Polyphemus Silkmoth Cocoon -- Antheraea polyphemus
***Overwintering pupae. Keep cool on a natural light cycle, and fridge per overwintering blog instructions at Thanksgiving.
****SHIPPING to ALL 50 States. USDA permits not required for this species.
This is the largest silkmoth in the pacific northwest. Caterpillars get huge, feeding on a variety to broadleaf trees.
Adult moths do not feed. Instead they live off their built up energy reserves from the larval stage. Because of this, the moths only live about 7-10 days after hatching in spring.
