African black beetle

African black beetle

Heteronychus arator

A species of Heteronychus

The african black beetle (Heteronychus arator), also commonly known as the "black maize beetle", is a pest to pastures, turf, and agricultural crops. It spends the majority of its life underground, so it causes the most damage to crop stems below the surface, including corn, grapes, and potatoes. This species is nocturnal, so it only comes to the surface at night.

Life Cycle of African black beetle
Egg The egg phase marks the beginning of african black beetle's life cycle. The eggs are usually oval and laid in safe locations. Color and size depend on the species, but they tend to be small and inconspicuous to avoid predation.
Larva The larval stage of african black beetle showcases drastic growth in size. Larvae appear worm-like with a distinct head and chewing mouthparts for feeding voraciously, often on plant roots. Larvae undergo several molts, becoming larger with each stage.
Pupal Transitioning into the pupal stage, african black beetle becomes encased in a protective shell. During this time, it undergoes significant transformation. The pupa is immobile, and changes in internal structure and external morphology prepare for adult life.
Adult Emerging from the pupa, the adult african black beetle’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction and may display varied colors.
