Arctic Sawfly
A small, dark sawfly associated with willows in Arctic and subarctic regions. Females use their saw-like ovipositor to cut slits in willow leaves and stems for egg-laying. Larvae resemble caterpillars and feed openly on leaves.
Did You Know?
Arctic sawfly larvae can produce silk pads to anchor themselves to willow leaves during strong tundra winds.
Spiny Ant
A distinctive Asian ant with paired spines on the petiole and propodeum. Workers are metallic dark brown and build nests from silk produced by larvae, similar to weaver ants. Colonies are arboreal and highly territorial.
Did You Know?
They are commonly eaten as a protein-rich food in parts of southern China, where they are harvested from silk nests in trees.
