California Tortoiseshell
Nymphalis californica

Observation date: March 26, 2026
Submitted by: sandyleapt
Specimen type: Photograph
Observation notes: Three butterflies in my garden. Chasing, doing upward spiral. One settled on Pieris japonica shrub and extended its proboscis to the flower stalk and sat sipping for a while. At least 2 butterflies still in the garden on March 28, 2026. I have been seeing butterflies that look like California Tortoiseshells in flight various places I go birdwatching for the last two weeks. Perhaps another big year for this butterfly?
