BRUES HARVARD UNIVERSITY ONE afternoonsome twentyyears ago during a winter sojourn in northernFlorida the writer was collectingin- sects in a pine forest given over to the production of turpelntine. Following the usual practice, the bark and sapwood of each tree had been cut away for a distance on one side and a pot hung at the bottomto catch the resin. The scarred trunks of the disfiguredtrees were reeking with oozing resin, and here and there insects of various kinds were imbeddedwhere theyhad been trapped by the sticky exudation. -
Conceptual Design Documentation
Appendix A: Conceptual Design Documentation APPENDIX A Conceptual Design Documentation June 2019 A-1 APPENDIX A: CONCEPTUAL DESIGN DOCUMENTATION The environmental analyses in the NEPA and CEQA documents for the proposed improvements at Oceano County Airport (the Airport) are based on conceptual designs prepared to provide a realistic basis for assessing their environmental consequences. 1. Widen runway from 50 to 60 feet 2. Widen Taxiways A, A-1, A-2, A-3, and A-4 from 20 to 25 feet 3. Relocate segmented circle and wind cone 4. Installation of taxiway edge lighting 5. Installation of hold position signage 6. Installation of a new electrical vault and connections 7. Installation of a pollution control facility (wash rack) CIVIL ENGINEERING CALCULATIONS The purpose of this conceptual design effort is to identify the amount of impervious surface, grading (cut and fill) and drainage implications of the projects identified above. The conceptual design calculations detailed in the following figures indicate that Projects 1 and 2, widening the runways and taxiways would increase the total amount of impervious surface on the Airport by 32,016 square feet, or 0.73 acres; a 6.6 percent increase in the Airport’s impervious surface area. Drainage patterns would remain the same as both the runway and taxiways would continue to sheet flow from their centerlines to the edge of pavement and then into open, grassed areas. The existing drainage system is able to accommodate the modest increase in stormwater runoff that would occur, particularly as soil conditions on the Airport are conducive to infiltration. Figure A-1 shows the locations of the seven projects incorporated in the Proposed Action. -

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. It is also a fewer than 10 Nearctic species (Martin confusing key in that some species key and Papavero 1970, Poole 1996, Scar out at more than one couplet.

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. Key words: biodiversity; blocking primers; DNA detectability half-life; Eriogonum fasciculatum; food webs; intraguild predation; natural enemies.

Pick Your Poison: Molecular Evolution of Venom Proteins in Asilidae (Insecta: Diptera)
toxins Article Pick Your Poison: Molecular Evolution of Venom Proteins in Asilidae (Insecta: Diptera) Chris M. Cohen * , T. Jeffrey Cole and Michael S. Brewer * Howell Science Complex, East Carolina University, 1000 E 5th St., Greenville, NC 27858, USA; [email protected] * Correspondence: [email protected] (C.M.C.); [email protected] (M.S.B.) Received: 5 November 2020; Accepted: 20 November 2020; Published: 24 November 2020 Abstract: Robber flies are an understudied family of venomous, predatory Diptera. With the recent characterization of venom from three asilid species, it is possible, for the first time, to study the molecular evolution of venom genes in this unique lineage. To accomplish this, a novel whole-body transcriptome of Eudioctria media was combined with 10 other publicly available asiloid thoracic or salivary gland transcriptomes to identify putative venom gene families and assess evidence of pervasive positive selection. A total of 348 gene families of sufficient size were analyzed, and 33 of these were predicted to contain venom genes. We recovered 151 families containing homologs to previously described venom proteins, and 40 of these were uniquely gained in Asilidae. Our gene family clustering suggests that many asilidin venom gene families are not natural groupings, as delimited by previous authors, but instead form multiple discrete gene families. Additionally, robber fly venoms have relatively few sites under positive selection, consistent with the hypothesis that the venoms of older lineages are dominated by negative selection acting to maintain toxic function. Keywords: Asilidae; transcriptome; positive selection Key Contribution: Asilidae venoms have relatively few sites under positive selection, consistent with the hypothesis that the venoms of older lineages are dominated by negative selection acting to maintain toxic function. -
ARTHROPODA Subphylum Hexapoda Protura, Springtails, Diplura, and Insects
NINE Phylum ARTHROPODA SUBPHYLUM HEXAPODA Protura, springtails, Diplura, and insects ROD P. MACFARLANE, PETER A. MADDISON, IAN G. ANDREW, JOCELYN A. BERRY, PETER M. JOHNS, ROBERT J. B.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000). -

Box 861161, St. Augustine, Florida 32086, USA, e-mail: [email protected] ABSTRACT Of the approximately 58,000 plus prey records in the Asilidae Predator-Prey Database, 9.1% are Hemiptera (3.5% Heteroptera and 5.6% Homoptera). Forty six of the 133 recognized worldwide Hemiptera families are preyed upon with generally more prey records for female than male robber flies. Potential explanations for robber flies, in particular females, preying upon Hemiptera are discussed. Numbers of Hemiptera prey are examined based on their associated families, genera and species. Hemiptera prey are also discussed in relation to robber fly subfamilies and genera. New records of Hemiptera prey are presented and compared with prey records in the Database. Keywords: Hemiptera, Heteroptera, Homoptera, prey, robber flies, Diptera, Asilidae INTRODUCTION The Hemiptera, the largest order of hemimetabolous insects consisting of approximately 70,000 to 80,000 plus described species (Meyer, 2008), occur worldwide. Traditionally the Hemiptera are divided into two suborders, the Heteroptera and Homoptera, although some taxonomists believe that the Coleorrhyncha, Stenorrhyncha and Auchenorryncha also are suborders. -
