- Extensive field studies in 1965—1966 in a small woodland impoundment in Guilford County, North Carolina indicated the duration of the life cycle of Lestes eurinus was about 1 yr. Rapid larval growth occurred from July to mid—October with development being arrested by late October. The population overwintered in the three stages preceding the ultimate instar. Larval growth was resumed in March and progressed rapidly until emergence. Emergence began on May 1, was rather unsynchronized, lasted for 2 months, and was temperature—dependent. Oviposition occurred during June and July; the females wee observed to oviposit only in the abundant emergent bur—reed Sparganium americanum. Eclosion occurred from mid—July until mid—August. The larvae grew rapidly in the succeeding months and attained the overwintering stages by October.
