YAY I am excited, I plan on watching my first butterfly emerge... even though I have raised over 50 gulf frittilary, they always emerge when im not there :angry:
My monarchs eclosed in the mornings between 8 and 9am but they were outdoors on my front porch. It seemed that they emerged very soon after the colors started showing through their transparent pupal casing.
Sorry, I don't remember exactly how long, but I would start checking every morning after the pupae turn dark.
