Emergence of adults of Edovum puttleri Grissell (Hymenoptera: Eulophidae) has a diel periodicity: most emergence occurred within 2 h of ‘lights on’ (16L:8D, 24 ± 1 °C). Males emerged 2.0 ± 3.0 h prior to females, and soon thereafter mated with emerging females. Courtship behavior did not differ between the Colombian and Mexican biotypes and was similar to that of members of the eulophid subfamily Tetrastichinae. The preoviposition period and oviposition period did not differ between biotypes. Males and females of both biotypes were long‐lived, with the longevity of females of the Mexican biotype being significantly longer than that of Colombian females. Males of both biotypes lived equally long. Mexican females produced more offspring than Colombian females, although this difference was not significant. After approximately 3 weeks, production of female offspring declined in both biotypes. A single mating was sufficient for females to produce a full complement of female offspring. Head capsule width of females correlated positively with fecundity.
