Western Pygmy Blue on Sea Purslane — Brephidium exilis

The tiny Western Pygmy Blue (Brephidium exilis), one of the smallest butterflies in the world, rests on the succulent leaves of sea purslane (Sesuvium portulacastrum). These hardy coastal plants are crucial to shoreline ecosystems, and this butterfly’s subtle iridescence is a striking contrast against the thick green foliage. Photographed in a native coastal habitat.
