This comma was a bit larger and much brighter/golder than the numerous Green Commas (P. faunus) fluttering about that day. Unfortunately, I did not get a ventral view, which would confirm the ID. The dorsal view fits Oreas Comma fairly well, particularly with the dark central hindwing spot, however several experts have chimed in that Zephyr Comma can show that spot on occasion as well and that this butterfly is mostly likely a 'Zephyr' (Hoary) Comma, especially considering the rarity of P. oreas.
