Extract

Although the species of Ophiogomphus are well defined in the adult stage their nymphs are extremely uniform in structure and are difficult to separate. This is perhaps not remarkable in view of the similarity of their habitats, all the species being shallow burrowers in running streams, usually clear, with a sandy or pebbly bottom, where they occupy the edges of currents, gentle riffles, or pools at the foot of rapids.
