Abstract. The locomotor activity of the Chilean recluse spider Loxosceles laeta (Nicolet, 1849), and the spitting spider, Scytodes globula Nicolet, 1849, were studied in the laboratory under controlled conditions (LD 12:12). In Chile, these are two common synanthropic spiders which share a microhabitat and show extensive thermal niche overlap.
