The alfalfa plant bug (Adelphocoris lineolatus) is a pest that is named from the plant that has become its primary victim, but it can feast on other plants as well. To make matters worse, it has become resistant to chemicals in some insecticides. There has been some success in using pheromones to disrupt their mating schedule.

Adelphocoris quadripunctatus is a fascinating insect known for its piercing-sucking mouthparts, which it expertly uses to feed on plant juices. With a life cycle that includes egg, nymph, and adult stages, it exhibits varying physical characteristics and dietary preferences throughout its development. In its nymph stage, it bears a resemblance to the adult but lacks fully developed wings. As a true bug, it navigates its habitat with an innate ability to blend into the foliage, making it an elusive sight for keen observers in its natural environment.

Red mountain laurel mirid exhibits a distinctive life cycle, progressing from eggs through a series of nymphal instars before reaching maturity. As a true hemimetabolous insect, it undergoes incomplete metamorphosis, meaning juveniles resemble adults but lack fully developed wings and reproductive structures until their final molt. This species follows a phytophagous diet, primarily feeding on plant juices obtained via specialized piercing-sucking mouthparts, playing a role in the complex web of herbivory within its ecosystem.
