Blue Swallowtail Butterfly Women's Pocket Tee

The Pipevine Swallowtail (Battus philenor). Iridescent blue scales catch sun like stained glass. Caterpillars feed only on toxic pipevine — and wear their poison.

Pocket-printed from a hand-painted original — cropped from a full iPad painting observed from life — with a numbered field tag included.

Women's pocket tee for lepidopterists, field-notebook keepers, and anyone who has stopped for this animal in the wild.
