Here’s a beetle that the genetics-inclined entomologist will recognize. Tribolium castaneum, the red flour beetle, was the first Coleopteran to have its genome sequenced.
This small tenebrionid is native to the Indo-Australian region but has become a pest of stored grains around the world. I photographed these individuals from a lab culture at the University of Arizona where they were being used in studies on beetle development.
