Life Cycle of Spined soldier bug
Egg The eggs of spined soldier bug are typically barrel-shaped and clustered. Initially, they exhibit a uniform pale color that darkens as embryonic development progresses. They repose stationary until hatching.
Nymph Upon hatching, the nymph resembles a miniature, wingless adult spined soldier bug. Changes include gradual enhancement in size, development of wing pads, and variation in coloration with each molt, passing through several instars.
Adult Emerging from its final molt, the adult spined soldier bug exhibits fully developed wings and functional reproductive organs. There's notable sexual dimorphism, and adults focus on feeding and reproduction, featuring hardened exoskeletons for protection.
