So I was watching animal planet yesterday and there was a about monarch butterflies. The caterpillars only eat milkweed. The weed contains alkaloids which are stored in caterpillar and make predators ill if they eat caterpillar. Now the word alkaloids really got my attention, so I looked around and all I could find was a one line reference to pyschedelic caterpillars on erowid. The questions I have is does anybody know what alkaloids are in milkweed? Or has anybody ever actually eaten a monarch caterpillar? Im still researching this but I firgured maybe someone here could save me some time.
