Cloudless Sulphurs are big compared to other Sulphurs. They have a wingspan of about 2 1/2- 2 3/4 inches. This butterfly has a wide range, from South America to Southern Canada.
The Sulphurs’ major food plant is Cassia. Near the beginning of spring I saved up my money and was very excited to purchase one.
After waiting a month I finally spotted some eggs on my Cassia, but I missed getting to watch the Cloudless Sulphur lay the tiny eggs. Finally this summer I captured a photo of the Sulphur butterfly laying eggs!
Can you find the tiny white egg on this leaf? It looks like a grain of rice. It takes about six days for the caterpillar inside to fully develop.
All my Cloudless Sulphur caterpillars get eaten by wasps before reaching pupation size so I decided to rescue one from my garden.
I also am raising Sleepy Orange caterpillars which are smaller than Cloudless Sulpurs, but are in the Sulphur group of butterflies. I got the Sleepy Orange caterpillars at my visit to Shady Oaks Butterfly farm.
