Adults normally do not feed, but some species are known to feed on nectar. They can be found flying around at night, because they are nocturnal, and can be caught using light traps. Otherwise, adults can be found during the day inside of vegetation where they remain quiescent until night. After mating, eggs are laid in a gelatinous mass under rocks, on the water surface, or on floating objects in a stream. This gelatinous mass helps to protect the eggs by ensuring they do not desiccate.
