A gaggle of Agnetina sp. from Chittenango Creek in Central New York. Members of the family Perlidae, these guys prefer the undersides of large stones and rocks in fast streams. In slower water they cannot obtain enough dissolved oxygen simply by staying still so they bend and straighten their legs to create currents over their gills; push-ups, so to speak. Order: Plecoptera Family: Perlidae Genus: Agnetina Chittenango Creek, NY -- source link
