One of the best-known butterfly species, the beautiful monarch butterfly is renowned for its spectacular, long-distance annual migrations. The adult monarch butterfly is brightly coloured, with orange upperwings, interlaced with black veins and surrounded by a wide, black border marked with numerous white spots. While the striking colouration of the upperwings serves as a visual warning to predators that this species is poisonous, the undersurface of the wings is duller orange, and helps to camouflage this species against tree. Being so close to the beach the air is fresh and invigorating.
