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.

Mottled Umber Moth

A variably patterned brown moth where males range from pale to almost black. Females are completely wingless and resemble small spiders.

💡

Did You Know?

Wingless females attract mates by releasing pheromones from the trunk of their host tree.
