Description

The mean body length is about 2.97 mm. Some specimens rarely have pronotal and elytral spots and mostly lack the pronotal and sub scutellar spots. The form testaceus is without any markings. It has bright golden yellow to reddish brown body and sometime dark brown in color.[1][4]

Eggs are spindle shaped and pale yellow. The incubation period is about 4 days. There are four instar larval stages. The total larval period is about 10 days. The pre-pupal and pupal period is about 1.5 and 7.8 days, respectively. Total life cycle is about 50 days by male and 55 days by female.[5]

Biology

It is a predator of several whiteflies, aphids and scale insects such as Aphis craccivora, Aleurodicus dispersus, Aleurodicus dispersus, Aphis fabae, Aphis nerii, Aphis malvoides, Pseudococcus, Aphis spiraecola, Hysteroneura setariae, Melanaphis sacchari, Lipaphis erysimi, Pentalonia nigronervosa, Rastrococcus iceryoides, Ferrisia virgata, Toxoptera odinae and Chloropuluinaria psidii.[1][6][4]
