Abstract
Biology of Misumenops celer (Hentz) was studied in the laboratory. Observations were made on mating behavior, oviposition, hatching, and development of different instars. Sexual dimorphism was marked; the male was about half the size of the female. The male mated with more than 1 female, while the female mated only once. The number of egg sacs per female varied from 1 to 3, and the number of eggs per sac varied from 55 to 234. Males reached maturity after 4 or 5 instars, and females attained the adult stage after 6 or 7 instars. The 1st instar remained inside the egg sac. The period from egg to attainment of the adult stage was 85–169 days for males and 118–311 days for females. The feeding behavior and food preference of M. celer spiders in the laboratory and population fluctuation in the alfalfa field also were studied.
