Pine-tree Lappet
A large moth that can be a devastating forest pest, with caterpillars capable of completely defoliating pine forests across Eurasia. Major outbreaks are cyclical and can last several years.
Did You Know?
During outbreak years, caterpillars can strip entire pine forests bare, causing economic losses of millions of dollars.
Birch Leaf-Roller Sawfly
A flat-bodied sawfly with long, thread-like antennae and a broad abdomen. Larvae roll birch leaves into tubes using silk and feed inside these shelters.

The larva creates an elaborate rolled-leaf shelter that protects it from both predators and weather while it feeds inside.
