    Myriophora are initially attracted to the chemical toxin released by their host that is used to keep predators away. However, this same toxin is what attracts the Myriophora. Specifically, the flies are more attracted when 2-methoxy-3-methyl-1,4-benzoquinone is combined with another chemical 2-methyl-1,4-benzoquinone. [2]
