Monarch Butterfly, Danaus plexippus
The monarchs are among the best known of the world’s butterflies due to their remarkable ability to migrate, wide distribution, and charismatic appearance. Orange-and-black warning coloration of monarchs is noticeable, and its memorable pattern is directed at repelling insectivorous birds. Experiments conducted with captive blue jays showed that monarchs indeed are toxic (Brower et al. 1968)
