This is Mauna Kea, a dormant volcano and Hawaii's tallest mountain. Incredibly for a tropical island, its peak is covered with snow. Little can survive at such freezing heights. Bugs blown up here don't stand a chance. Stunned or trapped in snow, they slowly die. But not everything succumbs to the cold. These tiny creatures are wekiu bugs. Their cells are filled with a special kind of antifreeze that allows them to live around the snow line. Originally, wekiu bugs were seed-eating vegetarians, but their descendants have adapted to this hostile environment. Now with a taste for blood, they are the Pacific's own vampire bugs. Needle-sharp mouthparts pierce their dead and dying victims before they suck out anything that's left inside.
