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.
