Monarch Butterfly on Tithonia rotundifolia

Here is a monarch butterfly (Danaus plexippus) on Mexican Sunflower (Tithonia rotundifolia var. 'Torch').  The Tithonia rotundifolia at Horticulture Gardens is especially attractive to butterflies.  On this day I noticed about a half dozen monarch butterflies feeding on the Tithonia flowers here.  Photo taken September 2, 2015.
