The brown marmorated stink bug biology is similar to many of our native stink bugs and shares many traits with leaffooted bugs and smaller ‘true bugs’. Stink bugs have a general reproductive cycle that follows through the egg stage, the nymphal instars and eventually the adult stage. After hatching, first instar nymphs may aggregate around the egg clutch before molting and dispersing to feed. The southern green stink bug,Nezaraviridula(L.)(Hemiptera:Pentatomidae), is a cosmopolitan pest of fruit and row crops (Todd 1989).Intemperatecotton(Gossypiumhirsutum L.),-producing regions, the insects survive the winter as adults.

Stink bugs develop via incomplete metamorphosis, a process that involves three stages – eggs, nymphs and adults. Observation of mating behavior and multiple copulation.” Applied Entomology and Zoology 18: 234-242, via Tracy Leskey et al, 2011, “Biology, ecology, and management of brown marmorated stink bug in orchard crops, small fruit, grapes, vegetables, and ornamentals: USDA-NIFA SCRI coordinated agricultural project.” USDA-ARS Appalachian Fruit Research Station. Advanced. Life Cycle: Simple metamorphosis; adults deposit barrel-shaped eggs; immature stages develop through five stages or instars that appear similar to adults except that they do not have fully developed wings. … The brown marmorated stink bug, like all stink bugs, is a hemimetabolous insect. This is what science refers to as a true bug.

The green stink bug, Chinavia halaris(Say), is a commonly encountered pest of seeds, grain, nuts and fruit in both the nymph and adult stages across North America. BMSB may be able to produce several broods in a single year, thus increasing the potential and duration of risk for crop damage. Photo by W. Hershberger. Learn to identify BMSB across its life stages and recognize associated crop damage. [6] K. Kiritani, 2006, “Predicting impacts of global warming on population dynamics and distribution of arthropods in Japan.” Population Ecology 48: 5-12 via Leskey et al. BMSB commonly mates multiple times, and the female may deposit as many as 486 eggs in a lifetime. Juss. [3] A.L. It hatches into a nymph and then develops into an adult (three life stages—egg, nymph, adult). A second generation may occur in July and August. The stink bug life cycle consists of three stages – egg, nymph and adult. As they progress through their nymphal stages, they increase in size and eventually change into fully-grown winged adults capable of reproduction. Its inflorescence stems are racemes, and each one may have different stages of floral Early-stage nymphs do not venture very far from the newly hatched egg mass. Life Stages.
