratory experiments were set up to determine how this species may be adapted to living with ants by comparing its behaviour with that of the closely related Coccinella septempunctata L. Eggs and larvae of C. magnifica placed on the foraging trails of ants were bitten significantly less often by the ants than those of C. septempunctata. However, the ants responded similarly to the adults of both species. For these two species, the presence of ants resulted in a significant decrease in predation efficiency. However, C. magnifica was more efficient at catching aphids in the presence of ants than C. septempunctata. The behaviour of this myrmecophilous species is discussed by taking into account that it is a generalist in terms of prey specificity.
