Samoan Rhinoceros Beetle
A large rhinoceros beetle found in Papua New Guinea, the Solomon Islands, and parts of Samoa. Males have a large forked horn on the head. It is associated with palm trees and is attracted to fermenting coconut sap.
Did You Know?
Males use their forked head horn to pry rival males off tree trunks during battles over feeding and mating sites.
Bornean Peacock Beetle
A small, dome-shaped leaf beetle with spectacular iridescent elytra that shift from purple to green to gold. The body is hemispherical and compact, resembling a tiny metallic droplet.
Did You Know?
The extreme iridescence is thought to confuse predators by creating shifting reflections that make the beetle hard to focus on.
