Orange Sulphur (Colias eurytheme). A butterfly that flitters about with a wingspan of 1.5 to 2.5 inches. It has a large range, found from southern Canada to central Mexico. Being a generalist, its host plant is often vetch, clover, alfalfa, and other pea family plants. Eggs are laid on the host plant and hatch 4 to 5 days later.

The lifespan of the adult Orange Sulphur is 2 to 4 weeks and during their short life they consume the nectar of alfalfa, clover, milkweeds, plants in the sunflower (aster) family and many others.

Difficult to capture, the dorsal side of the wings. In this photo I’ve recorded the information, a rich yellow-orange. Not just a yellow butterfly, but an Orange Sulphur Butterfly.

*August 10, 2022. Last night, after putting together another blog post on these yellow/orange butterflies, I’ve realized that the butterfly in the above image is actually a Sleepy Orange (Eurema nicippe). This had been identified as an Orange Sulphur Butterfly in my post titled:  Orange Sulphur Butterflies. The telltale marking, the thin black line at the top of the forward dorsal wing is what convinces me.
