First find the total number of snakes eaten: 5 snakes/jaguar * 6 jaguars = <<5*6=30>>30 snakes
Then find the total number of birds eaten per day: 30 snakes * 3 birds/snake = <<30*3=90>>90 snakes
Then multiply the number of snakes by the number of beetles per snake to find the total number of beetles eaten per day: 90 snakes * 12 beetles/snake = <<90*12=1080>>1080 beetles
