About Parallelostethus attenuatus (Say, 1825)
Parallelostethus attenuatus is a click beetle species that belongs to the family Elateridae. Adult male P. attenuatus beetles are strongly attracted by 1,8-Octanediol di-hexanoate, and this compound may be the only component of the species' sex attractant pheromone. The hinge structures that P. attenuatus uses to perform its clicking movement have been studied in close detail. In Indiana, this species is commonly found in rotten logs, where it feeds on decaying moist wood tissue. Elateridae as a group are commonly found in wood across Indiana.
