ABSTRACT: Misumenops pallidus life cycle and recruitment were studied under both laboratory and field conditions during two consecutive years. The life cycle included the egg stage, seven or eight juvenile instars and the adult stage. The first three instars developed within the egg sac, while the others developed as free living individuals. Total body length increased from 3.2mm in the 3rd instar up to 14mm in adult females in average, and from 3.2mm up to 9mm in males. Predatory rate increased according growth and maturity in females (females would consume 81% of all preys in the adult stage). Longevity of males and females as adults averaged 69.2 (± 30.76) and 161.3 (± average, and from 3.2mm up to 9mm in males. Predatory rate increased according growth and maturity in females (females would consume 81% of all preys in the adult stage). Longevity of males and females as adults averaged 69.2 (± 30.76) and 161.3 (± average, and from 3.2mm up to 9mm in males. laboratory and field conditions during two consecutive years.
