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]

Coccinella transversalis, commonly known as the transverse ladybird or transverse lady beetle is a species of ladybird beetle found from India across southern and southeastern Asia to Malesia and Australia. It is not to be confused with Coccinella transversoguttata, a widespread species in Europe and North America also known as the transverse ladybird. The alternative vernacular of small transverse ladybird may be used for C. transversalis in instances where these two species are discussed together.

<i>Cheilomenes sexmaculata</i> Species of beetle

Cheilomenes sexmaculata is a species of ladybird. Although sometimes known by the common name of six-spotted zigzag ladybird, this is misleading as there are several colour morphs and some colour morphs of the species can be confused with Micraspis discolor and Chilocorus nigrita. The species has a wide distribution range within the Asian tropics and subtropical zones from India to Japan and parts of the Australian region. They have been introduced into the Caribbean islands as a biocontrol agent and their spread to South America was noted in 2019. It is well known as a predator of aphids and other small insects.
