One of several cabbage white butterflies seen today. It was not warm enough for a lot of butterfly activity, unfortunately. There were many other insects out, however. Lots of bumblebee queens, but also, for the first time this year, I saw workers, meaning that those early queen bees I saw have established a successful colony. There were also various syrphid flies, brilliant green halictid bees, some andrenid bees, and many haploa caterpillars.
