Red-legged ham beetle

Red-legged ham beetle

Necrobia rufipes

A species of Necrobia, Also known as Red-legged copra beetle

Contrary to what the name may suggest, the red-legged ham beetle (Necrobia rufipes) does not have an affinity for ham. It bores into ham in order to chase after the larva of blowflies (Calliphora). To prevent this, most people simply refrigerate their ham. But they attack a variety of other foods. They are also considered an incredible pest for salt fish like herring.

Pupal During the pupal stage, red-legged ham beetle transform inside a protective cocoon. They are immobile and undergo significant changes in physiology and structure, including developing wings and compound eyes, preparing for adult life.
Adult Emerging from the pupa, the adult red-legged ham 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.

Stored Produce Pest

Red-legged ham beetle is a stored produce pest that can cause both mild and severe damage. At the larval and adult stages, it infests items like dried meats and cheeses. These insects can lead to spoilage and economic losses due to their feeding behavior. Control measures are necessary to mitigate their impact on stored goods.
