Los Bańos, Laguna, Philippines *For Correspondence: [email protected] ABSTRACT Many orb-web building spiders such as the garden spider Argiope luzona (Walckenaer, 1841) add conspicuous, white zigzag silk decorations termed stabilimenta onto the central portion of the webs. We studied the features of the web of this species by examining the stabilimenta, variations in form and quantity, presence and absence of stabilimentum and structure to be able to understand the nature of web building especially the factors that affect the nature of the built web. Field observations reveal that the stabilimenta of A. luzona are mainly discoid or cruciate which significantly depended on body size. Smaller individuals (body size < 0.6 cm) produced mainly discoid stabilimenta and larger individuals (body size > 0.6 cm) produced strictly cruciate stabilimenta that are 1-armed, 2-armed, 3-armed, 4- armed, or 5-armed. Results also showed that the spiders’ body size was positively correlated to the number of stabilimentum arms, length of upper arms and to the length difference between upper and lower arms.

Unlike insects spiders show much fewer diversifications in terms of morphology and foraging strategies. Species of different families possess a very similar body plan and all feed almost exclusively on insects (Foelix 1996). Nevertheless, spiders conquered a broad spectrum of habitats. From the evolutionary point of view these order- specific features demonstrate that “They are obviously doing something right” (Craig 2003).

  • Web-Site Selection by Orb-Web Spiders, Particularly Argiope Aurantia Lucas
    Anim. B eh a v 1977,25,694-712 WEB-SITE SELECTION BY ORB-WEB SPIDERS, PARTICULARLY ARGIOPE AURANTIA LUCAS By FRANK ENDERS* North Carolina. Mental Health Research Division, Raleigh, N.C. 27611 Abstract. The entire behaviour of selection of web-site by Argiope aurantia is briefly described. Data on the following characteristics of the location of webs are provided: height in the vegetation, orientation of lean of web, use of different types of vegetation within a habitat, and abundance of insects at the site. In the laboratory, araneid spiders tested prefer higher light intensity and low humidity. The choice of height by immature A. aurantia is experimentally related to the height at which the spider begins its search for a web-site (point of release in cage), and to the covering of the cage (reduction of wind). Differences of these animals with Argiope trifasciata Forskal and with adult A. aurantia released in cages are reported and related to differential use of microhabitats. The behaviour of selection of web­ site is discussed with regard to availability of prey and to predation pressure, comparisons being made to other groups of animals. The habitat of an animal is the place where it Here, I present original observations on the lives (Odum 1959).

  • Predation by Argyrodes (Theridiidae) on Solitary and Communal Spiders*
    PREDATION BY ARGYRODES (THERIDIIDAE) ON SOLITARY AND COMMUNAL SPIDERS* BY DEBORAH SMITH TRAIL Section of Neurobiology and Behavior Department of Entomology Cornell University Ithaca, N.Y. 14853 INTRODUCTION Species of Argyrodes Simon (Theridiidae) are best known as kleptoparasites in the webs of other spiders, particularly in the tropics (Exline 1945; Exline and Levi 1962; Kaston 1965; Vollrath 1976, 1978, 1979). They live in or near the webs of their hosts and take prey from the host's web. The methods used to take prey from the host vary for different species of Argyrodes and different host species. In some cases the Argyrodes take food which the host has left at the capture site or in the hub of the web. They may also take small trapped insects which are not normally used by the host (Robinson and Olazarri 1971). In other cases the kleptoparasites feed from prey while it is still in the jaws of the host spider (Robinson and Robinson 1973). Temperate zone Argyrodes are also found in the webs of other spiders, where they are generally considered to be commensal or kleptoparasitic. However, some temperate zone species of Argy- rodes have been observed preying on their hosts. Argyrodes fictilium (Hentz) was observed feeding on an Araneus sp. host (Exline and Levi 1962) and on Frontinella communis (Hentz) (Archer 1946). Lamore (1958) reported A. trigonum (Hentz) feeding on Mecynogea lemniscata (Walckenaer) and Wise (in press) reports the results of an experimental study of the impact of A. trigonum on a population of Metepeira labyrinthea (Hentz.) It may be that predation on other spiders is more important than kleptoparasitism for some temperate Argyrodes.

  • Golden Silk Spider, Trichonephila Clavipes (Linnaeus) (Arachnida: Araneae: Tetragnathidae)1 H
    EENY229 Golden Silk Spider, Trichonephila clavipes (Linnaeus) (Arachnida: Araneae: Tetragnathidae)1 H. V. Weems, Jr. and G. B. Edwards, Jr.2 Introduction make webs between rows in soybean fields (Whitcomb and Edwards unpublished). In Florida and other southeastern states, the golden silk spider, Trichonephila clavipes (Linnaeus), a large orange and brown spider with feathery tufts on its legs, is well known to most native southerners. It is particularly despised by hikers and hunters, as during late summer and fall the large golden webs of this species make a sticky trap for the unwary. However, as is typical with most spiders, there is little real danger from an encounter with the golden silk spider. The spider will bite only if held or pinched, and the bite itself will produce only localized pain with a slight redness, which quickly goes away. On the whole, the bite is much less severe than a bee sting. Typically, the webs are made in open woods or edges of dense forest, usually Figure 1.

    BEHAVIORAL ECOLOGY OF WASP-SPIDER INTERACTIONS: THE ROLE OF WEBS, CHEMICALS, AND DECEPTION A Dissertation submitted to the Faculty of the Graduate School of Arts and Sciences of Georgetown University in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Biology By Divya Bellur Uma, M.S. Washington, D.C. April 14, 2010 Copyright 2010 by Divya Bellur Uma All Rights Reserved ii BEHAVIORAL ECOLOGY OF WASP-SPIDER INTERACTIONS: THE ROLE OF WEBS, CHEMICALS, AND DECEPTION Divya Bellur Uma, M.S. Dissertation Advisor: Martha R. Weiss, Ph.D. ABSTRACT Predator-prey interactions are integral to the maintenance of community structure and function. Predators and prey use multiple cues to detect and assess each other, and identification of these cues is necessary to understand how selection operates to shape predator-prey interactions. Mud-dauber wasps (Sphecidae), one of the main predators of spiders, prefer araneids (two-dimensional web-building spiders) over derived araneoids, (three-dimensional web-building spiders). Predation pressure by spider-hunting wasps is considered a key factor in the evolution of 3D web-building spiders. However, the proximate basis of such preference was not known. By conducting behavioral and chemical assays I have determined that Sceliphron caementarium wasps recognize araneids as potential prey due to the presence of chemicals present on their silk and cuticle. By analyzing cuticular extracts of spiders in several families, I have shown that all spiders that are taken by wasps have similar cuticular chemistry; however, all spiders that have that similar chemistry are not taken by iv wasps. Indeed, spiders’ antipredator behavior, morphology and web architecture are important factors that influence prey capture by wasps.

  • Notes on the Behavior of the Kleptoparasitic Spider Argyrodes Elevatus (Theridiidae, Araneae)1
    Revista de Etologia 2012, Vol.11, N°1, 56-67. Notes on the behavior of the kleptoparasitic spider Argyrodes elevatus (Theridiidae, Araneae)1 MARCO CESAR SILVEIRA* & HILTON F. JAPYASSÚ** Butantan Institute Federal University of Bahia Kleptoparasitism is an interaction in which one individual steals captured or processed food from another; spiders of the subfamily Argyrodinae (Theridiidae) may present kleptoparasitic behavior. Aiming to increase the knowledge about this unique strategy, we describe activities accomplished by the kleptoparasitic spider Argyrodes elevatus (Theridiidae) in webs of captive host spiders. After a prey was captured by the host spider, a second prey was offered, so that the kleptoparasite could steal the first prey while the host spider was immobilizing the second one. Using this method, we were able to see a wide range of events, such as the theft of stored preys, the sharing of a prey with the host, the theft of the egg sacs, the predation of host spiders, and others. Finally, we discuss how kleptoparasitism could vary in function of host behavior and how the high behavioral variability of Argyrodes elevatus could be explained. Keywords: kleptoparasitism, behavior, Argyrodes elevatus, Argyrodinae, Theridiidae. Notas sobre o comportamento da aranha cleptoparasita Argyrodes elevatus (Theridiidae, Araneae). O Cleptoparasitismo é um tipo de interação na qual um indivíduo rouba ou furta alimento adquirido por outro; aranhas da subfamília Argyrodinae (Theridiidae) podem apresentar esta estratégia. A fim de ampliar o conhecimento acerca deste curioso comportamento, descrevemos aqui as atividades empenhadas pela aranha cleptoparasita Argyrodes elevatus (Theridiidae) em teias de aranhas hospedeiras, em laboratório. Após a captura de presa por parte da aranha hospedeira, uma segunda presa era oferecida, de maneira que o cleptoparasita pudesse furtar a primeira enquanto a hospedeira capturava a segunda.

  • Estimate of the Daily Catch of Prey by the Wasp Spider Argiope Bruennichi (Scopoli) in the Field: Original Data and Minireview
    Estimate of the daily catch of prey by the wasp spider Argiope bruennichi (Scopoli) in the field: Original data and minireview Martin nyffeler ABSTRACt Contrib. Nat. Hist. 12: 1007–1020. Prey capture by the large orb-weaving spider Argiope bruennichi (Scopoli) (aranei- dae) was investigated in uncut grassland (heavily infested with flowering weeds and shrubs) in the outskirts of Zurich, switzerland, on three consecutive days in early august (between 09:00 and 18:00 hours). A. bruennichi was found to be a predomin- antly diurnal predator of larger-sized grassland insects (Hymenoptera and ortho- ptera composing approx. 90% of the total prey biomass). on average, 38% of the encountered spiders were feeding. it is estimated that adult female A. bruennichi captured, on average, approx. 90 mg (fresh weight) prey web-1 day-1, which is the equivalent of the weight of a worker honey bee. My results were compared with the published estimates of other researchers. Keywords: Wasp spider, Argiope bruennichi, Araneidae, feeding frequency, prey cap- ture rate, uncut grassland, Zurich, Switzerland. introduction In recent years, orb-weaving spiders have become popular model systems to address questions in various fields of biology such as evolutionary biology, ecology, ethology, neurobiology, physiology, and even silk and venom chem- istry (e.g., Craig 1994; Elgar & al. 2000; Herberstein & al. 2005; Blackledge & Hayashi 2006; Schneider & al. 2005, 2006; Blamires & al. 2007, 2008; Brooks & al. 2008; Foellmer 2008), which makes it necessary to keep/breed these spiders under laboratory conditions (Zschokke & Herberstein 2005).
