Oil Beetle

A large, flightless beetle with shortened elytra and a swollen abdomen. It secretes an oily, blistering compound called cantharidin when threatened.

💡

Did You Know?

Females can lay over 1,000 eggs, but larvae must hitch a ride on a solitary bee to survive.

Tundra Leaf Beetle

A rounded, metallic reddish-brown leaf beetle with variable dark markings. Adults and larvae feed on willows in subarctic and mountain regions. Both stages produce chemical defenses derived from salicylates in willow leaves.

💡

Did You Know?

Larvae secrete droplets of salicylaldehyde derived from willow on their backs, creating a chemical shield that repels predators.
