• Callibaetis floridanus

  small minnow mayfly

  Callibaetis floridanus is a small minnow mayfly (Ephemeroptera: Baetidae) native to North and Central America. The species inhabits diverse aquatic environments including coastal ponds subject to saltwater intrusion and temporary wetlands (playas) in arid regions. Research demonstrates significant physiological plasticity in ion regulation, with populations capable of acclimating to salinities ranging from 113 to 9,921 µS/cm. Naiad development averages approximately 24 days from egg hatch to adulthood.
