How To Find Eastern Tailed-Blue Butterflies

  • Flight Season: End of March through October.
  • Look for adult Eastern Tailed-Blue Butterflies in open, sunny areas with low-growing vegetation, like meadows, fields, and overgrown lawns. They are also common in disturbed areas like power line cuts and along railroads.
  • Adult butterflies feed on nectar from a wide variety of flowering plants, especially:
    • White Sweet Clover (Melilotus alba)
    • Butterfly Weed (Asclepias tuberosa)
    • Daisy Fleabane (Erigeron annuus)
  • These butterflies like to fly low, almost hugging the ground, and have a fast, fluttery, up and down flight.
  • They can be hard to see when perched because of their small size and relatively inconspicuous ventral wing surface coloration.
    • The best way to spot these butterflies is to wait motionless in a likely habitat, like a flowery meadow, and watch carefully for flitting motion inches above the tops of the plants. Follow the butterfly with your eyes until it lands.
  • Male Eastern Tailed-Blue Butterflies also like to “puddle” or gather around damp soil to drink salts and other minerals.
