Yucca Giant-Skipper

One of North America's largest skippers with dark wings spotted in yellow-orange. Its massive caterpillar bores into yucca roots and stems, creating a silk-lined tunnel.

Did You Know?

The pupa wriggles up through the tunnel before emergence, and empty pupal skins protruding from yucca plants reveal their presence.

Mercury Islands Tusked Weta

One of New Zealands rarest insects, found only on Middle Mercury Island. Males have curved tusks on their mandibles used in territorial combat with rivals.
