Habitat Preferences of Scentless plant bug Through Different Life Stages
The eggs of scentless plant bug are typically laid on the undersides of host plant leaves. Nymphs, sharing a similar habitat, can be found clustered around the stems or at the base of the plants, where they feed and undergo several instars. Adults prefer the same vegetative areas but might also be spotted on flowers or neighboring plants, as they have wings and are more mobile. To find these stages, inspect the host plants in the native regions, carefully turning leaves to locate the eggs, observing the stems and leaf axils for nymphs, and scanning vegetation for adults. The environment is key, and a suitable habitat such as grasslands or cultivated fields where host plants are abundant would be ideal for a search.
