Coleoptera

  • A metallic green tiger beetle at the bottom of an orange plastic jar.
    Tiger beetles are some of the most charismatic insects on Earth: metallic, sharp-eyed, absurdly fast, and every bit as predatory as their name suggests. Come learn how they hunt, why their larvae live like tiny trapdoor monsters in the soil, and what their decline says about the fragile open habitats many other species need too.
