Siam Crown Moth
A large silk moth closely related to the Atlas moth with warm cinnamon-brown wings and distinctive angular wing tips. The wing pattern features complex marbling and translucent triangular windows.
Did You Know?
The translucent wing windows are thought to help confuse predators by allowing the background to show through, breaking up the moth's silhouette.
Subarctic Dart Moth
A medium-sized moth with dark grayish-brown forewings marked with kidney and orbicular spots. It flies in midsummer across subarctic tundra. Larvae are typical cutworms that feed on low-growing tundra vegetation.
Did You Know?
The larvae spend the harsh Arctic winter frozen in the soil, resuming feeding for only a few weeks each summer.
