Biting collections from June 18 to August 23, 1975 yielded 3,145 Aedes sollicitans females of which 1,240 were dissected. There were 450 nulliparous, 664 1-parous, 109 2-parous and 17 3-parous mosquitoes. Both the total catch and the component age groups exhibited bimodal patterns of activity. Maximum activity occurred within 15 to 30 minutes of civil twilight at dusk and dawn. The total number of females collected from the dawn period was significantly greater than for the dusk period. No difference in activity of the nulliparous, or 1-parous and 3-parous females was noted between dusk and dawn periods, but a significant difference was noted in the abundance of 2-parous females from the dawn period.
