Before reaching their iconic beetle form, their larvae look like tiny, spiny, black-and-orange alligators\u2014highly aggressive little monsters that devour hundreds of pests before pupating. While they were intentionally introduced globally as an eco-friendly bio-control weapon, they\u2019ve since gone rogue. Today, they heavily outcompete native ladybird species and famously invade homes in massive swarms during the fall. To make matters worse, they possess a nasty defense mechanism: when stressed, they bleed a foul-smelling yellow fluid from their joints that easily stains walls and fabrics. While they are a blessing to farmers, they are a flat-out curse for winemakers. If these beetles are accidentally harvested and crushed along with the grapes, their stinky chemical secretions can completely ruin the flavor profile of an entire batch of wine! I crossed paths with this beautiful but controversial beetle in the garden of my family summer house in Serock, Poland.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Meet the multicolored Asian
