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.
