The mature larvae of 10 species of aquatic insects (Boyeria vinosa say, Ophiogomphus rupinsulensis walsh, Pteronarcys dorsata (say), Taeniopetryx maura (pietet), Acroneuria lycorias (newman), Isogenus frontalis newman, Ephemerella subvaria mcdunnough, Stenonema rubrium (mcdunnough), Brachycentrus americanus (banks), and Hydropsyche betteni ross) were tested in the laboratory to determine their relative tolerance to low pH. The ph at which 50% died after 96 hours was recorded as the lethal pH. These values ranged from pH 4.65 for mayflies to pH 1.50 for caddisflies.
