title: Louse flies (Diptera: Hippoboscidae): United Kingdom, Republic of Ireland and Isle of Man: Citizen science data: Part 1, mapping

description: British for Ornithomology licensed bird Ringers, and other citizen
 scientists with an interest in entomology, collected over 3500 louse flies
 and keds (Diptera: Hippoboscidae) for the Mapping the UK's Flat Flies
 Project. The original project expanded to include the Republic of Ireland
 and Isle of Man as well as the United Kingdom, and includes a few flies
 from as early as 2002 as well as those from the main study period of 2020
 - 2024. The flies species included in this datadase are the UK
 Hippoboscids: louse flies: Crataerina pallida, Ornthomya
 avicularia, Ornithomya chloropus, Ornithomya fringillina, Ornithomya
 biloba, Steneteryx hirundinis,  Pseudolynchia garzettae and
 Icosta minor, and the keds Lipoptena cervi, Hippobosca equina and
 Melophagus ovinus. This dataset includes the species names, dates of
 collection (or adult emergence if flies were collected as puparia), and
 location details to an accuracy of a 1 km grid square for most UK records
 and 10 km for the records from the Repubic of Ireland. All host data has
 been removed to protect the locations of protected and other rare species
 of birds.
description: This dataset contains some of the raw data from the "Mapping
 the UK's Flat Flies Project", including the dates flies were
 caught and their location. It includes data on louse flies and keds
 collected from the United Kingdom, Republic of Ireland and Isle of Man, by
 British Trust for Ornithology (BTO) licensed bird ringers and other
 citizen scientists with an interest in entomolgy. Most records are from
 the main study period June 2020 to May 2024, but there are a few earlier
 records dating back to 2002. Volunteer BTO bird ringers
 were sent collection kits and asked to return them with any flies and the
 relevant metadata at the end of each season. Flies of any age were also
 accepted from entomologists, and anyone who wanted a Hippoboscid
 identified via the Hippoboscidae and Nycteribiidae Recording Scheme. Flies
 were identified by the author using published keys and a binocular
 microscope.  The species included are:
 <em>Ornithomya avicularia, Ornithomya chloropus, Ornithomya
 fringillina, Ornithomya biloba, Icosta minor, Crataerina pallida,
 Stenepteryx hirundinis, Pseudolynchia garzettae, Lipoptena cervi,
 Melophagus ovinus</em> and <em>Hippobosca
 equina</em>. Host data has been removed to
 protect the location of protected and rare breeding species. For the same
 reason location names have been omitted and data is only given as a 1 km
 Ordnance Survey grid square for the United Kingdom and Isle of Man, and a
 10 km grid square for the Republic of Ireland.

 [https://doi.org/10.5061/dryad.zs7h44jkh](https://doi.org/10.5061/dryad.zs7h44jkh) ## Description of the data and file structure These data were collected in order to map the ranges of the Hippoboscidae across the United Kingdom (UK), including basic mapping and Maximum entropy species distribution modelling (Maxent SDMs). The dataset also includes data from the Republic of Ireland and Isle of Man. ### Files and variables #### File: 2024MappingtheUKsFlatFliesLocationData.csv **Description:**  ##### Variables * FFsp: The species of flat fly/ louse fly/ ked/ Hippoboscid. The species are indicated by the first letter of the genus, followed by a fullstop (period), and the species name with no spaces. Thus *Ornithomya avicularia* is "O.avicularia", *Crataerina pallida* is "C.pallida", etc.. * FromPuparium: yes (y) or no (n), indicates whether a fly was collected as a puparium, so that those that were collected from puparia can be removed from the dataset for analyses of their phenology, as being kept indoors where it is warmer may have changed their rate of development or length of diapause. * DateCollected: Date on which the fly was collected, or date of adult emergence if originally collected as a puparium, given in the format YYYY-MM-DD. * CountyOrViceCounty: either the County or Vice County from which the specimen was collected. * Monad: the 1 km Ordnance Survey Grid Square (WGS84) from which UK and Isle of Man flies were collected. * TenkUK: the 10 km Ordnance Survey Grid Square (WGS84) from which UK and Isle of Man flies were collected. * TenkIreland: the 10 km Irish Grid Square (Irish Transverse Mercator, ITM, projection) from which Irish flies were collected. * Altitude: altitude of the collection site in meters above sea level. * VCno: Vice county number (UK and Isle of Man). All missing values are indicated by blank squares. ## Code/software This is a comma separated file, .csv file that should be readable on a wide range of software. ## Access information Other publicly accessible locations of the data: * Not applicable Data was derived from the following sources: * Not applicable
