After the start of oviposition in the laboratory (age 3 d), the moths were released into the cages at the beginning of the scotophase at a density of 100 pairs (100 males and 100 females) per cage and maintained for 3 d for egg-deposition on the plants.

From tapes, we quantified nightly activity as the number of spiders simultaneously running during a one-minute period at 10-min intervals, for 54 periods covering crepuscular light and the eight hours of scotophase.
Blem and Killeen (1993) reported that Agkistrodon piscivorus and Nerodia taxispilota exhibited higher scotophase metabolic rates in snakes that were acclimated to a reverse photoperiod and tested in complete darkness.
Mishra and Omkar (2004) observed that the major foraging activity and field presence levels of Propylea dissecta (Mulsant) (Coleoptera: Coccinellidae) occur in the photophase while peaks of rhythm of mating, oviposition, hatching and moult occur in scotophase, then supposing that the concentration of life events other than foraging in the same moments could be a survival strategy of evolutionary significance.
