//Salticella fasciata// has a long season. Presumably activity is related to the activity of the host snails. In an environment where host populations are relatively small and of a high mortality, evolutionary pressures would favour those individuals which oviposited on the last active snails in each season, that is before the snails aestivate. Warm, dry days in early October may be the best times to observe them. //Salticella fasciata// has a long season. Presumably activity is related to the activity of the host snails.

-It has been tried as a biological control agent against snails such as //Theba pisana//, //Cernuella virgata//, //Cochlicella acuta// and //C. barbara// which are species from the Mediterranean region which have become pests in Australia. Although it would lay eggs in in the umbilicus of //Theba// it was found to be ineffective in killing the snail.
