Arthropods of Elm Fork Preserve
Arthropods of Elm Fork Preserve Arthropods are characterized by having jointed limbs and exoskeletons. They include a diverse assortment of creatures: Insects, spiders, crustaceans (crayfish, crabs, pill bugs), centipedes and millipedes among others. Column Headings Scientific Name: The phenomenal diversity of arthropods, creates numerous difficulties in the determination of species. Positive identification is often achieved only by specialists using obscure monographs to ‘key out’ a species by examining microscopic differences in anatomy. For our purposes in this survey of the fauna, classification at a lower level of resolution still yields valuable information. For instance, knowing that ant lions belong to the Family, Myrmeleontidae, allows us to quickly look them up on the Internet and be confident we are not being fooled by a common name that may also apply to some other, unrelated something. With the Family name firmly in hand, we may explore the natural history of ant lions without needing to know exactly which species we are viewing. In some instances identification is only readily available at an even higher ranking such as Class. Millipedes are in the Class Diplopoda. There are many Orders (O) of millipedes and they are not easily differentiated so this entry is best left at the rank of Class. A great deal of taxonomic reorganization has been occurring lately with advances in DNA analysis pointing out underlying connections and differences that were previously unrealized. For this reason, all other rankings aside from Family, Genus and Species have been omitted from the interior of the tables since many of these ranks are in a state of flux. -
Funnel Weaver Spiders (Funnel-Web Weavers, Grass Spiders)
Colorado Arachnids of Interest Funnel Weaver Spiders (Funnel-web weavers, Grass spiders) Class: Arachnida (Arachnids) Order: Araneae (Spiders) Family: Agelenidae (Funnel weaver Figure 1. Female grass spider on sheet web. spiders) Identification and Descriptive Features: Funnel weaver spiders are generally brownish or grayish spiders with a body typically ranging from1/3 to 2/3-inch when full grown. They have four pairs of eyes that are roughly the same size. The legs and body are hairy and legs usually have some dark banding. They are often mistaken for wolf spiders (Lycosidae family) but the size and pattern of eyes can most easily distinguish them. Like wolf spiders, the funnel weavers are very fast runners. Among the three most common genera (Agelenopsis, Hololena, Tegenaria) found in homes and around yards, Agelenopsis (Figures 1, 2 and 3) is perhaps most easily distinguished as it has long tail-like structures extending from the rear end of the body. These structures are the spider’s spinnerets, from which the silk emerges. Males of this genus have a unique and peculiarly coiled structure (embolus) on their pedipalps (Figure 3), the appendages next to the mouthparts. Hololena species often have similar appearance but lack the elongated spinnerets and male pedipalps have a normal clubbed appearance. Spiders within both genera Figure 2. Adult female of a grass spider, usually have dark longitudinal bands that run along the Agelenopsis sp. back of the cephalothorax and an elongated abdomen. Tegenaria species tend to have blunter abdomens marked with gray or black patches. Dark bands may also run along the cephalothorax, which is reddish brown with yellowish hairs in the species Tegenaria domestica (Figure 4). -

Distribution of native European spiders follows the prey attraction pattern of introduced carnivorous pitcher plants Axel Zander*, Marie-Amélie Girardet and Louis-Félix Bersier Department of Biology – Ecology and Evolution, University of Fribourg, Chemin du Musée 10, Fribourg CH-1700, Switzerland * E-mail: [email protected] Abstract Carnivorous plants and spiders are known to compete for resources. In North America, spiders of the genus Agelenopsis are known to build funnel-webs, using Sarracenia purpurea pitchers as a base, retreat and storage room. They also very likely profit from the insect attraction of S. purpurea. In a fen in Europe , S. purpurea was introduced ~65 years ago and co-occurs with native insect predators. Despite the absence of common evolutionary history, we observed native funnels-spiders (genus Agelena) building funnel webs on top of S. purpurea in similar ways as Agelelopsis. Furthermore, we observed specimen of the raft-spider (Dolmedes fimbriatus) and the pygmy-shrew (Sorex minutus) stealing prey-items out of the pitchers. We conducted an observational study, comparing plots with and without S. purpurea, to test if Agelena were attracted by S. purpurea, and found that their presence indeed increases Agelena abundance. Additionally, we tested if this facilitation was due to the structure provided for building webs or enhanced prey availability. Since the number of webs matched the temporal pattern of insect attraction by the plant, we conclude that the gain in food is likely the key factor for web installation. -

PLS 116 How to Identify Or Misidentify the Hobo Spider
PLS 116 How to identify (or misidentify) the hobo spider Rick Vetter and Art Antonelli Since the late 1980s, many people in Washington have been concerned about the hobo spider because it has been blamed as the cause of dermatologic wounds. We offer here a guide to help identify some medium-sized Washington spiders found in homes. However, keep in mind that without a microscope you may not be able to identify hobo spiders and may have to settle for determining that your spider is NOT a hobo spider. This may be frustrating and not the goal you had in mind, however, quite often the question is not "What spider do I have?" but "Do I have a hobo spider?" You should be able to learn enough to eliminate many spiders from consideration without a microscope and sometimes with just the naked eye. Most people want a world with simple black/white answers but you must realize that there many shades of gray in between and this is the reality of spider identification. This publication was initiated discriminatory skills up a notch, with because there is no currently a little practice, you should be able to available guide to spider confidently determine the identification for the person with characteristics of spiders that are limited arachnological skills. Most of NOT hobo spiders, which will be the the previous guides for hobo spider majority of the medium-sized spiders identification try to give a simplistic you will encounter. way to discern hobo spiders. We have found that many well- intentioned people misconstrue the information and confidently misidentify their non-hobo spider as a hobo. -

MOCK (Under the Direction of Alan Harvey) ABSTRACT Anelosimus studiosus (Theridiidae) is a subsocial spider that has a diverse arthropod fauna associated with its webs. From south Georgia, I identified 1006 arthropods representing 105 species living with A. studiosus , and 40 species that were prey items from 250 webs. The arthropods seen in A. studiosus webs represented a distinct community from the arthropods on the tree. I found that Barronopsis barrowsi (Agelenidae) and Frontinella pyramitela was similar to A. studiosus in web structure and that B. barrowsi webs contained multiple arthropods. Also, previously known as asocial, B. barrowsi demonstrated sociality in having multiple adults per web. Lastly, the inquiline communities in the webs of A.studiosus and B.barronopsis contained many different feeding guilds, including herbivores, omnivores, generalist predators, kleptoparasites, and aranievores. -

Surprisingly, despite their great diversity of body plans, there is no unambiguous evidence that any crustacean is venomous. We provide the first conclusive evidence
