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.
