A critically endangered moth discovered in 2026, known only from a small grove of roughly 30 sandalwood trees on the island of Lanai. Its larvae mine sandalwood leaves.
Did You Know?
This moth is known from just one grove of 30 trees — if those sandalwood trees disappear, this entire species vanishes with them.
Birch Leaf-Roller Sawfly

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