Kudzu beetles are a type of bug and are often referred to as true bugs because they possess semi-membranous wings and piercing-sucking mouthparts. Many people confuse them with conventional beetles, but they can be differentiated from them due to their beaklike sucking mouthparts, while conventional beetles have chewing mouthparts. They are also called as lablab bugs, globular stink bugs, or bean plataspidae. They were first found in Georgia, and then they were observed to move to the surrounding lands.

They lay their eggs on the underside of host plants, and they then convert into adults while going through the nymph stage in between.

Kudzu beetle Spray Lifecycle

The lifecycle of the Kudzu Beetle is called bivoltine, primarily in the USA. This means that they give birth to two generations in a year.

Their lifecycle consists of three stages, and they go through an incomplete metamorphosis after being hatched.


Female bugs lay their eggs onto Kudzu leaves, soybeans, and wisteria. These eggs hatch in a pattern of two rows with 15 eggs in each row. Underneath the eggs, there are capsules of endosymbiotic bacteria, which should be consumed by the bugs after hatching.


There are five more stages in the nymph stage for a Kudzu beetle. Nymphs have a hairy appearance, and they can vary in color. It took about 6 to 8 weeks for a nymph to convert itself into an adult.


During the season of late fall and upcoming winter months, the adult Kudzu beetles can overwinter in homes, leaf litter, attics, or under tree barks. They resume their feeding and reproduction when the winter season passes.

Besides, the beetle is not just harmful and restricted to homes or confined spaces but can also cause extensive damage to crops and fields. They cause million-dollar crop loss every year and are now becoming an issue for homes, offices, etc. as they also reside indoors.

Swarming is a phenomenon of splitting a single colony of beetles into two or more distinct colonies. It usually occurs during the spring season and is two to three weeks long, and sometimes it can happen throughout the spring season.
