Parson Spiders
Colorado Arthropod of Interest Parson Spiders Scientific Name: Herpyllus species Order: Araneae (Spiders) Family: Gnaphosidae (Ground Spiders) Identification and Descriptive Features: The parson spiders are moderately large spiders (female 6.5-13mm; male 4.5-6.5mm) with overall black color. A broken white or silvery stripe prominently marks the back of the abdomen. (This marking is reminiscent of the old style neck band cravat formerly worn by parsons and others of the ministry.) A wide shiny band of reflective silvery hairs occurs on the cephalothorax. The legs that are brown, banded with black and relatively long; parson spiders are fast runners. Distribution in Colorado: Four species are known from Colorado: Herpyllus bubulcus, H. ecclesiasticus (eastern parson spider), H. Figures 1, 2. Top and side views of two hesperolus, and H. propinquus (western parson different spieces of parson spider (Herpyllus spider). At least one Herpyllus species can likely spp.). Lower photograph courtesy of David be found in any Colorado county and human- Shetlar, The Ohio State University. assisted transfers of these spiders is likely common. Life History and Habits: Parson spiders can be common invaders of buildings in late summer and early fall. Indoors they may be found crawling on walls and they can move quickly, often running in a zig-zag pattern. They do not breed indoors. The parson spiders are active at night and in twilight hours. During the day they seek cover provided by loose bark, boards or other sheltering sites and often form a silken retreat within which they rest. Life history is poorly known. Eggs of at least some species are produced in late summer and early fall. -

Pinyon Pine Mortality Alters Communities of Ground-Dwelling Arthropods
Western North American Naturalist 74(2), © 2014, pp. 162–184 PINYON PINE MORTALITY ALTERS COMMUNITIES OF GROUND-DWELLING ARTHROPODS Robert J. Delph1,2,6, Michael J. Clifford2,3, Neil S. Cobb2, Paulette L. Ford4, and Sandra L. Brantley5 ABSTRACT.—We documented the effect of drought-induced mortality of pinyon pine (Pinus edulis Engelm.) on com- munities of ground-dwelling arthropods. Tree mortality alters microhabitats utilized by ground-dwelling arthropods by increasing solar radiation, dead woody debris, and understory vegetation. Our major objectives were to determine (1) whether there were changes in community composition, species richness, and abundance of ground-dwelling arthro- pods associated with pinyon mortality and (2) whether specific habitat characteristics and microhabitats accounted for these changes. We predicted shifts in community composition and increases in arthropod diversity and abundance due to the presumed increased complexity of microhabitats from both standing dead and fallen dead trees. We found signifi- cant differences in arthropod community composition between high and low pinyon mortality environments, despite no differences in arthropod abundance or richness. Overall, 22% (51 taxa) of the arthropod community were identified as being indicators of either high or low mortality. Our study corroborates other research indicating that arthropods are responsive to even moderate disturbance events leading to changes in the environment. These arthropod responses can be explained in part due to the increase in woody debris and reduced canopy cover created by tree mortality. RESUMEN.—Documentamos el efecto de la mortalidad causada por la sequía del pino piñonero (Pinus edulis Engelm.) sobre comunidades de artrópodos subterráneos. Utilizamos tres variantes en el microhábitat de los artrópodos incrementando la radiación solar, desechos de madera muerta y vegetación baja. -

Introduction Although this guide is primarily for spiders, harvestmen, scorpions, ticks, and sun spiders are Spiders belong in the Phylum Arthropoda, Class briefly mentioned. Arachnida, Order Araneae. These common arachnids are found in grasslands, forests, orchards, cultivated fields, backyards, gardens, empty lots, parks, and homes. There are some 570 genera and 3,700 species of spiders in North America, north of Mexico. According to an Oklahoma State University checklist at least some 187 genera and 432 species were recorded in the state. Cokendolpher and Bryce (1980) examined arachnid specimens collected at the Wichita Mountains Wildlife Refuge by various groups between 1926 and 1978. Their work yielded a total of 182 arachnid species, of which 170 were spiders. Figure 1.

Critical analysis of existing spider species lists for Wisconsin, Michigan, Ohio. Indiana and Illinois reveals 900 species recorded from the five-state region (284 genera, 40 families). All non- native, Palearctic, or otherwise questionable species records were scrutinized, and their status is discussed. The most speciose families in the region are the Linyphiidae (almost 24% of species), Salticidae (10.3%), Theridiidae (8.9%), Lycosidae (8.8%), and Araneidae (7.7%). All sources used for spider species names and species records are unambiguously quoted. Spider species records are presented in tables allowing comparison of family composition among the states, and prediction of number of heretofore unrecorded species. Richness among states is analyzed and found to be dependent on varying degrees of sampling effort. As a new tool, a Spider Species Name Concordance Table allows tracking previously published spider species names to the currently valid name of every species record.
