Abstract

Many environmental factors may influence the activity pattern of scorpions in arid ecosystems. We investigated the seasonal variations of Paruroctonus marksi scorpion activity in the Mojave desert (California, USA). Black light census were carried out within two 100 ×100 m plots from August 2017 to September 2018. The majority (85%) of scorpions were found in open areas compared with being in vegetation. The probability of surface occurrence of P. marksi does not appear to be a random event. Surface activity of these scorpions was positively correlated with both water vapor pressure and soil temperature, while moon illumination was not a factor in P. marksi foraging in open area.
