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.
Green Grooved Dung Beetle
A metallic green and copper tunneling dung beetle with a prominent male horn that is slightly offset to one side. The pronotum is smoothly convex and brilliantly iridescent. Found in southeastern North American forests.
Did You Know?
The asymmetrical horn of the male is unique among North American Phanaeus species.
