Loricera Bristly Ground Beetle

A small, distinctive ground beetle with uniquely modified antennae bearing long bristles. These bristle-fringed antennae act as a cage to trap springtails, its primary prey.

Its antennae are unique among beetles - long bristles form a basket-like trap that pins springtails against the ground before the beetle's mandibles can grab them.

Harvester Butterfly

The only carnivorous butterfly in North America, whose caterpillar feeds on woolly aphids rather than plants. Adults are small and orange-brown with dark spotting.

💡
