Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity. -

ZooKeys 365: 263–278. doi: 10.3897/zookeys.365.6070 Abstract Empidoidea is one of the largest extant lineages of flies, but phylogenetic relationships among species of this group are poorly investigated and global diversity remains scarcely assessed. In this context, one of the most enigmatic empidoid families is Hybotidae. Within the framework of a pilot study, we barcoded 339 specimens of Old World hybotids belonging to 164 species and 22 genera (plus two Empis as outgroups) and attempted to evaluate whether patterns of intra- and interspecific divergences match the current tax- onomy. -
Hoverfly Newsletter 34
HOVERFLY NUMBER 34 NEWSLETTER AUGUST 2002 ISSN 1358-5029 Long-standing readers of this newsletter may wonder what has happened to the lists of references to recent hoverfly literature that used to appear regularly in these pages. Graham Rotheray compiled these when he was editor and for some time afterwards, and more recently they have been provided by Kenn Watt. For some time Kenn trawled for someone else to take over this task from him, but nobody volunteered. Kenn continued to produce the lists, but now no longer has access to the source that provided him with the references. I therefore now make a plea for someone else to agree to take over this role, ideally producing a list of recent literature for each edition of this newsletter (i.e. twice per year), or if that is not possible, for each alternate edition. Failing a reply to this plea, has anyone any suggestions for a reliable source of references to which I could get access in order to compile the list myself? Copy for Hoverfly Newsletter No. 35 (which is expected to be issued in February 2003) should be sent to me: David Iliff, Green Willows, Station Road, Woodmancote, Cheltenham, Glos, GL52 9HN, Email [email protected], to reach me by 20 December.

The actual arthropod taxa comprising the chick diet are however rarely known, complicating assessments of ecological interactions. In this study, I identified the nestling diet of Svalbard snow bunting (Plectrophenax nivalis) for the first time. Faecal samples of snow bunting chicks were collected in Adventdalen, Svalbard in the breeding season 2018 and analysed via DNA metabarcoding. Simultaneously, the availability of prey arthropods was measured via pitfall trapping. The occurrence of 32 identified prey taxa in the nestling diet changed according to varying abundances and emergence patterns within the tun- dra arthropod community: Snow buntings provisioned their offspring mainly with the most abundant prey items which were in the early season different Chironomidae (Diptera) taxa and Scathophaga furcata (Diptera: Scathophagidae), followed by Spilogona dorsata (Diptera: Mus- cidae). -
Nitrogen Content in Riparian Arthropods Is Most Dependent on Allometry and Order
Wiesenborn: Nitrogen Contents in Riparian Arthropods 71 NITROGEN CONTENT IN RIPARIAN ARTHROPODS IS MOST DEPENDENT ON ALLOMETRY AND ORDER WILLIAM D. WIESENBORN U.S. Bureau of Reclamation, Lower Colorado Regional Office, P.O. Box 61470, Boulder City, NV 89006 ABSTRACT I investigated the contributions of body mass, order, family, and trophic level to nitrogen (N) content in riparian spiders and insects collected near the Colorado River in western Arizona. Most variation (97.2%) in N mass among arthropods was associated with the allometric effects of body mass. Nitrogen mass increased exponentially as body dry-mass increased. Significant variation (20.7%) in N mass adjusted for body mass was explained by arthropod order. Ad- justed N mass was highest in Orthoptera, Hymenoptera, Araneae, and Odonata and lowest in Coleoptera. Classifying arthropods by family compared with order did not explain signifi- cantly more variation (22.1%) in N content. Herbivore, predator, and detritivore trophic-levels across orders explained little variation (4.3%) in N mass adjusted for body mass. Within or- ders, N content differed only among trophic levels of Diptera. Adjusted N mass was highest in predaceous flies, intermediate in detritivorous flies, and lowest in phytophagous flies. Nitro- gen content in riparian spiders and insects is most dependent on allometry and order and least dependent on trophic level. I suggest the effects of allometry and order are due to exoskeleton thickness and composition. Foraging by vertebrate predators, such as insectivorous birds, may be affected by variation in N content among riparian arthropods. Key Words: nutrients, spiders, insects, trophic level, exoskeleton, cuticle RESUMEN Se investiguo las contribuciones de la masa de cuerpo, orden, familia y el nivel trófico al con- tenido de nitógeno (N) en arañas e insectos riparianos (que viven en la orilla del rio u otro cuerpo de agua) recolectadaos cerca del Rio Colorado en el oeste del estado de Arizona. -

A review of the Archiceroptera Papp genus complex (Diptera: Sphaeroceridae: Limosininae) by Steven Mark Paiero A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Environmental Sciences Guelph, Ontario, Canada © Steven Mark Paiero, December, 2017 ABSTRACT: A review of the Archiceroptera Papp genus complex (Diptera: Sphaeroceridae: Limosininae) Steven Mark Paiero Advisor: University of Guelph, 2017 Dr. S.A. Marshall This thesis has two parts. The first part investigates the relationships between the Archiceroptera genus complex and other members of the Limosininae (Diptera: Sphaeroceridae). A focus is placed on the relationships within the larger epandrial process group, which contains Bitheca, Bromeloecia, Pterogramma, Aptilotella, and Robustagramma, along with Archiceroptera, Rudolfina and several previously unplaced species groups. Molecular and morphological data sets provide the first phylogeny of the group, and were used to support the inclusion of several unplaced species groups within Rudolfina and Archiceroptera, while one new genus is described. Pectinosina gen. nov. includes two species: P. prominens (Duda), previously placed in Rudolfina, and P. carro n. sp. The second part of the thesis deals with revisions of Archiceroptera Papp and Rudolfina Roháček. Rudolfina now includes 13 described species, nine of which are newly described here (R. bucki, R. exuberata, R. howdeni, R. megepandria, R. pauca, R. pilosa, R. newtoni, R. remiforma, and R. tumida). Archiceroptera now includes 29 species, of which 27 are newly described here (A. adamas, A. addenda, A. barberi, A. basilia, A. bilobata, A. bisetosus, A. braziliensis, A. brevivilla, A. browni, A. caliga, A. calligraphia, A. cobolorum, A. -

BARNES The Arthropod Museum, Department of Entomology, University of Arkansas, Fayetteville, AR 72701-1201, U.S.A. (e-mail: [email protected]) Abstract.-Atomosia arkansensis, new species, is described from specimens collected in blackland prairie in southern Arkansas, and Atomosia tibialis is reported the first time from North America north of Mexico. A new key to Nearctic Atomosia species is presented. Atomosia melanopogon and A. mucida are noted to be sexually dimorphic. In addition to more standard characters, the open or closed condition of cell r5 and the length of the pedicel and flagellum relative to the length of the scape are· used to distinguish similar species. Lectotypes are designated for Atomosia mucida, Atomosia puella, and Atomosia sayii. Atomosia echemon is synonymized with A. puella (new synonymy), and A. mucidoides is synonymized with A. sayii (new synonymy). Key Words: Diptera, Brachycera, robber fly, Asilidae, Atomosia, Nearctic The New World genus Atomosia Mac for species identification and does not quart consists of small, robust robber utilize some highly diagnostic morpho flies with elongate, slender antennae and logical characters, such as the relative a punctulate abdomen. It comprises sizes of the antennomeres and the more than 50 Neotropical species and condition of wing cell r5.

Gut Content Metabarcoding Unveils the Diet of a Flower‐Associated Coastal
ECOSPHERE NATURALIST No guts, no glory: Gut content metabarcoding unveils the diet of a flower-associated coastal sage scrub predator PAUL MASONICK , MADISON HERNANDEZ, AND CHRISTIANE WEIRAUCH Department of Entomology, University of California, Riverside, 900 University Avenue, Riverside, California 92521 USA Citation: Masonick, P., M. Hernandez, and C. Weirauch. 2019. No guts, no glory: Gut content metabarcoding unveils the diet of a flower-associated coastal sage scrub predator. Ecosphere 10(5):e02712. 10.1002/ecs2.2712 Abstract. Invertebrate generalist predators are ubiquitous and play a major role in food-web dynamics. Molecular gut content analysis (MGCA) has become a popular means to assess prey ranges and specificity of cryptic arthropods in the absence of direct observation. While this approach has been widely used to study predation on economically important taxa (i.e., pests) in agroecosystems, it is less frequently used to study the broader trophic interactions involving generalist predators in natural communities such as the diverse and threatened coastal sage scrub communities of Southern California. Here, we employ DNA metabarcoding-based MGCA and survey the taxonomically and ecologically diverse prey range of Phymata pacifica Evans, a generalist flower-associated ambush bug (Hemiptera: Reduviidae). We detected predation on a wide array of taxa including beneficial pollinators, potential pests, and other predatory arthropods. The success of this study demonstrates the utility of MGCA in natural ecosystems and can serve as a model for future diet investigations into other cryptic and underrepresented communities.
