we had caterpillars, and gave them a choice:medicinal milkweed versus non-medicinal milkweed.And then we measured how much they ate of each species over their lifetime.
It's another coevolutionary relationship, and here's the story.Milkweed is toxic.It has a poison in it that it evolved to deter other insects from eating it,
but the monarch developed a different kind of relationship,a different strategy with the milkweed.Not only does it tolerate the toxin,
and the reason for this is that monarchs are extremely picky eaters.They only eat milkweed as larvae.Luckily, there are several species of milkweed that they can use,
Monarch butterflies will only lay their eggs on milkweed,and monarch caterpillars will only eat milkweed,because they need that toxin to actually create what they are as a species.
