Nationwide counts of Monarch butterflies are way down, but Monarchs, a rare Karner Blue, Swallowtails, and other butterflies are appearing in the sustainable landscaping of the U.S. Courthouse in Hammond, Indiana.

Now fully established, the sustainable landscaping of the Hammond Courthouse, opened in 2002, is one success story (see photo gallery of sustainable landscapes across the Great Lakes Region).

"The more food sources they find will help this species recover," said Rich Falzone, Courthouse Property Manager and a Master Gardener. "Over the last couple of years, GSA here in Hammond has been trying to maintain a self-sustaining natural habitat with suitable butterfly host plants."

"Wild lupine is native to the area and the only plant the Karner Blue female will lay her eggs on and the caterpillars can survive on," Falzone said. "We've had only limited success here in Hammond with growing these Lupine plants but will continue our efforts this summer."

National Pollinator Week, June 15-21, has been designated by the U.S. Senate, Dept. of Agriculture, and Interior.
