Fun Facts about the Blue Death-Feigning Beetle

     The blue death-feigning beetle gets its bluish tint from a wax that it secretes to protect itself against overheating and dehydration.

     This beetle gets its name from its defense mechanism, playing dead! When they feel threatened they roll over onto their back and play dead. Their main predator, spiders, prefer live prey instead of dead husks.

     In 2018 the Cincinnati Zoo was the first zoo to successfully breed the blue death-feigning beetle
