Observation notes: I had a rare form of eastern black swallowtail butterfly emerge from chrysalis in an enclosure in my home this morning. It was found in caterpillar form in my butterfly garden eating fennel. It was brought inside and went in to chrysalis on 6/7/19 and emerged this morning 6/20/19.

Coordinator notes: This is an uncommon yellow form of polyxenes, asterius fm-pseudoamericus, sometimes seen in west TX, NM, Mexico, or other areas related to, but distinct from, ssp. coloro which is resident further west in AZ, CA, NV. Here is a sighting on bugguide.net from NM that resembles this sighting with some discussion.
