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.
Miyama Sawtooth Stag Beetle
An elegant stag beetle found in southern Japan with distinctive serrated mandibles. The species occurs in the subtropical forests of the Ryukyu Islands. Males show considerable size variation.
Did You Know?
The Ryukyu Islands have produced many unique stag beetle species due to their isolation, making them a hotspot for lucanid diversity.
