Using mark-release-recapture methods and linear regression analysis, daily survivorship for 3 groups of Aedes communis in a high mountain environment in the Sierra Nevada of California were estimated to be 0.90, 0.91 and 0.88, respectively. Multiple recaptures of marked females were made for up to 33 days after release. Precise estimates were not made of gonotrophic cycle lengths. However, parity data, based on dissections of samples of marked and unmarked females, suggest the length of gonotrophic cycles was between 1 and 2 weeks.
