SUMMARY:Grimsargh Wetlands Invertebrate Recording Day
DESCRIPTION:Book here. \nGrimsargh Wetlands comprises three decommissioned former reservoirs and surrounding land managed by a dedicated Trust near Preston in Lancashire. There is variety of grassland habitats surrounding the former reservoirs\, from species-rich free draining south-facing embankments through to tall\, damp vegetation on heavy soils. One of the water bodies is shallow enough to virtually dry up in summer\, revealing good access to reedbed habitat. The third former reservoir has become a fen habitat dominated willow scrub and more accessible reedbed. The site is largely closed to the public and even volunteer work parties do not access large areas between April and July for the bird breeding season. The site managers are not aware of any attempts to record invertebrates apart from spiders. Our visit represents a special opportunity to access this reserve. \nNearest Train Station: Preston \nNearest Bus Stops: Catch the No.1 bus service Preston to Longridge from stand 29 at Preston Bus Station. Leave the bus at The Plough\, Sunnybank or Elston Lane stops on Preston Road. Travelling from Longridge\, leave the bus at Elston Lane or the Village Hall. \nPlease be aware that whilst we welcome invertebrate recorders of all experience levels\, our recording days are not taught or guided sessions. (Check out our webinars/workshops here). \nEvents will be subject to cancellation if there is severe weather forecast. \nBooking essential: Further details regarding meeting place etc. will be circulated before the day.

SUMMARY:Crag Bank Invertebrate Recording Day Visit 2
DESCRIPTION:Book here. \nCrag Bank Nature Reserve is 3.7 ha.

SUMMARY:Errwood & Fernilee Reservoirs Invertebrate Recording Day
DESCRIPTION:Book here \nJoin us for a joint recording day with Sorby Invertebrate Group and Cheshire Bee Group at Errwood and Fernilee Reservoirs in the Goyt Valley area. The site consists of mostly acid grassland/moorland with a mosaic of broadleaved woodland and gullies. \nPlease note there are no toilets on site. \nParking: at The Street Car Park. \nPlease be aware that whilst we welcome invertebrate recorders of all experience levels\, our recording days are not taught or guided sessions. (Check out our webinars/workshops here). \nEvents will be subject to cancellation if there is severe weather forecast. \nBooking essential: Further details regarding meeting place etc. will be circulated before the day.

SUMMARY:Chalcid wasps (Chalcidoidea) Workshop
DESCRIPTION:Book here. \nThis one-day workshop with Steve Compton will cover the identification of chalcid wasps\, one of the most species-rich groups of insects in the UK. An introductory lecture will outline the ecology and anatomy of these often very small but beautifully-metallic wasps. \nThe higher classification of chalcids has changed in recent years\, with a considerable expansion in the number of recognised families within the world fauna. By the end of the day\, participants should be able to distinguish between the families present in Britain. \nOur tutor: Steve Compton is the retired Reader in Entomology at the University of Leeds and a Fellow of the Royal Entomological Society. He has an interest in parasitic hymenopterans in general\, but his research has centred on one particular group of chalcids – the fig wasps responsible for pollination of fig trees. His research has taken him to a many different countries and habits – from the rainforests of Borneo to investigate how high chalcids fly\, to the Namib Desert where he showed that some wasps can travel hundreds of kilometres between their hosts. \nWorkshop level – Intermediate

SUMMARY:Picture-winged Flies Workshop
DESCRIPTION:Book here. \nThis two-day workshop with David Clements will cover the identification and biology of flies in the families Tephritidae\, Ulidiidae\, Platystomatidae\, Pallopteridae and Opomyzidae – the main families of the so-called ‘picture-winged flies’.  The programme will start with a general introduction to the acalyptrate Diptera families and the distinguishing of the target families\, followed by a detailed summary of the species\, ecology and biology\, main identification resources and techniques for collection\, preservation\, identification and recording etc.  The latter will include a demonstration of genitalia preparation – a key identification technique which many beginners find a bit intimidating.  A revised and updated set of unpublished keys will be provided\, together with access to specimens from the museum’s collection.  Participants can also bring along their own material for identification. \nDavid Clements is a Fellow of the Royal Entomological Society and runs the national Picture-winged Flies Recording Scheme\, as well as the Conopid Recording Scheme and many other involvements.  Until recently he ran an ecological consultancy business and was previously an entomologist working at the National Trust Biological Survey and at the National Museum of Wales.  He is now retired and is currently involved in researching the entomology of the UK Overseas Territories\, with interests in a wide range of invertebrates. \nWorkshop level – Beginner/Intermediate  \nPhoto: Tephritis formosa (female) by Alvesgaspar\, CC BY‑SA 3.0\, via Wikimedia Commons

SUMMARY:Introduction to ‘Proctos’ Parasitoid Wasps Workshop
DESCRIPTION:Book here \nIntroduction to ‘Proctos’: Parasitoid wasps of the superfamilies Diaprioidea\, Platygastroidea\, Proctotrupoidea and Ceraphronoidea  \nSmall parasitoid wasps are among the most diverse and numerous insects in terrestrial ecosystems where they exploit other insects and spiders as food for their young.  \nThis one-day workshop will be a practical based introduction to parasitoid wasps of the superfamilies Diaprioidea\, Platygastroidea\, Proctotrupoidea and Ceraphronoidea. Participants will develop an understanding of collection\, preservation\, and study techniques\, learn to identify families and subfamilies\, and become familiar with key resources for further learning. \nMaterial from the museum’s collection will be available for study and participants are encouraged to bring their own specimens.  \nOur tutor David Notton is an expert in diapriid wasps and was formerly Senior Curator of Hymenoptera at the Natural History Museum London.  \nWorkshop level – Intermediate
