                RESEARCH REPORTING SERIES

Research reports of the Office of Research and Development, U.S. Environmental
Protection Agency, have been grouped into nine series. These nine broad cate-
gories were established to facilitate further development and application of en-
vironmental technology.  Elimination  of traditional grouping was  consciously
planned to foster technology transfer and a maximum interface in related fields.
The nine series are:

      1    Environmental Health Effects Research
      2.   Environmental Protection Technology
      3.   Ecological Research
      4.   Environmental Monitoring
      5.   Socioeconomic Environmental Studies
      6.   Scientific and Technical  Assessment Reports (STAR)
      7.   Interagency  Energy-Environment Research and Development
      8.   "Special"  Reports
      9.   Miscellaneous Reports

This report has been assigned to the ENVIRONMENTAL MONITORING series.
This series describes research conducted to develop new or improved methods
and  instrumentation for the identification and  quantification of environmental
pollutants at the lowest conceivably significant concentrations. It also includes
studies to determine the ambient concentrations of pollutants in the environment
and/or the variance of pollutants as a function of time or meteorological factors.

                                  FOREWORD

     Environmental measurements are required to determine the quality of
ambient water, the character of effluents, and the effects of pollutants
on aquatic life.  The Environmental Monitoring and Support Laboratory -
Cincinnati conducts research to develop, evaluate, and promulgate methods
to:

     *  Measure the presence and concentration of physical, chemical,
        and radiological pollutants in water, wastewater, bottom sediments,
        and solid waste.
     *  Concentrate, recover, and identify enteric viruses, bacteria,
        other microorganisms in water.
     *  Measure the effects of pollution on freshwater, estuarine, and
        marine organisms, including the phytoplankton, zooplankton,
        periphyton, macrophyton, macroinvertebrates, and fish.
     *  Automate the measurement of physical, chemical, and biological
        quality of water.
     *  Conduct an Agency-wide quality assurance program to assure
        standardization and quality control of systems for monitoring
        water and wastewater.

     The effectiveness of measures taken to protect the biological
integrity of the Nation's surface waters is dependent upon our knowledge
of the environmental requirements of aquatic organisms and our understand-
ing of the complex relationships that prevail in aquatic ecosystems.
This study focuses on an important group of aquatic insects—the
Ephemeroptera (mayflies).  The nymphs of mayflies occur in all types  of
freshwater and are important components of aquatic food-webs.  Mayfly nymphs
are generally considered pollution sensitive, but some species have been
found to be tolerant to specific kinds of pollution.  The nymphs and  adults
are also important in the diets of many fish species.

     This report is the third in a series of reports in preparation on the
environmental requirements and pollution tolerance of aquatic organisms.
Water quality profiles have been developed to serve as companions to  the
EPA biological methods manual and identification manuals to assist biologists
in evaluating data collected during studies concerning the effects of toxic
substances and other pollutants on the structure of indigenous communities
of aquatic organisms.

                           ABSTRACT
       Data on the environmental requirements and pollution
tolerance of 400 species of mayflies (Insecta: Ephemeroptera)
from the United States and Canada were compiled from 200 sources.
The following ecological parameters were considered: pH,
nutrients, organic pollution, oxygen concentration, temperature,
turbidity, current, general and specific habitats, season of
emergence, feeding behavior, and geographical distribution.  It
is suggested that this compilation be used as a guide to assist
in evaluating data on macroinvertebrates collected in ambient
water monitoring and studies of the effects of pollution on
aquatic life.

                               INTRODUCTION

     Mayflies are one of the most important groups of aquatic insects and
spend the major part of their lives as nymphs in the water, leaving it only
to mate and lay eggs.  They often tolerate only an extremely narrow range of
environmental conditions and may be quite sensitive to small changes in
their immediate environment.  The absence, or presence, of a particular
species in a body of water can often yield much information about the quality
and environmental characteristics of that water if the biology of the species
is adequately known.  With growing concern for and interest in the quality
of aquatic systems, increasing attention has recently been directed to these
organisms and their possible use as biotic indicators of water quality. For
this reason this book has been conceived as an aid to help biologists focus
their attention on the relationship between mayflies and their aquatic
environment and facilitate studies on water quality using them as biotic
indicators.

     This report is intended to be used as a source of data on the water
quality requirements and pollution tolerance of the Ephemeroptera.  It is not
intended to be a definitive work and does not include information from the
total available literature.  Instead, we have tried to include representative
examples of the literature on mayflies and provide a starting point for
further investigation by the interested reader.  Because of the nature of
the literature on Ephemeroptera, much leeway had to be taken in the inter-
pretation of the data contained in that literature.  The wise user will refer
to the primary literature to determine the extent of the leeway in interpre-
tation.  One must also bear in mind that the ecological parameter ranges
given may not be outer limits, but may merely reflect sampling bias, and
that the true ecological tolerances of the organism may be much greater than
indicated.  Because related species, even within the same genus, often differ
in water quality requirements and pollution tolerance, the importance of
accurate determination of species cannot be overemphasized.

     Keys to the North and Central American families, subfamilies, and
genera of mayflies based on the nymphs and adults are given in Edmunds,
Jensen, and Berner (1976).  These authors also give discussions of nymphal
habitats and habits, life histories, and adult habits.  A list of all des-
cribed species for each genus and their general distribution is given.

     Few keys to the species of mayflies of the United States and Canada
exist.  For such keys to be really meaningful, they should have been develop-
ed in conjunction with taxonomic revisions of genera.  Few such taxonomic
revisions exist; those that have been completed include Ephemerella (Allen
and Edmunds 1959, 1961a, 1961b, 1962a, 1962b, 1963a, 1963b, 1965).  Steno-
nema (Lewis 1974), and the Ephemeroidea (McCafferty 1975).  Useful species

-------
keys are also included in Needham, Traver, and Hsu (1935) and the va*   .
state studies listed below:  Florida (Berner 1950), Illinois (Buries j.»w
California  (Day 1956) , and Idaho  (Jensen 1966) .
     The sources  for  the data given in the ecological profiles are ^s^
in  the  "Reference"  column at the  top of the profile sheet by a number wnic
corresponds  to  a  source in  the  section entitled "Selected References rot
Mayfly  Ecology  Profiles".
      This  book is intended to be used as  a working  tool by biologist
 has been designed to allow updating of the ecological profile  sheets  by  tne
 user as new information is obtained from  the literature or the llej-a:
 Blank sheets have been included at the end to allow addition of species  not
 originally part of this compilation.  It  is  hoped that this  continued up-
 dating by  individual users will greatly increase the effectiveness or tnis
 publication.

16. ABSTRACT
      Data  on the environmental requirements  and pollution tolerance- of  400  species
 of mayflies (InsectarEphemeroptera) from  the United States and Canada were  compiled
 from 200 sources.  The following ecological  parameters were considered:   pH,
 nutrients, organic pollution, oxygen concentration, temperature, turbidity,  current,
 general  and specific  habitats, season  of  emergence, feeding behavior, and geo-
 graphical  distribution.   It is suggested  that this compilation be  used  as a guide
 to assist  in evaluating  data on macroinvertebrates collected in ambient water
 monitoring and studies of the effects  of  pollution on aquatic life.
