This yellow beetle was found in an outside water dish following a rain storm last night. It was in water with leaf debris. I thought it was dead, but it began moving once inside the house. What you cannot see from this image is the head is articulated and glows almost phosphorescent in direct light. The beetle is alive and appears to chomp on leaves in its container. If someone could please tell me what type beetle and what it generally eats, I would appreciate it. Thanks!
