    Rearing of animals from one generation to the next is important in many biological studies. In this study, we aimed to develop efficient methods for rearing multiple generations of orb-web spiders (Cyclosa argenteoalba), testing three methods. First, we examined isolated rearing with aphid supplied by hand. Second, we tested mass rearing. We also collected various insect species from the field using light trap and supplied them by hand. Both methods failed, perhaps because of the inappropriate aphid (Uroleucon formosanum) and insufficient quantity of prey supplied in the first and second tests, respectively. For the third method, we mass reared with abundant prey directly supplied from light traps into the terrariums located outside. This method successfully raised hatchlings to adults, and the eggs produced from these adults also matured. The development time of wintering and non-wintering cohorts was 150.2‐195.0 days and 24.0‐76.3 days, respectively.
