The Baltimore Checkerspot is a popular butterfly that was named the Maryland state insect in 1973. The Baltimore was named for the first Lord Baltimore, whose coat of arms matched the colors on this butterfly. The Baltimore is black, with an orange rim of spots on its outer wing, and rows of white spots on the inner wing.
