Monarch

By grrlscientist on December 3, 2006.

Male monarch butterfly, Danaus plexippus,
on its host plant, Asclepias curassavica.
Notice the pheromone glands in the two dark spots,
one on each hindwing near the abdomen.
This Monarch was in very good condition so it is difficult
to know whether it was migrating since there is a small,
nearly-year-round population near Houston, Texas,
where this photo was taken.

You seem to have confused the butterfly with the foodplant. Or perhaps the sentence has a typo and was meant to say: "Male monarch butterfly on Asclepias curassavica." The scientific name you give is for a type of milkweed; the butterfly is Danaus plexippus. See http://en.wikipedia.org/wiki/Monarch_butterfly for more.
