When viewed from above, most beetles appear to have three clear sections, but this is deceptive: on the beetle's upper surface, the middle section is a hard plate called the pronotum, which is only the front part of the thorax; the back part of the thorax is concealed by the beetle's wings. This further segmentation is usually best seen on the ...
This species is most abundant between October and December, then from January through mid-May. It is of modest size, ranging in length from 10–14 mm.

The color of their antennae are completely black. [2] Their orange and black markings serve as a warning sign to avian predators that defends them from attack.
The larva of the black larder beetle has less strongly curved appendages. Mature larvae of both species tend to bore into hard substrates such as wood, cork, and plaster to pupate. [4] Adult larder beetles are generally 1/3 to 3/8 of an inch long and are dark brown with a broad, pale yellow spotted band across the upper portion of the elytra ...
