Season-long studies of 25 rivers in southern and central New Hampshire produced a total of 112 stream species of mayflies. Time of appearance of blackwing and/or mature individuals was used to determine seasonality for each species. Different cluster analyses revealed the same pattern of faunal relationships for these rivers, with three distinct groups present: southern warm rivers, northern warm rivers, northern cold rivers.
