Ptinus raptor
Ptinus raptorEastern spider beetles earned their name from their globular, rounded abdomens, long spindly legs, and tucked heads, which give them a striking arachnid-like silhouette. These nocturnal scavengers inhabit bird nests, rodent burrows, and dry human pantries, feeding quietly on forgotten organic debris, dried animal matter, and grains. Adults frequently feign death when disturbed, drawing their antennae and appendages tight against their bodies until danger passes.
