How to use this table
Months are approximate. Flights follow warm, humid weather, often after rain, and shift from year to year and across the state. For the weather signs and what to do with a queen, read how to catch a queen.
A queen starts best in a test tube. The Scout takes a 16 mm tube as it is, and the Founder is the next room. See Start here for the order.
