Life cycle of the cicada killer wasp

Complete metamorphosis

Adults emerge from the soil in summer.  Males and females will feed, mate and begin making small burrows about 6 inches deep in the soil surface preparing for when the female lays her eggs.  The female will search for cicadas in or near trees.  They will sting the cicada causing paralysis then drag the cicada or multiple cicadas into one burrow, lay one egg, then seal burrow so development can occur.  The larva will begin feeding after hatching 2-3 days later.  Approximately a week later pupation is initiated and continues through the winter until the adult emerges the following June.  One generation each year.
