Even as late as mid-September, monarch butterflies are depositing eggs on milkweed in Eastern Iowa.
If Iowa’s weather cooperates, those eggs will hatch in about four days to become tiny larvae, or caterpillars, which feast on the milkweed for two weeks before transforming into a chrysalis.

For advocates who raise monarchs indoors, the sight is a common one, but each is its own little miracle.
After seeing dozens of caterpillars this summer, this one attached onto a window ledge and emerged after about 10 days.
It spent several hours letting its wings dry before joining the generation of monarchs to make the long trek to winter resting grounds in Mexico.
