Van Cortlandt Park, woodlands only
Bronx County, NY
Spicebush Swallowtails were each males and appeared very freshly-emerged. The Summer Azure is the usual species of azure found in this park, the true “spring” forms are all rare, or very rare there. We have seen at least occasional “Summer” azures in N.Y. City in the spring months, including in other places where the ‘spring’ forms would be rare to very rare. Also, this is not an earliest date for Summer azure in N.Y. City. Today’s visit was very late, but with warmth & sun, a few nice observations.
