Figure 4: Scorpion excursions. a. Scorpion 1 excursions. b. Scorpion 2 excursions. n1 = night 1 excursions; n2 = night 2 excursions. Arrows are 10 cm long and point north. Upslope is toward the top of the figures. All scorpion 1 and 2 excursions, except scorpion 2's third excursion on night 2, occurred within seconds of an arthropod passing. A cricket, placed near the burrow of scorpion 1, elicited excursion 1 on night 2.
