Late small sulfur butterfly in my yard November 14-confirmed as Dainty sulfur species
I was quite surprised day before yesterday to spot a small yellow butterfly in my yard--though we have had pretty warm temperatures in Canon City this fall, the temps have fallen well below freezing on a number of occasions which has stopped flowering of most plants so not much for butterfly to nectar on. It was quite small, with a wingspan of about an inch.
I think it is a Dainty Sulfur (Nathalis iole) described here in BugGuide where I will submit it for expert identification. Also described in ButterfliesAndMoths.org which notes a documented sighting in my county (Fremont) of Colorado, albeit only one and several decades ago. SeEtta
Follow-up 11-17-13-BugGuide.org confirmed this as a Dainty sulfur butterfly.
