Asters are blooming. Syrphid flies aka Flower Flies are visiting them. The USDA writes, “Flies are among the most frequent visitors to flowers and important pollinators of a wide range of plants. Syrphid flies are often referred to as flower flies….The Syrphidae family is broken down into 3 subfamilies and 15 tribes, containing more than 6,000 identified species.”

Fall migration has begun in the city. Don’t be fooled by the park’s 10 acres. Washington Square hosts migratory birds. Recent species seen are: Black-and-White Warbler, Northern Parula, Common Yellowthroat, Eastern Wood Pewee.

The major seasonal change happening in the tree world is the maturation of fruits and cones. Follow us on Instagram for all things WSP phenology.
