The bug of the week is Dinocras cephalotes, a stonefly (Plecoptera). Plecoptera is Latin for ‘braided-wings’, which is a fitting description given this species appearance. Stoneflies have four wings, which fold neatly over its abdomen. Stoneflies are predominately found in cold water, require plenty of dissolved oxygen, and are sensitive to pollution – making their presence a reliable indicator of good water quality. Adults are generally short lived. When present, the nymphs are easy to spot by hand-searching under stones in clean rivers and streams.
