Woodlouse & Waterlouse Recording Scheme Organiser: Steve Gregory
The Non-marine Isopod Recording Scheme was established in 1968 to collate biological records of all species of Terrestrial Woodlice (suborder Oniscidea) and the Aquatic Waterlice (or water-slaters) (suborder Asellota). An analysis of the ecological data for woodlice was undertaken for the publication of the Woodlice in Britain and Ireland (Harding & Sutton, 1985). Further distibutional data is presented in the updated atlas Woodlice and Waterlice in Britain and Ireland (Gregory, 2009).
The recording scheme also collates records for the Landhopper Arcitalitrus dorrieni (also known as the Woodhopper or Lawn Shrimp) since it is the only British Amphipod to penetrate inland (the rest are marine or supralittoral).
The scheme welcomes records for all species of woodlice, waterlice or landhoppers. Many of the records presented in the current distribution atlas (Gregory, 2009) are twenty-five years old and are in urgent need of updating. All records, even those for common species or those that don’t add new ‘dots’ to the maps, are valuable. Records accompanied by ecological information are especially welcome.
New contributors to the scheme are most welcome and support and guidance with collection, preservation of specimens and identification will be offered where required.
The scheme organiser is pleased to receive British records for their relevant group. Records may be submitted on recording cards or in electronic spreadsheets. Records are used to produce distribution maps for each species.
Scheme organisers are usually happy to check the identity of individual specimens but please do not send large collections of material without prior agreement. (Please ensure that specimens are sent in appropriate containers that will not be damaged or broken in the post.)
The scheme organisers will only normally deal with British material, but may be able to help with some specimens collected in other countries. Please do not send these without checking first.
