Physical Characteristics

There’s nothing confused about this reddish-brown beetle, whose adults are capsule-shaped and 1/8 inch in length. It’s just that people confused it with some other beetles, like the red flour beetle. The confused flour beetle has antennae whose scape gently tapers outward to a four-segment club, however, and its sides are straighter than the more rounded red flour beetle, whose antennae have a marked difference between its narrow scape and thicker club segment. Adults have wings under their elytra, but they’ve never been observed in flight. Larvae are 1/8 to 1/4 in length and whitish-yellowish in color, with a darker two-pronged tail segment (similar to red flour beetle larvae).

Confused Flour Beetle


The confused flour beetle can’t feed on whole kernels, or undamaged grain. It will feed on grain and grain products, peas, beans, shelled nuts, dried fruit, spices, milk chocolate, drugs, snuff tobacco and cayenne pepper. When confused flour beetles infest flour, they often will leave it smelling and tasting foul, but non-toxic.
