Odonata abundance given as number of individuals per meter squared. Only study sites and microhabitats where nymphs were recorded are given. Microhabitat abbreviations: MESO = mesolithal (hand-sized cobbles); MICRO = microlithal (coarse gravel); AKA = akal (fine to medium-sized gravel); PSA = psammal (sand); XYL = xylal (woody debris); ARG = argyllal (clay); TECHNO = technolithal (artificial blocks); MACROP = both submerged and emergent macrophytes. * - juvenile instars not identified to species level.
