Named for the moon, this pastel green giant silk moth lives at most one week after emerging from its cocoon. While many moths are shades of brown and gray as visual camouflage, Luna moths fly only by night and exhibit acoustic camouflage. Their long, dangling hindwings have a twist near the end that flutters and confuses creatures with echolocation—namely the bats that prey on them. Because the echoes become muddled, the bats struggle to pinpoint the moth’s exact location.
