Invertebrate Species Recorded at Charity Fields on 24 April and 22 June 2019 - by Kate Nightingale Invertebrate species recorded at Charity Fields on 24 April and 22 June 2019 - by Kate Nightingale Insect Type (Order) Local Common Name Scientific Name Notes There are three similar Sialis species in Britain. They have no Alder fly (Megaloptera) Alder Fly ‘Sialis’ species association with Alder trees other than being found on foliage beside ponds and streams. Found in a wide range of habitats. The earliest of the ‘carder’ Bee (Hymenoptera) Common Carder Bee Bombus pascuorum bees to emerge in spring. Queens are distinctive but workers are difficult to distinguish Bee (Hymenoptera) Buff-tailed Bumblebee Bombus terrestris from some other bee species. Nests in holes, including existing cavities in dead wood, plant Bee (Hymenoptera) Blue Mason Bee Osmia caerulescens stems and masonry. Occasional in Leicestershire & Rutland, being more common in southern counties. Hibernates during winter in cracks and crevices, sometimes in Beetle (Coleoptera) 7 Spot Ladybird Coccinella septempunctata large numbers. They often migrate here from the Continent in warm years. Visits flowers. The male has bulging rear femurs and both Beetle (Coleoptera) Swollen-thighed Beetle Oedemera nobilis sexes are iridescent green with gaping wing-cases (elytra). A small, long and slender ‘flower beetle’, with grey or sage Beetle (Coleoptera) [no common name] Oedemera lurida green wing casings. Invasive alien species arrived in the UK in 2004 and now well established. Various colour and pattern-forms mimic our Beetle (Coleoptera) Harlequin Ladybird Harmonia axyridis native ladybirds. Eats the eggs and larvae of butterflies, moths, and other ladybirds. A small inconspicuous-looking weevil. The larval food plants Beetle (Coleoptera) Broad Bean Weevil Bruchus rufimanus are members of the vetch family (Vicia). Fairly frequent in Leicestershire & Rutland. Found in hay meadows and damper grassland areas. The Beetle (Coleoptera) [no common name] Cantharis nigra black wing-casings are shiny with a layer of fine hairs. Fairly frequent in Leicestershire & Rutland. 1 Invertebrate species recorded at Charity Fields on 24 April and 22 June 2019 - by Kate Nightingale Found on nettles, and favours damp woodland. Uncommon Bug (Hemiptera) [no common name] Calocoris alpestris in Leicestershire & Rutland; mainly found in upland or northern areas (including hills in southern England). Prefers damper habitats and feeds on grasses. Males change Bug (Hemiptera) [no common name] Leptopterna dolabrata colour as they age, from black and yellow to black and orange-red. A large mottled-brown bug with a broad abdomen. Can Bug (Hemiptera) Dock Bug Coreus marginatus sometimes be seen feeding in large numbers prior to hibernation. Larvae feed on Dock and other related plants. Males are white with orange wing tips; females are white Butterfly (Lepidoptera) Orange Tip Anthocharis cardamines with black wing tips so may be confused with other species. Both have mottled green underwings. Prefers damp habitats. Can be found in any grassy habitat, sometimes in large Butterfly (Lepidoptera) Meadow Brown Maniola jurtina numbers. Variable colour forms exist, but are distinguishable from the Gatekeeper by its single 'eye spot’. Prefers tall and uncut grassy areas. Dark checkered markings Butterfly (Lepidoptera) Large Skipper Ochlodes sylvanus on the lower part of the wings helps distinguish from other 'skippers' which can sometimes be the same size. Adults hibernate through cold weather and may be seen Butterfly (Lepidoptera) Brimstone Gonepteryx rhamni flying on warm days throughout the year. Unlike some other species they are never seen in large numbers. Found in woodland and anywhere with sufficient scrub to Butterfly (Lepidoptera) Speckled Wood Pararge aegeria provide shaded conditions. Larval food plants are grasses. The male is blue with a dark wing band; the female is Damselfly (Odonata) Banded Demoiselle Calopteryx splendens green/gold with no band. It is very sensitive to pollution and its presence indicates clean water. Mature females can be blue, brown or greenish. Males can Damselfly (Odonata) Common Blue Damselfly Enallagma cyathigerum be a drab lilac colour when newly emerged before becoming blue after a few days. 2 Invertebrate species recorded at Charity Fields on 24 April and 22 June 2019 - by Kate Nightingale A spur on the side of the thorax distinguishes it from the Damselfly (Odonata) Azure Damselfly Coenagrion puella Common Blue damselfly. Prefers well-vegetated, sheltered habits near water, but also hedgerows and woodland rides. A jet -black fly with orange-gold on its face, feet and wing- Fly (Diptera) Noon Fly Mesembrina meridiana base. Breeds in dung. Large flies with a chequered grey and white abdomen and Fly (Diptera) Flesh Fly ‘Sarcophaga' species large red eyes. Many species can only be identified by microscopic examination. Larvae feed on decaying meat. Two of the three Syrphus species are common, the other less Hoverfly (Diptera) ‘Syrphus’ species so. Detailed examination of a specimen is the only way to distinguish between the species. The two 'moustache' black bands the abdomens are unique Hoverfly (Diptera) Marmalade Hoverfly Episyrphus balteatus among hoverflies. Can be seen all year. Hibernates in winter and emerges on warmer days. An excellent bumblebee mimic, there are two main varieties Hoverfly (Diptera) [no common name] Volucella bombylans which mimic different species of bumblebee; one with an orange-red ‘tail’ and the other with a white ‘tail’. The variable orange markings on the abdomen are shared by Hoverfly (Diptera) Tapered Drone Fly Eristalis pertinax other species but the pale front feet and the shape of the hind femur are key to identification. One of Britain’s largest flies. It has a pale cream band across Hoverfly (Diptera) Pellucid Fly Volucella pellucens its abdomen and large dark spots on the wings. Seen in scrubby areas, hedgerows and on umbellifers. Small yellow and pale brown moth found in various habitats. Moth (Lepidoptera) Common Yellow Conch Agapeta hamana The Larval food plant is thistle. It is mainly nocturnal but can be disturbed from its resting place during the day. Small moth with vary variable forms and patterns, although a Moth (Lepidoptera) Common Marble Celypha lacunana strong indentation along the length of the forewing is one distinguishing feature. 3 Invertebrate species recorded at Charity Fields on 24 April and 22 June 2019 - by Kate Nightingale A very variable species, ranging from bright yellow to dark Moth (Lepidoptera) Yellow Shell Camptogramma bilineata brown, and also variable in size. Prefers damper habitats. One of the commonest 'grass moths'. It has one or two Moth (Lepidoptera) Garden Grass-veneer Chrysoteuchia culmella angled cross-lines and metallic golden fringe to the forewings. Rests head-down on grass stalks. Plain-looking and buff-coloured, with yellowish colouring Moth (Lepidoptera) Timothy Tortrix Aphelia paleana around the head and base of the forewings. Prefers waste ground and damp areas. Feeds on various herbaceous plants. Not easily confused with any other British moth species. The Moth (Lepidoptera) Cinnabar Tyria jacobaeae yellow and black banded larvae feed voraciously on ragwort and related plants. Varying colour forms from pale creamy grey to dark reddish Moth (Lepidoptera) Middle-barred Minor Oligia fasciuncula brown, with a central band across the forewings. Favours damp areas and often seen on umbellifers. Both sexes have a shiny green thorax; the female has a broad Soldierfly (Diptera) Broad Centurion Chloromyia formosa blue-green abdomen and the male’s is bronze. Larvae feed on decaying matter and adults take nectar from flowers. The upright position of the abdomen in flight helps identify this species. Females visit the nests of solitary bees or wasps Wasp (Hymenoptera) [no common name] Gasteruption jaculator and deposit her own eggs near to those of the host. Occasional in Leicestershire & Rutland. 4 Invertebrate species recorded at Charity Fields on 24 April and 22 June 2019 - by Kate Nightingale .

  • Bees and Wasps of the East Sussex South Downs
    A SURVEY OF THE BEES AND WASPS OF FIFTEEN CHALK GRASSLAND AND CHALK HEATH SITES WITHIN THE EAST SUSSEX SOUTH DOWNS Steven Falk, 2011 A SURVEY OF THE BEES AND WASPS OF FIFTEEN CHALK GRASSLAND AND CHALK HEATH SITES WITHIN THE EAST SUSSEX SOUTH DOWNS Steven Falk, 2011 Abstract For six years between 2003 and 2008, over 100 site visits were made to fifteen chalk grassland and chalk heath sites within the South Downs of Vice-county 14 (East Sussex). This produced a list of 227 bee and wasp species and revealed the comparative frequency of different species, the comparative richness of different sites and provided a basic insight into how many of the species interact with the South Downs at a site and landscape level. The study revealed that, in addition to the character of the semi-natural grasslands present, the bee and wasp fauna is also influenced by the more intensively-managed agricultural landscapes of the Downs, with many species taking advantage of blossoming hedge shrubs, flowery fallow fields, flowery arable field margins, flowering crops such as Rape, plus plants such as buttercups, thistles and dandelions within relatively improved pasture. Some very rare species were encountered, notably the bee Halictus eurygnathus Blüthgen which had not been seen in Britain since 1946. This was eventually recorded at seven sites and was associated with an abundance of Greater Knapweed. The very rare bees Anthophora retusa (Linnaeus) and Andrena niveata Friese were also observed foraging on several dates during their flight periods, providing a better insight into their ecology and conservation requirements.

A total of 1272 two-winged species that belong to 58 families has been reported from theVitosha Mt. The Tachinidae (208 species or 16.3%) and Cecidomyiidae (138 species or 10.8%) are the most numerous. The greatest number of species has been found in the mesophylic and xeromesophylic mixed forests belt (707 species or 55.6%) and in the northern part of the mountain (645 species or 50.7%). The established species belong to 83 areographical categories. The dipterous fauna can be divided into two main groups: 1) species with Mediterranean type of distribution (53 species or 4.2%) – more thermophilic and distributed mainly in the southern parts of the Palaearctic; seven species of southern type, distributed in the Palaearctic and beyond it, can be formally related to this group as well; 2) species with Palaearctic and Eurosiberian type of distribution (1219 species or 95.8%) – more cold-resistant and widely distributed in the Palaearctic; 247 species of northern type, distributed in the Palaearctic and beyond it, can be formally related to this group as well. The endemic species are 15 (1.2%). The distribution of the species according to the zoogeographical categories in the vegetation belts and the distribution of the zoogeographical categories in each belt are considered. The dipteran fauna of the Vitosha Mt. is compared to this of the Rila and Pirin Mountains.

  • How Habitat Influences Native Pollinators in Intensive Agricultural Landscapes
    Small Restoration, Big Impacts: How Habitat Influences Native Pollinators in Intensive Agricultural Landscapes by Caitlin Paterson A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Integrative Biology Guelph, Ontario, Canada © Caitlin Paterson, October, 2014 ABSTRACT SMALL RESTORATION, BIG IMPACTS: HOW HABITAT INFLUENCES NATIVE POLLINATORS IN INTENSIVE AGRICULTURAL LANDSCAPES Caitlin Paterson Advisor: University of Guelph, 2014 Professor A.S. MacDougall This study examined the impact of small-scale restoration of tallgrass prairie on native bee community composition on farms in Southern Ontario, Canada. Three farms with various crops (corn (Zea), Saskatoon berries (Amelanchier alnifolia), squash, pumpkin, zucchini, melon (Curcurbitaceae), soybeans (Glycine), and green beans (Phaseolus)) were surveyed in the summer of 2013. Availability of nesting and foraging habitat for bees was estimated and a combination of pan-trapping and sweep netting was used to capture specimens on 40 plots per farm. Results were analysed using ordination-based techniques in R, and indicated that prairie provides a diverse floral resource on which a complex and abundant array of bees forage. Restored habitat accounted for 33% of the total richness and 72% of the total abundance of native bees. This demonstrates that even small-scale restoration (~10% of each farm) may have an impact on the ability of farms in southern Ontario to support native bees. ACKNOWLEDGMENTS Firstly, thank you to my advisor Andrew MacDougall and the rest of the MacDougall lab for their assistance and guidance with this project for the past two years. I would like to thank the lab/field technicians who assisted me in conducting my field work and identifying and sorting through specimens: Cara Bulger, April Clyburne-Sherin, and Felicia Syer.

    J. Entomol. Res. Soc., 16(2): 23-27, 2014 ISSN:1302-0250 A New Record for the Turkish House Fly Fauna: Mesembrina meridiana (L. 1758) (Diptera: Muscidae) Cenk ONSOY Ferhat ALTUNSOY Furkan Halil AKAY Anadolu University, Faculty of Science, Department of Biology 26470 Eskişehir, TURKEY e-mail: [email protected] ABSTRACT Muscidae is a wide spread calyptrate family all over the World. On the other hand this family has great importance for ecological, veterinary, medical and forensic science. This family presented with 578 species in Europe and also has great species richness in Turkey. In this study Mesembrina meridiana (L. 1758) was reported first time in Turkey. We expect thatM. meridiana also have great forensic importance due to the two specimens were collected on 3th and 8th days of decomposition; fresh and bloat stages when the Calliphoridae and Sarcophagidae species not certainly active due to seasonal activity periods. Key words: Mesembrina meridiana, new record, Turkish Muscidae fauna, house fly. INTRODUCTION The Muscidae is a large and cosmopolitan family of Diptera that belong to the Calyptrata family group. Today Diptera are one of the three largest and most diverse animal groups in the world comprised of over 160,000 named species in about 150 families (Ssymank et al., 2008). In the Catalogue of Palaearctic Diptera (Pont, 1986), 835 valid species are listed, but in recent years many new species have been described especially from the eastern Palaearctic, so far in Europe 578 species reported (Pont, 2004; Pont, 2005; Gregor and Rozkošný, 2007; Pont and Grach, 2008; Pont and Gregor, 2008; Gregor and Rozkošný, 2009; Moon, 2002).
