Juvenile mayflies are aquatic insects. Most species feed on detritus and algae but a few are carnivorous. Adult lifespans are generally short, ranging from a few hours to several days for most species. In some areas of the country, large short-lived mating swarms of adults occur. Because of the brief adult lifespans and hence the uncertainty of finding adults for identification, juveniles are often collected and raised to maturity in order to determine their exact species.
I have included the following picture of the aquatic juvenile for reference only.
