The loud, high-pitched chirping or whistling noise you hear throughout the night in Antigua (and much of the Caribbean) is primarily caused by the Johnstone’s Whistling Frog (Eleutherodactylus johnstonei). Despite their incredibly loud "boop-beeeep" call, these frogs are remarkably tiny, often smaller than a thumbnail, making them nearly impossible to spot in the foliage. The males produce this sound to attract mates and defend their territory, with the chorus becoming particularly deafening after a tropical rainstorm. Another contributor to the nighttime soundscape is the Snowy Tree Cricket, which produces a constant, rhythmic buzzing or "sawing" drone by rubbing its wings together. In rural areas, you may also hear the "Money Bug" (a type of cicada) which creates a harsh, metallic trill. While the noise can be startlingly loud for first-time visitors, it is a hallmark of the Caribbean environment and a sign of a healthy, biodiverse ecosystem. Most hotels provide earplugs for light sleepers, though many locals and repeat visitors find the natural "lullaby" of the whistling frogs to be a soothing and essential part of the island experience.
