Propylea dissecta is a species of lady beetle native to India, Sri Lanka, Bangladesh and Nepal. ^{[1] [2]}

Description

This robust beetle is about 5 to 6 mm in length. Elytra reddish orange in color with black central line. Adults show polymorphism with several intermediate and pale forms. ^[3]

Biology

Sexual maturity of male and female ladybirds is about 7 and 9 days respectively. Adult males are more willing to mate with females irrespective of age. Mating duration is longest amongst older adults where 30 day-old males and 20 day-old females can be found. ^{[4] [5]} Chemical signals as well as visual and tactile cues initiate male attraction toward females. Mating lasted longest about 275 minutes when it occurred between unmated individuals. ^[6]

It is a voracious predator on several aphids such as Aphis gossypii , Aphis craccivora , Lipaphis erysimi , Uroleucon compositae , Brevicoryne brassicae , Rhopalosiphum maidis and Myzus persicae . ^{[7] [8] [9] [10]}
