Southern Dogface
Zerene cesonia

Observation date: April 17, 2026
Submitted by: zencoyote
Specimen type: Photograph
Observation notes: Sped past among the desert foliage. Weather clear, slightly breezy, mid 70’s. Very few flyers about, mostly Sulphurs. Update: I added a couple more frames from my video, and I don’t think this is Boisduval’s yellow. The “dog-face” markings are too clearly different from that species.
