Life Cycle of Pigweed flea beetle
Egg The eggs of pigweed flea beetle are usually laid in clusters. During this phase, they are tiny and oval, often not easily visible to the naked eye. The characteristics at this stage include a lack of movement and a focus on incubation.
Larva Larvae of pigweed flea beetle hatch from eggs, appearing worm-like. They exhibit significant growth and molting. Their primary color is often different from the adults, and they lack wings. Feeding is the main activity at this stage, as they prepare for pupation.
Pupal In the pupal stage, pigweed flea beetle undergoes transformation inside a cocoon or a chrysalis. It is immobile and vulnerable during this time. Color changes and adult structures begin to form as the insect prepares for its final molt into adulthood.
Adult Emerging from the pupa, the adult pigweed flea beetle's development is marked by hardened exoskeleton, distinctive coloration, and the presence of wings. The body is fully formed, and the adult is mobile, focusing on reproduction and survival.

As larvae, pigweed flea beetle are typically found on or near their food plants, where they feed and grow, usually in similar wetland areas. When searching for larvae, check the leaves and stems of potential host plants. Pupae of pigweed flea beetle are generally located in the soil or concealed near the base of plants, and searching for them involves carefully examining the ground and leaf litter in the vicinity of host plants. Adult pigweed flea beetle are commonly observed on or near the same host plants or wandering in search of mates and new feeding sites. To find adults, inspect the foliage, flowers, and surrounding vegetation of plants in or near moisture-rich environments.

Agricultural Pests

Larvae of pigweed flea beetle feed on the leaves of host plants, leading to defoliation. Minor infestations may cause little noticeable damage, but severe outbreaks can result in extensive leaf loss, weakened plants, and reduced yields. This can indirectly impact humans through decreased agricultural productivity and economic loss.
