About Dysdercus koenigii
This species, Dysdercus koenigii, has the following life stage and morphological characteristics. Nymphs moult five times during growth. First and second instar nymphs are orange to red. Third instar nymphs develop emerging wingpads; they are orange when first moulted, and their colour deepens by the second day. The fourth instar is crimson, cylindrical in shape, and has larger, darker wingpads. The fifth instar is similar in appearance to the fourth, with prominent dark wingpads, plus black antennae and black legs. Adult Dysdercus koenigii are also crimson, with a pair of black spots on their forewings. When the insect is at rest, the membranous hind wings are concealed underneath the forewings. Males reach about 14 mm (0.6 in) in total length, and females are slightly larger than males. Dysdercus koenigii is commonly distributed in India, Pakistan, and southeastern Asia.
