The 26 letters on the wings of a butterfly were photographed over a period of 24 years

According to foreign media reports, an American photographer has spent 24 years photographing all the "26 English letters" displayed by the butterfly wing pattern. All of these beautiful photos come from the bright patterns on the wings of moths and butterflies, each of which is unique and serves either to attract mates or as camouflage to avoid predators. niaolei.org.cn
