The Invertebrate Community Index (Ohio EPA 1989) and Qualitative EPT richness index (the sum of the number of Ephemeroptera (mayflies), Plecoptera (stoneflies), and Trichoptera (caddisflies) taxa present) are high both upstream and downstream of the Flat Branch.

We decided not to include taxa richness (taxa identified mostly further than to the family level), EPT-index (the number of Ephemeropera, Plecoptera, and Trichopera species per sample), and other similar indices in the current analysis because of the occurrence of too many doubtful cases in older samples.

Foram analisados 78 estômagos com o grau de repleção 3, sendo identificados larvas de Diptera (Simulium, Chironomus), ninfas de Plecoptera e larva de Coleoptera aquática (Psephenus).
Diptera (73 taxa) was the most diverse insect order followed by Coleoptera (43 taxa), Odonata (31 taxa), Ephemeroptera (25 taxa), Trichoptera (23 taxa), Hemiptera (20 taxa), Plecoptera (7 taxa), Megaloptera (5 taxa), and Lepidoptera (2 taxa).
For example, adult plecoptera were not a component of the diet during autumn, but comprised 37% of the diet during the winter collection period.
Insects included Odonata (Gomphidae, Macr omiidae), Megaloptera, Trichoptera, Plecoptera, Coleoptera (Haliplidae, Dytiscidae, Gyrinidae, Psephenidae, Dryopoidea), Ephemeroptera, Hemiptera (Corixidae, Belostomatidae, Veliidae), and Diptera (Tipulidae, Chironomidae).
