Black Carpet Beetle (Attagenus megatoma). The black carpet beetle, a dermestid beetle, includes several similar species that may all be referred to as black carpet beetles. They usually have an annual life cycle. The adults feed only on flower nectar, pollen, and free water, while the larvae usually feed on wool, leather, silk, fur, and other animal products. Several species of these insects are found worldwide, but more commonly in temperate areas. The adult females produce a sex pheromone useful in detecting and monitoring the insect (Figure 19).
