2025 April 18 evening
Jeremy Tatum saw his first non-Cabbage butterflies of the year today – three Western Spring Azures along Munn Road.
Aziza Cooper photographed a California Tortoiseshell on Mount Tolmie today. The three California Tortoiseshells reported this year on Mount Tolmie (see this posting, this morning’s posting of one seen yesterday, and the Apr 14 posting of one photographed by Marie on April 3) are three different individuals.
Jeremy Tatum also saw today’s California Tortoiseshell on Mount Tolmie. When he arrived, it was settled on one of the white spots on the reservoir’s surface. After a while, it flew up, and settled again on another of the white spots. I have often thought that these hill-topping nymphalids on the Mount Tolmie reservoir prefer to settle on the white spots.
Here is Aziza’s photograph of today’s butterfly:
