The Eastern and Western Tailed Blues are quite similar in appearance, the major difference being the markings on their undersides. As their name implies, the ranges of these two butterflies also differ. The habitat of the Eastern Blue is east of the Rocky Mountains, while that of the Western Blue is west of the Rockies. Although sometimes they may cross over their usual habitat areas as they meet at the Rockies, they don t stray too far one way or the other. Blues are very small butterflies.
Blues like to feed on asters, wild flowering mustard, and also lupine.
They can also often be seen hovering very close to your lawn seeking nectar, especially if it happens to have small white clover blooming in it. So watch for these little fellows among some of their favorite flowers you may have in your garden. Some others in this family are the American Painted Lady, Painted Lady, West Coast Lady, and the strikingly beautiful Red Admiral. Buckeyes are quite easy to please when it comes to flowers. However, you will want to be sure to have a puddle nearby where the males can gather to bask.
