I found eight caterpillars I later found out were those of the orange sulphur butterfly. Today, I realized they were pupating. For how long should I expect to wait before they emerge as butterflies?

Brian,  
 
I will not take long for the butterfly to emerge from the pupae. It is all temperature dependent. Under outdoor conditions it will probably take 10-12 days. A lot of changes occur in that pupae in a short period of time.

The butterflies should emerge in about 7 to 10 days depending on the temperature. The entire lifecycle of the alfalfa caterpillar is completed from egg to adult butterfly within a single cutting cycle of the alfalfa or between 30 to 45 days depending on the temperature during development.
