Pitfall traps were set and visual observations made along regularly walked transects to assess the patterns of surface activity of Ommatoiulus moreletii in open grassland and dry sclerophyllous woodland in South Australia. Active O. moreletii were most commonly seen and trapped in autumn, to a lesser extent in spring, occasionally in summer and rarely in winter. Day to day variations in activity were related to changes in temperature and moisture. The activity of older stadia was greater than that of younger stadia.
