Hello, I hope you’re both well.
I think this is a Sulphur Butterfly, possibly an Orange Sulphur.
You kindly identified one for me last year; I’m noticing that the same butterfly species that visited a year ago have returned to the same patch of wildflowers this winter.
Many of the honeybees and butterflies seem to have very worn wings at this time. I’m guessing that this might be from the unusually cold, icy, and very windy weather that has occurred this winter. So glad for spring-like weather this week!
We agree that this is an Orange Sulphur, Colias eurytheme, and we grew up calling it an Alfalfa Butterfly. BugGuide also indicates the common name Alfalfa Sulphur. The spotted border of the upper wings indicates that this is a female. The male has a solid black border.
