As it climbs and searches for females, it also seeks out other males in the vicinity. When two males meet, they fight. Males use their jaws in combat: they hook them under the opposite beetle's wings, pull up and throw their opponent to the ground (from 20 meters above, as they are in great trees most of the time). Charles Darwin collected the species in Chile during the Second voyage of HMS Beagle, second voyage of HMS Beagle, HMS ''Beagle'', and, despite the enlarged Mandible (arthropod), mandibles of the males, he noted that the jaws were "not so strong as to produce pain to finger".
