Abstract
  • The external and internal morphology are considered and important morphological characters are found which relate Macrovelis to the family Mesoveliidae. Both macropterous and Brachypterous forms occur throughout the western half of the United States. The adults and nymphs are restricted to the margins of springs and streams during the reproductive period, but the adults are able to withstand quite dry conditions during the summer. Copulation and oviposition apparently take place only in the spring. Nymphs, whose behavior closely follows that of the adults, normally finish their development by Nymphs, reared in the laboratory, reached maturity in four instars.
