Micraspis discolor is a species of ladybird. ^[1] It was described by Johan Christian Fabricius in 1798. ^[2] It is widespread throughout Asia, North America and parts of Oceania.

Distribution

It is found in Bangladesh, China, India, Malaysia, Sri Lanka, Taiwan, Vietnam, United States, Hawaii and Tonga. ^[3]

Description

Body length is 5 to 6 mm. Adult has a reddish orange body which is oval in shape. There are black stripes on elytra. ^[4]

Biology

It is one of the most common lady beetle found in rice ecosystems particularly during flowering and feeds on pollen. ^{[5] [6]} The species can be used as a bio-control agent for brown planthopper. It is found as both entomophagous and phytophagous species of beetle. ^[7]

Both adult beetles and nymphs are voracious predators on several pests such as, Aphis craccivora , Aphis gossypii , Aphis spiraecola , Leptocorisa acuta , Myzus persicae , Nephotettix cincticeps , Opisina arenosella , Pentalonia nigronervosa and Sogatella furcifera . ^{[3] [8] [9] [10]}
