Forked Fungus Beetle Videos!

Below are a series of videos taken in the field near Mountain Lake Biological Station. Many of these videos were filmed by David Montgomery, an REU student of mine from Grinell College.

Video 1: A small horned male is courting a female (middle right). A much larger male tries to use his clypeal horns to pry the smaller male from the female's back. The video is at 10x speed.YouTube Link


Video 2: During combat a male uses his two sets of horns to pick another male off the fungus and throw him into beetle outer space (the leaf litter). The video is at 1x speed. YouTube Link


Video 3: One male sits alone, feeding off of the fungus. The invading male attacks him and they grapple.
