Life Cycle of Orius niger
Egg The egg phase is the beginning, where the orius niger is stationary and encapsulated. Substrate selection for oviposition is crucial, as it impacts survival and development time.
Nymph Emerging from eggs, the nymphs resemble miniature adults but lack fully developed wings. Nymphs undergo several molts, increasing in size and maturity after each molt, with wing buds becoming more prominent.
Adult Completing growth, the adult orius niger possesses full-sized wings and functional reproductive organs. Their exoskeleton is hardened and pigmented, signaling sexual maturity and readiness for mating and oviposition.

As nymphs, they remain in similar vegetative habitats, often on flowers or leaves where they feed on prey like aphids. Adult orius niger are usually found in agricultural fields, gardens or wherever their prey is abundant. To search for these insects, one should carefully inspect the undersides of leaves, flowers, and stems during the appropriate season when the insects are known to be active.
