Egg The two-Spotted Carpet beetle begins life as an egg. The eggs are small and often laid in protected locations with ample food sources available upon hatching.
Larva After hatching, the larva of two-Spotted Carpet beetle emerges, consuming food voraciously to fuel rapid growth. During this period, larva will molt multiple times, increasing in size with each stage.
Pupal Once the larva of two-Spotted Carpet beetle reaches a certain size, it transforms into a pupa. In this immobile stage, the organism undergoes significant transformation, reorganizing internally to become an adult.
Adult Emerging from the pupa, the adult two-Spotted Carpet 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.

Buffalo carpet beetle
Buffalo carpet beetle

The adult common carpet beetle varies from about 2.5 - 4 mm in length. The antennae have eleven segments, three of which form a club, and the eyes are notched at the front. The head is black but is largely concealed under the prothorax, which is also black, liberally speckled with white scales apart from a band in the centre. The elytra (wing cases) are black with orange or reddish scales near the midline and variable but symmetric patches of white scales elsewhere. As the beetle gets older, the scales tend to get rubbed off so the beetle changes in appearance. The small white eggs are laid in batches of 30 to 60 and have projections which help them to adhere to carpet fibres. The larvae are brown and moult five times before pupating; the final instar larva is hairy and larger than the adult beetle. Pupation takes place in the last larval skin.
