| 2009: 2008: 2007: 2006: 2005: 2004: 2002: | U.S.A. (Arizona) 2007 5–7 October, 2007: Funded by the REVSYS grant. Volunteer Zach Valois and Kelsey Neeley travelled ca. 1,200 miles through central and northern Arizona, sampling biotic communities from the lower Colorado plateau desert, upper and lower Sonoran, chaparral, and petran montane coniferous forest. More than fifty scorpion specimens, representing three genera and five species, were collected. 14 September, 2007: Funded by the REVSYS grant. Naturalists Jim Bockowski, Donna Zeidel and Bill Schol accompanied volunteer Manny Rubio (zoologist living in Tucson) to search for Serradigitus agilis at the type locality. The description of the type locality is ambiguous and indefinite so the day was spent looking for suitable habitat that would be hunted with black-lights after dark. Fourteen potential sites (rock-faced road cuts with numerous, small, vertical fissures) were selected. No sites with a northern exposure were identified along the selected four mile stretch of road. Black-lighting (19h40-21h30) yielded a dozen specimens from five sites. All S. agilis were located from one to four meters above the ground on open, vertical faces; none were observed in habitat under canopy. Their diminutive size and quickness to retreat into small cracks made capturing S. agilis problematic; some escaped and others were crushed. A few likely locations, devoid of S. agilis, were inhabited by Centruroides exilicauda. One Pseudouroctonus apacheanus was found and appears to be a western range extension. A single Diplocentrus spitzeri was located among scree at the base of a S. agilis site. Vaejovis spinigerus were abundant (more than 40 specimens) along the ground litter in open and canopied places at all the sites searched; several were collected. | |
