Last look: One of the teen volunteers who helped run the Butterfly Station at Farnsworth Middle School this summer prepares to release a monarch for its flight to Mexico. The iconic species has seen its numbers decrease by 90 percent from the eastern coast of the United States to overwinter in Mexico. Scientists believe the decline is caused by herbicide use and loss of habitat, including less milkweed upon which the butterfly depends.
