Monarch Butterfly (Danaus plexippus) and related species are found on all continents except the polar regions, wherever milkweed and related plants are found. The milkweed provides the Monarch with an intriguing form of protection, since the milkweed juices assimilated by the Monarch make it poisonous to predatory birds. The beautiful orange color of the Monarch butterfly serves to teach predators that their intended meal might be toxic. Not all milkweeds produce cardiac glycosides, therefore not all Monarchs are poisonous. However, the warning orange color serves to disguise poisonous from the non-toxic Monarch.

The magnet measures 2.5” x 3.5” (6.35 x 8.89cm) with a metal shell, mylar/UV protecting cover and flat magnetic back. The artwork is a reproduction of an original line art drawing by wildlife illustrator Roger Hall.
