How long do mason bees live?



The lifecycle of a mason bee takes about 1 year. They begin as eggs in the spring, and develop from egg to larva to pupa to adult bee in a cocoon from June to September. Once in cocoon, they hibernate until temperatures reach around 58 degrees (typically the end of March/beginning of April). The males will fly for about 3 weeks and the females typically fly for 7-8 weeks. So even though we only see them flying around for a few months out of the year, a single mason bee lives for one year.
