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.
Arctic Psyllid
A tiny, winged sap-sucking insect that feeds on willow in Arctic and subarctic regions. Adults are brownish with transparent wings and can jump powerfully using enlarged hind legs. Nymphs produce waxy secretions.
Did You Know?
Psyllids are sometimes called jumping plant lice because they can leap more than 50 times their own body length to escape danger.
