Abstract

The existence of polymorphs in the seven spotted ladybird beetle Coccinella septempunctata L. (Coleoptera: Coccinellidae) when analysed revealed five morphs collected in different seasons. These were predating on sucking pests infesting cotton and wheat. The morphological characters including male genitalia were studied in these. The abundance of various morphs revealed morph 1 with maximum abundance (73.3%), and the frequency of the melanic forms increased with the decrease in temperature.
