These bugs are often found in large groups, particularly during the summer months when their food sources are abundant. According to a study published in the Journal of Agricultural Entomology, the Red Shouldered Bug is a significant pest of agricultural crops, particularly Zea plants.
Mating and Reproduction
The Red Shouldered Bug mates in the spring, with females laying their eggs on the underside of leaves. The eggs hatch into nymphs, which go through a series of molts before reaching adulthood. The entire life cycle of the bug, from egg to adult, takes approximately 30 to 40 days to complete. During this time, the bug goes through five stages of development, including egg, nymph, and adult.
Defense Mechanisms
The Red Shouldered Bug has a number of defense mechanisms that it uses to protect itself from predators. One of the most distinctive of these is its ability to release a foul-smelling liquid from its abdomen when threatened. This liquid, which is produced by glands in the bug’s abdomen, serves as a deterrent to predators and helps to protect the bug from harm. In addition to this defense mechanism, the Red Shouldered Bug is also able to fly quickly and erratically when threatened, making it difficult for predators to catch.
