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.
Blue Margined Ground Beetle
A brilliantly colored ground beetle with bright metallic blue-green elytra and a velvety texture from fine pubescence. It is found near wetland habitats across North America.
Did You Know?
Its defensive secretions have been analyzed and found to contain complex chemicals that not only repel predators but also have antimicrobial properties.
