[ 5 ] Around half of all mayfly species whose reproductive biology has been described are parthenogenetic (able to asexually reproduce), including both partially and exclusively parthenogenetic populations and species.
The larvae of dobsonflies live along the rocky bottoms of streams. Chiefly active during the night , they ambush prey in the middle of riffles which supply plenty of oxygen and stir up prey.

The larvae move around inside the tubes and this helps maintain the water current; the lower the oxygen content of the water, the more active the larvae need to be. This mechanism enable caddisfly larvae to live in waters too low in oxygen content to support stonefly and mayfly larvae. [19]
Tomah mayflies live in the adult stage for only 1–9 days, as they mate and lay eggs. They do not feed in the adult stage. [4] The Tomah Mayfly is a natural prey of Brook Trout (Salvelinus fontinalis).
