    Pacific Insects 5 (4) : 837-847 December 30, 1963 ANISODACTYLUS BINOTATUS FABR., A CARABID BEETLE NEW TO NEW ZEALAND, AND A REVIEW OF THE EXOTIC CARABID FAUNA By R. L. C. Pilgrim DEPT, OF ZOOLOGY, UNIVERSITY OF CANTERBURY, NEW ZEALAND Abstract: Anisodactylus binotatus Fabr. 1787 (Col.: Carabidae), an introduced species now established in Canterbury (South Island), New Zealand, is reported for the first time. The literature respecting other carabids sometimes recorded as introduced is reviewed; Ago- nochila binotata (White, 1846), Agonum submetallicum (White, 1846), Hypharpax australasiae (Dejean, 1829) and Pentagonica vittipennis Chaudoir, 1877 are shown to be better considered as endemic to the Australia - New Zealand area. Other species are classed as either native to New Zealand, clearly introduced though not all established, or of doubtful occurrence in New Zealand. Introduction: The Carabidae of New Zealand are predominantly endemic species, but a small number of exotic species has been recorded. This paper reports a further introduc­ tion to the carabid fauna of this country and concludes with a survey of recorded exotic Carabidae in New Zealand. Specimens of the newly-recorded species were collected in domestic gardens in Christ­ church, and were included in a collection sent for identification to Dr. E. B. Britton, British Museum (Nat. Hist.), who kindly drew the writer's attention to the fact that they were so far unreported from New Zealand. Description of adult (from New Zealand specimens) Fig. 1.

ZooKeys 100: 517–532. doi: 10.3897/ zookeys.100.1543 Abstract This paper summarizes the current knowledge on winter active Carabidae in Central and Northern Eu- rope. In total 73 winter active species are listed, based on literature and own observations. Ground beetles are among the three most numerous Coleoptera families active during the autumn to spring period. The winter community of Carabidae is composed both of larvae (mainly autumn breeding species) and adults, as well as of epigeic species and those inhabiting tree trunks. Supranivean fauna is characterized by lower species diversity than the subnivean fauna. The activity of ground beetles decreases in late autumn, is lowest during mid-winter and increases in early spring.

Yanahan University of Illinois at Urbana-Champaign During the Pleistocene, glacial advances left a small gap in the northwestern corner of Illinois, southwestern Wisconsin, and northeastern Iowa, which were never covered by the advancing Pleistocene glaciers (Taylor et al. 2009, p. 8, fig. 2.2). This is the Driftless Area – and it is one of Illinois’ most unique natural regions, comprising little more than 1% of the state. Illinois’ Driftless Area harbors more than 30 threatened or endangered plant species, and several unique habitat types. Among these habitats are talus, or scree, slopes, some of which retain ice throughout the year. The talus slopes that retain ice through the summer, and thus form a habitat which rarely exceeds 50 °F, even when the surrounding air temperature is in the 90’s °F, are known as “algific slopes.” While there are numerous examples of algific slopes in Iowa and Wisconsin, this habitat is very rare in Illinois (fewer than ten truly algific sites are known in the state).

    From Characters of the Female Reproductive Tract

    Phylogeny and Classification of Caraboidea Mus. reg. Sci. nat. Torino, 1998: XX LCE. (1996, Firenze, Italy) 107-170 James K. LIEBHERR and Kipling W. WILL* Inferring phylogenetic relationships within Carabidae (Insecta, Coleoptera) from characters of the female reproductive tract ABSTRACT Characters of the female reproductive tract, ovipositor, and abdomen are analyzed using cladi­ stic parsimony for a comprehensive representation of carabid beetle tribes. The resulting cladogram is rooted at the family Trachypachidae. No characters of the female reproductive tract define the Carabidae as monophyletic. The Carabidac exhibit a fundamental dichotomy, with the isochaete tri­ bes Metriini and Paussini forming the adelphotaxon to the Anisochaeta, which includes Gehringiini and Rhysodini, along with the other groups considered member taxa in Jeannel's classification. Monophyly of Isochaeta is supported by the groundplan presence of a securiform helminthoid scle­ rite at the spermathecal base, and a rod-like, elongate laterotergite IX leading to the explosion cham­ ber of the pygidial defense glands. Monophyly of the Anisochaeta is supported by the derived divi­ sion of gonocoxa IX into a basal and apical portion. Within Anisochaeta, the evolution of a secon­ dary spermatheca-2, and loss ofthe primary spermathcca-I has occurred in one lineage including the Gehringiini, Notiokasiini, Elaphrini, Nebriini, Opisthiini, Notiophilini, and Omophronini. This evo­ lutionary replacement is demonstrated by the possession of both spermatheca-like structures in Gehringia olympica Darlington and Omophron variegatum (Olivier). The adelphotaxon to this sper­ matheca-2 clade comprises a basal rhysodine grade consisting of Clivinini, Promecognathini, Amarotypini, Apotomini, Melaenini, Cymbionotini, and Rhysodini. The Rhysodini and Clivinini both exhibit a highly modified laterotergite IX; long and thin, with or without a clavate lateral region.

    Consequences of Omnivory and Alternative Food Resources on the Strength of Trophic Cascades

    ABSTRACT Title of Dissertation: CONSEQUENCES OF OMNIVORY AND ALTERNATIVE FOOD RESOURCES ON THE STRENGTH OF TROPHIC CASCADES Steven D. Frank, Doctor of Philosophy, 2007 Directed By: Associate Professor Paula M. Shrewsbury Department of Entomology & Professor Robert F. Denno Department of Entomology Omnivorous predators that feed on prey and plant resources are recognized as an important component of food webs but their impact on herbivore populations and trophic dynamics is unpredictable. Feeding on food items from multiple trophic levels increases the reticulate nature of food webs and the labile role of omnivores in promoting trophic cascades. Using carabid beetles in a corn agroecosystem, this research explored the interactive effects of predator guild (omnivore or carnivore) and the trophic origin of alternative food resources (seeds or fly pupae) on the control of herbivores (black cutworms) and plant survival. I demonstrated that the trophic guild and feeding performance of carabids can be predicted from their mandibular morphology. Carnivorous carabids, using mandibles with sharp points and a long shearing edge, kill and consume caterpillars more efficiently than omnivores that have mandibles with wide molar areas adapted for consuming prey and seeds. Omnivore preference for seeds and pupae further reduced their consumption of cutworms, which resulted in increased plant damage, ultimately dampening trophic cascades. In open field plots the abundance of omnivorous carabids and ants increased in response to seed but not pupae whereas neither subsidy affected the abundance of carnivorous predators. Pupae subsidies reduced predation of cutworms by carnivores and omnivores, consequently reducing seedling survival. However, in seed subsidized plots omnivorous predators switched from seeds to higher quality cutworm prey.

    Coleoptera: Carabidae) Diversity

    VEGETATIVE COMMUNITIES AS INDICATORS OF GROUND BEETLE (COLEOPTERA: CARABIDAE) DIVERSITY BY ALAN D. YANAHAN THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology in the Graduate College of the University of Illinois at Urbana-Champaign, 2013 Urbana, Illinois Master’s Committee: Dr. Steven J. Taylor, Chair, Director of Research Adjunct Assistant Professor Sam W. Heads Associate Professor Andrew V. Suarez ABSTRACT Formally assessing biodiversity can be a daunting if not impossible task. Subsequently, specific taxa are often chosen as indicators of patterns of diversity as a whole. Mapping the locations of indicator taxa can inform conservation planning by identifying land units for management strategies. For this approach to be successful, though, land units must be effective spatial representations of the species assemblages present on the landscape. In this study, I determined whether land units classified by vegetative communities predicted the community structure of a diverse group of invertebrates—the ground beetles (Coleoptera: Carabidae). Specifically, that (1) land units of the same classification contained similar carabid species assemblages and that (2) differences in species structure were correlated with variation in land unit characteristics, including canopy and ground cover, vegetation structure, tree density, leaf litter depth, and soil moisture. The study site, the Braidwood Dunes and Savanna Nature Preserve in Will County, Illinois is a mosaic of differing land units. Beetles were sampled continuously via pitfall trapping across an entire active season from 2011–2012. Land unit characteristics were measured in July 2012. Nonmetric multidimensional scaling (NMDS) ordinated the land units by their carabid assemblages into five ecologically meaningful clusters: disturbed, marsh, prairie, restoration, and savanna.

Carabids, Amara aenea, larval diet, life histories, seed predation Abstract. The duration of development, survivorship and adult size were compared for the larvae of Amara aenea reared in the first generation on pure diets of seeds ( Stellaria media, Capsella bursa-pastoris, Tussilago farfara, Plantago major, Urtica or dioica, Potentilla argentela), or a pure diet of yellow mealworms (Tenebrio molitor larvae), and on a mixed diet of seeds and mealworm larvae (T. molitor, S. media and C. bursa-pastoris). To ascertain any long-term effects of pure diets, the beetles were reared on the same pure diet for several generations, or on different pure diets in different generations. The hypothesis that the larvae are primary omnivorous was tested. The evidence that the larvae of A. aenea are primary omnivorous was obtained by revealing that the larvae reared on the mixed diet of insects and seeds survived better, and developed faster in larger adults than those reared on the pure diets of seeds or insects. When the beetles were reared on the same pure diet for several generations, survivorship, and in most cases also the duration of development, did not change. However, when the beetles were reared on a different pure diet each generation, survi­ vorship significantly decreased in successive generations. INTRODUCTION Recently, an investigation of nine closely related The adults of the genus Amara Bonelli (Coleoptera: Amara species suggested that their larvae can be divided Carabidae) are generally considered granivorous, since into granivorous, omnivorous and insectivorous forms many have been observed feeding on flower heads or (Saska & Jarošík, 2001).

State Street, West Lafayette, Indiana 47907-2089, USA, ‡USDA-ARS, Invasive Insect Biocontrol and Behavior Laboratory, BARC-West, Beltsville, Maryland 20705, USA Abstract The soybean aphid, Aphis glycines (Hemiptera: Aphididae), is a pest of soybeans in Asia, and in recent years has caused extensive damage to soybeans in North America. Within these agroecosystems, generalist predators form an important component of the assemblage of natural enemies, and can exert significant pressure on prey populations. These food webs are complex and molecular gut-content analyses offer nondisruptive approaches for exam- ining trophic linkages in the field. We describe the development of a molecular detection system to examine the feeding behaviour of Orius insidiosus (Hemiptera: Anthocoridae) upon soybean aphids, an alternative prey item, Neohydatothrips variabilis (Thysanoptera: Thripidae), and an intraguild prey species, Harmonia axyridis (Coleoptera: Coccinellidae). Specific primer pairs were designed to target prey and were used to examine key trophic connections within this soybean food web. In total, 32% of O. insidiosus were found to have preyed upon A. glycines, but disproportionately high consumption occurred early in the season, when aphid densities were low.
