BEETLES OF EASTERN NORTH AMERICA: EASTERN RARE CLICK BEETLE
By Arthur V. Evans
The upper body surface of the eastern rare click beetle, Cerophytum pulsator (Haldeman), is dark reddish black to black, while the appendages and underside are usually lighter. The body is finely clothed with erect, yellowish setae. The elytra are somewhat dull, deeply grooved and finely, densely punctured.
Eastern rare click beetles are known from Pennsylvania to Florida, west to Illinois and Alabama. They prefer to live in mature, mostly deciduous forests. Adults are mostly active at night in spring and are collected at black light, in Malaise and Lindgren funnel traps, sweeping understory foliage, with rotten wood and bark, or in leaf litter. When held, they can “click” and are capable of jumping as a form of escape behavior.
