💡

Did You Know?

The atlas moth has no mouth — as an adult, it cannot eat. It survives entirely on fat stored during its caterpillar stage, living just long enough to mate.

Cranberry Blue

A small butterfly with violet-blue upperwings in males and dark brown in females. The hindwing underside has a diagnostic metallic silver spot. It frequents boggy habitats where its larval foodplant cranberry grows.
