Black Swallowtail
Papilio polyxenes

Observation date: July 08, 2018
Submitted by: A_baldini
Specimen type: Sighting
Observation notes: Time: ~4:00 p.m. Weather: Very hot, fairly calm, and partly cloudy. Habitat: In a residential area; small, dry ditch consisting of mostly grasses and "weedy" plants (dandelions, hoary cress, lamb's ears, thistles, mallow, morning glories, etc.). Notes: A large Black Swallowtail resided behind my house (mostly in the ditch area) for a couple days (July 8-9). During that time, I sighted it on four different occasions. On the second occasion (July 8), I ran alongside it for long enough to confirm identification as Papilio polyxenes.
