Butterfly populations are a very good indicator of the health of an area's ecosystem !!
Also known as the Cosmopolitan or the Thistle Butterfly
The Painted Lady (Vanessa cardui) is almost globally distributed, only being exempt from South America and Antartica.
Painted Lady larvae feed on a wide variety of host plants especially thistles, hollyhock, common mallow and a number of legumes including Iowa soybeans.
Females are generally larger than males.
The number of broods in any one place in the U.S. may vary from year to year because it is not a permanent resident in most of the country.
