DescriptionThe life cycle and production of Skwala parallela, a perlodid stonefly, was investigated in a third-order Colorado montane stream. The species exhibited a univoltine life cycle with a distinct cohort. Small nymphs appeared in May. Rapid growth was exhibited throughout summer and autumn. During winter, growth slowed somewhat but was continuous until April. Maximum density of 34 nymphs/m2 occurred in July. Based upon the instantaneous growth method, annual production was 395 .3 mg/m2 or 3 .95 kg/ ha dry weight with a P/B ratio of 4.4.
