NEWSLETTER 45 LEICESTERSHIRE September 2011 ENTOMOLOGICAL SOCIETY NEWSLETTER 45 LEICESTERSHIRE September 2011 ENTOMOLOGICAL SOCIETY VC55 Leafhopper reaches Rutland During a moth trapping session on 5 August 2011 at Ketton Working Quarry, in the Grange Top area, two individuals of the large leafhopper Ledra aurita were found (well after midnight). Both individuals were actually inside the traps sitting on the egg boxes. Not at all a typical looking leafhopper - more like a miniature Duck-billed Platypus - with a flattened, slightly concave shovel-like “head”. The pronotum has two large ear-like projections. This curious looking beast is more likely to be found in the deciduous woodlands of south-east England, where it prefers lichen-covered oaks. The Ketton site, on the other hand, is the edge of a working limestone quarry. The actual site is a wide access track with an associated rich limestone grassland flora, albeit alongside a Who’s a pretty boy, then? Two views woodland edge.

One insect group which reacts sensitively to habitat changes are the rove beetles contributing to the maintenance of an undisturbed insect succession during decomposition by mainly hunting fly maggots. However, little is known about carrion-associated rove beetles due to poor taxonomic knowledge. In our study, we unveiled the human-induced and environmental drivers that modify rove beetle communities on vertebrate cadavers. At German forest sites selected by a gradient of management intensity, we contributed to the understanding of the rove beetle-mediated decomposition process. One main result is that an increasing human impact in forests changes rove beetle communities by promoting generalist and more open-habitat species coping with low structural heterogeneity, whereas species like Philonthus decorus get lost.

  • Vidyodaya J., Sci., (1991) Vol
    Vidyodaya J., Sci., (1991) Vol. 3, No.2, pp. 35-43 A PRELIMINARY SURVEY OF DOMICILIARY COCKROACHES AND THEIR OOTHECAL PARASITES IN SRI LANKA N. C. KUMARASINGHE AND JAYANTHI P. EDIRISINGHE Dept. of Zoology, University of Sri Jayewardenepura Nugegoda, Sri Lanka Abstract A survey of domiciliary cockroaches and their oothecal parasites was carried out in 17 districts. The study was based on empty and live cockroach oothecae collected from dwelling houses. Five species of cockroaches; Periplaneta americana (L.) Neostylopyga rhombifolia (Stoll) Periplaneta australasiae (F.) Supella longfpalpa (F.) and Blatella germanica (L.) were found frequenting houses. Of them, P. american a was the most abundant and widely distributed species, while B. germanlca was the least abundant species. P. americana and N. rhombifolia were present in all but one district, while P. australaslae and S. longipalpa were confined to 12 and 08 districts respectively. Mannar district was peculiar in that only one domiciliary species, N. rhombifolia was recorded from there. Only two species of oothecal parasites, Tetrastlchus hagenowli (Ratz.) and Evania appendlgaster (L.) were encountered during the study. Each of these parasite species was characterized by the size of the emergence hole they made in cockroach oothecae. Thus on the basis of the emergence hole alone it was possible to categorize the empty oothecae as being parasitized. Of the oothecae, those of P. americana and P. australiasae were parasitized by both species of parasites, while oothecae of N. rhombifolla was parasitized by T. hagenowii only. Oothecae of S. longipalpa and B. germanica were not parasitii- zed at all. There appears to be a great paucity in the oothecal parasite fauna of Sri Lanka, compared to India where eight species of hymenopterans are known to parasitize oothecae of domiciliary cockroaches.

  • The Diptera of Lancashire and Cheshire: Craneflies and Winter Gnats
    The Diptera of Lancashire and Cheshire: Craneflies and Winter Gnats by Phil Brighton 32, Wadeson Way, Croft, Warrington WA3 7JS [email protected] Version 1.1 26 November 2017 1 Summary This document provides a new checklist for the craneflies and winter gnats (Tipuloidea, Ptychopteridae and Trichoceridae) to extend the lists of the diptera of Lancashire and Cheshire first published by Kidd and Bindle in 1959. Overall statistics on recording activity are given by decade and hectad. Checklists are presented for each of the three Watsonian vice-counties 58, 59, and 60 detailing for each species the number of records, year of earliest and most recent record, and the number of hectads with records. A combined checklist showing distribution by the three vice-counties is also included, covering a total of 264 species, amounting to 75% of the current British checklist. Introduction This report is the third in a series to update and extend the partial checklist of the diptera of Lancashire and Cheshire published in 1959 by Leonard Kidd and Alan Brindle1. There were two previous updates, in 19642 and 19713. The previous reports in this series cover the soldierflies and allies4 and the Sepsidae5, the latter family not having been covered in Ref 1. The reader is referred to the first two reports for the background and rationale of these checklists, as well as the history of diptera recording and available data sources. The description of methodology is also kept to a minimum in the present report: only significant differences from the previous publications will be outlined.

Introduction and Background on Proposed Action This biological assessment (BA) has been prepared by the United States Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS) to evaluate the potential effects on federally-listed threatened and endangered species and designated critical habitat from the movement of baled garbage and regulated (domestic) garbage (GRG) from the State of Hawaii for disposal at landfills in Oregon, Idaho, and Washington. Specifically, garbage is defined as urban (commercial and residential) solid waste from municipalities in Hawaii, excluding incinerator ash and collections of agricultural waste and yard waste. Regulated (domestic) garbage refers to articles generated in Hawaii that are restricted from movement to the continental United States under various quarantine regulations established to prevent the spread of plant pests (including insects, disease, and weeds) into areas where the pests are not prevalent.

  • 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. HOARE, MARIE-CLAUDE LARIVIÈRE, PENELOPE GREENSLADE, ROSA C. HENDERSON, COURTenaY N. SMITHERS, RicarDO L. PALMA, JOHN B. WARD, ROBERT L. C. PILGRIM, DaVID R. TOWNS, IAN McLELLAN, DAVID A. J. TEULON, TERRY R. HITCHINGS, VICTOR F. EASTOP, NICHOLAS A. MARTIN, MURRAY J. FLETCHER, MARLON A. W. STUFKENS, PAMELA J. DALE, Daniel BURCKHARDT, THOMAS R. BUCKLEY, STEVEN A. 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).
