Walkers find rare animal – “You can compare it with 6 correct ones in the lottery”. Black-blue oil beetle discovered: “I didn’t realize they were so rare” It seems to be a rare animal that one should even “bow down” to.
But be careful: oil beetles are poisonous. They contain the defensive secretion cantharidin. This can cause severe irritation to the skin and mucous membranes in humans. However, eating or swallowing a single black-and- blue oil beetle is not fatal.
