For example, the <a href="/wiki/Monarch_butterfly" title="Monarch butterfly">Monarch butterfly</a> often lays its eggs on certain toxic <a href="/wiki/Asclepias" title="Asclepias">milkweed</a> species when infected with parasites. These toxins reduce parasite growth in the offspring of the infected Monarch.
