The sample was <br />collected from riffle habitat using a Surber sampler. The total area sampled was <br />0.744 square meters. The sample identification number is 119288. The percentage <br />of the sample that was identified and retained was 31% of the collected sample. A <br />total of 645 individuals were removed, identified and retained. Abundance data are <br />presented as the estimated number of individuals per square meter. Notes- <br />identification to genus or species was not supported because: I - immature <br />organisms, 0 - damaged organisms, M = poor slide mount, G = gender, U = indistinct <br />characters or distribution, R = retained in our reference collection. <br /> <br />--" <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />Order <br />Phyll,n: AnneL ida <br />CLass: OLigochaeta <br />Phylum: Arthropoda <br />CLass: Arachnida <br />Troni:ddiformes <br />CLass: Insecta <br />CoLeoptera <br />Diptera <br />Diptera <br />Diptera <br />Diptera <br />Diptera <br />Diptera <br />o i ptera <br />Diptera <br />Diptera <br />Diptera <br />Oiptera <br />Ephemeroptera <br />Ephemeroptera <br />Odonata <br />Plecoptera <br />Trichoptera <br />Trichoptera <br />Trichoptera <br />Trichoptera <br />PhyLum: Nemata <br />Phylum: Vertebrata <br />CLass: Osteichthyes <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />Total: <br /> <br />24 taxa <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />FamiLy <br /> <br />Elmidae <br /> <br />ceratopogonidae <br />Ceratopogonidae <br />Chironomidae <br />Chironomidae <br />Chironomidae <br />Chironomidae <br />ElTpididae <br />Simuliidae <br />Simuliidae <br />Tipul idee <br />Baetidae <br />Heptegen i i dae <br />Coenagrionidae <br />Chloroperl idee <br /> <br />Hydropsychidae <br />Hydropsychidae <br />HydroptiLidae <br /> <br />SubfamilY/Genus/soecies <br /> <br />Life <br />Stage <br /> <br />aduL t <br /> <br />adult <br /> <br />Probezzi a <br /> <br />Larvae <br />pupa. <br />Larvae <br />Larvae <br />pupee <br />larvae <br />Larvae <br />larvae <br />pupa. <br />larvae <br />larvae <br />larvae <br />larvae <br />larvae <br />larvae <br />larvae <br />pupa. <br />larvae <br />larvae <br />larvae <br />aduLt <br /> <br />Chironominae <br />OrthocLadiinae <br />Tanypodinae <br /> <br />SimuLil.ln <br /> <br />Suwall ia <br /> <br />Chellnatopsyche <br />Hydropsyche <br /> <br />aduLt <br /> <br />Abundance Notes <br /> <br />99 <br /> <br />301 <br /> <br />9 I <br />4 u <br />198 I <br />66 <br />9 <br />74 <br />443 <br />71 <br />9 <br />155 <br />41 <br />9 I <br />960 I <br />9 I <br />14 0 <br />4 <br />4 U <br />4 <br />9 <br />138 <br />95 <br /> <br />u <br /> <br />2725 individuals <br />
