アメリカ自然史博物館さんのインスタグラム写真 - (アメリカ自然史博物館Instagram)「Summer is in full swing, which means firefly season is officially here! Did you know that there are more than 2,000 known species of fireflies worldwide? Most communicate with patterns of flashing light, illuminating the night with their bioluminescence. These signals are used to find and attract mates, deceive other firefly species, and avoid predators. Fireflies produce light by blending a cocktail of two chemicals—luciferin and luciferase—in a specialized organ known as their lantern.
