Black Swallowtail
Papilio polyxenes

Observation date: August 02, 2015
Submitted by: kpflaumer
Specimen type: Photograph
Observation notes: Not active, sitting on a fennel plant in my urban garden plot in West Philadelphia. There is always fennel in the plot and I saw one of these last year on a fennel as well. I am assuming black swallowtail because of range but it does look a lot like the pictures of anise swallowtail caterpillars the Internet is turning up (assuming those are correctly identified). Nearby plants include beans, onions, carrots, lamb's quarters, and sow thistle, but pretty sure fennel is the host.
