Palorus

Palorus is a genus of small to medium-sized beetles belonging to the family Tenebrionidae, commonly known as darkling beetles. These beetles are characterized by their elongated, somewhat flattened bodies and their antennae, which are typically filiform or slightly serrated. The coloration of Palorus species often ranges from light brown to dark brown or black.

The genus Palorus is found worldwide, with many species being cosmopolitan in their distribution due to their association with stored products. They are frequently encountered in grain elevators, warehouses, and homes where stored food items are present. Their larvae, like the adults, are small and active.

Palorus beetles are often considered pests because they can infest and damage stored grains, cereals, flour, and other dry food products. While they may not cause catastrophic losses, their presence can lead to spoilage and contamination. Some species are also found in association with fungi and decaying organic matter in natural environments, but their economic significance is primarily linked to stored product infestations. Identification of different Palorus species often relies on detailed examination of their morphological features.
