Key Visual Features
The varied carpet beetle (Anthrenus verbasci) is a small beetle recognized by its intricate scale pattern.
- Size: adults are quite small, about 1/16 to 1/8 inch long.
- Color: covered in tiny colored scales arranged in a mottled pattern of white, brown, yellow, and black, giving a speckled, variegated look rather than a solid color.
- Body shape: oval and domed, compact and rounded, similar in general outline to a small ladybird beetle but with a duller, patterned surface.
- Antennae: short, clubbed antennae that fold back against the body and are not easily visible without close inspection.
- Larvae: distinctly different from adults — elongated, tapering, and covered in dense tufts of bristly hair in shades of brown and tan, often called "woolly bears" on a small scale, with longer hair tufts near the rear end.
Where and When You'd See It
- Adults are often found near windows, on flowers outdoors (where they feed on pollen and nectar), or indoors where they may wander after emerging.
- Larvae are the more commonly noticed indoor stage, found in dark, undisturbed areas such as closets, under furniture, in air ducts, and around stored fabric items.
- Most active in spring and early summer when adults emerge and disperse to find mates and lay eggs.
- Shed larval skins, which retain the bristly appearance, are often found in infested areas even after larvae move on.
Similar-Looking Bugs
- Black carpet beetle: solid dark brown to black without the mottled scale pattern, and its larvae are smoother and more uniformly colored without dense bristle tufts.
- Ladybird beetles: more rounded and glossy with solid or spotted coloring, lacking the fine mottled scale texture of the carpet beetle.
- Furniture carpet beetle: similar mottled pattern but with subtle differences in scale color arrangement, best distinguished under magnification.
Quick ID Checklist
- Tiny, oval, domed body under 1/8 inch
- Mottled pattern of white, brown, yellow, and black scales
- Short clubbed antennae folded against the body
- Larvae are bristly, tapering, and brown-tan colored
- Adults often found near windows or on flowers
