One-and-half-hour, late-afternoon walk on the warmest day of the year. (Mid-70s)
My first Spring Azures of the year, and first Falcate Orangetip of the year.
But surprised not to see a single anglewing or Mourning Cloak, despite checking out the areas where I’ve observed them in the past in the spring.
Meanwhile, only this weekend, Cabbage Whites were becoming common alongside roads in southeastern Pennsylvania & neighboring Delaware and Maryland.
