Chalcosoma atlas beetle spread winged. Watercolor postcard.
I love painting these guys. They get pretty big at lengths of up to 25-60 millimeters in length. Their larva is known for fierce behavior. It’ll bite ya if touched. Unverified reports exist of Chalcosoma larvae that live together, fighting to the death if space or food are insufficient.
Watercolor on Canson toned paper.
