Life Cycle
Males swarm during rainstorms. In eastern and southern Texas this swarming period is always late in the year, Oct-Dec. These are likely mating swarms, but I have never found a female, and it is likely that females do not fly and probably leave the soil only very briefly to attract a mate. (Ed Riley, 2008 pers. comm. to MAQ)
Females are unknown.
