The antennae of eastern false click beetles, Cerophytum pulsator (Haldeman) (5.4-8.5 mm), are comb-like (males) or saw-toothed (females).

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.

  1. I wonder why they call these “rare click beetles”, as I’ve seen them rather commonly at blacklights in mature white oak forest.

    • Arthur Evans Says:

      Beats the heck out of me! They must have been “rare” at one time or another within their current range. They were newly recorded in VA just a few years ago and I have only seen a handful, usually dead in a Malaise trap. The photo is of the first individual that I have ever seen alive and was taken in a black light trap.

  2. Hey. This article is very useful for me to have a good knowledge of eyed click beetle. I’m collecting the pictures of every phase of this insect, but sadly, I can’t find any clear pictures of its eggs. If you have some, can you please sent the pictures of its first phase (egg) to my email: ? I’ll be very appreciated. Thanks for advance.
