In the 1960s, the cinnabar moth became the main control agent for an exotic weed in Oregon called tansy ragwort. This commonly found weed is highly poisonous and can cause liver failure in deer or livestock that graze on it. The cinnabar moth was one of three natural enemies released in order to control the spread of the weed. The moths lay their eggs on the underside of the leaves, and soon, small caterpillars emerge and begin feeding on the ragwort. In the process of chowing down, the caterpillars absorb toxic alkaloid substances from the plants, making them taste terrible to potential predators. Talk about a win-win situation! #pollinatormonday
