Xerociris wilsonii

Metamorphic stages of Wilson's Wood-nymph Moth. Why such a small moth from such a large larva? The answer lies in the cocoon building. 50% or more of body mass is lost in the process of gluing scraped wood into pulp for a more predator proofed casing.

Spring emergence is sporadic - first noticed in mid-April, fresh individuals have appeared throughout May. By June, it's hard to tell whether you're looking at a 1st brood from a late emerger or a 2nd brood from an early emerger. This "shotgun" approach to emergence is advantageous to the moth - it's likely one brood will hit rain and good times. Regardless, the drought hardy, semi-succulent, and tuberous rooted Sorrelvine (Cissus trifoliata [incisa]) makes a good host; it will be around in some condition, rainfall or not.
