Euthysanius sp. – An arboreal click beetle

Adult: 20mm.

Order Coleoptera/ Family Elateridae/ Subfamily Oestodinae

Euthysanius is common to the Reserve as evidenced from those caught in pheremone traps in summer to fall months of 2001, but nothing seems to be known of their habits except that they are subcortical, being found under the bark of various Pinus spp.. Whether the larvae are predators of other bark insects or feed in rotting wood, is yet to be discovered. The pectinate, or branched antennae is diagnostic of this elaterid species, though they are also a feature of the closely related False Click Beetles, the Eucnemidae, which are also found to be subcortical in habit.
