The primary aims of the Society are to encourage interest in arachnology in people of all ages and to generate, promote and disseminate arachnological knowledge and understanding by all suitable means. In particular, it works to foster co-operation between amateur and professional arachnologists. It maintains an extensive
library of books, monographs and reprints (many as pdf files), which can be made available to members upon request. The society is headed by a council comprising a President, Vice-President, Secretary, Meetings Secretary, Treasurer and Membership Development Officer. Other council posts include: Librarian, Editors of both
Arachnology and the Newsletter, Distribution Manager, Sales Manager, Conservation Officer, Education & Publicity Officer, Web Master, and the Organisers of the respective Spider, Harvestman and
Pseudoscorpion Recording Schemes, as well as additional ordinary council members. The society currently has a series of subcommittees drawn from council, whose focus is on strategy, conservation and education & publicity.
Publications The BAS produces two regular publications, distributed together three times a year.
Arachnology Arachnology [formerly the
Bulletin of the British Arachnological Society] is a peer-reviewed
academic journal, publishing research papers on all aspects of arachnid biology, excluding mites. As of 2010, fifteen volumes have been published, with each volume spread over a number of years. Initially edited by John Crocker (1970–1973), and then Eric Duffey (1974) the Bulletin was edited for many years (1974–2011) by Peter Merrett. From mid-2011 editorship was taken over by Paul Selden.
Newsletter The
Newsletter of the British Arachnological Society is a more informal publication, including observations on arachnids and other short papers of academic interest, reports of meetings, obituaries, historical notes and book reviews, etc. Running to 162 volumes as of 2025, it was originally edited by arachnologists John Parker (issues 1–50), John Dalingwater (issues 51–100), Richard Gallon (issues 101–152) and Danniella Sherwood (issues 153-161). Since issue 162 it is now edited by a team of voluntary BAS members. It formerly included the
Spider Recording Scheme News, a supplement (edited formerly by Peter Harvey and then Richard Gallon) largely devoted to the occurrence, distribution and autecology of spiders and other arachnids within the British Isles; including rare or difficult to identify species.
Other publications As well as a ''Members' Handbook
supplied free to all members, the BAS has also published a number of occasional edited volumes, devoted to special topics: the proceedings of the European Congress of arachnology in Edinburgh and a memorial volume for the scorpion biologist Gary Allan Polis. It has also published two important books: a Provisional Atlas of the British Spiders
and a guide to the Gnaphosid Genera of the World''. It was also partially involved in the publication of Paulo Marcello Brignoli's spider catalogue, early issues of the successor catalogue by
Norman Platnick and the pseudoscorpion catalogue of Mark Harvey.
Meetings The BAS holds an
annual general meeting (AGM and Field Meeting), usually at a field station somewhere in the UK. As well as society business, the meeting invariably includes a field trip to collect spiders and other arachnids in the local area; with a report of the meeting — and the animals collected — published in the
Newsletter. The BAS has hosted an International arachnological meeting (
Exeter in 1977, together with the
Zoological Society of London) and a European arachnological meeting (
Edinburgh in 1997). The BAS is also associated with regular spider identification courses run by the
Field Studies Council. Increasingly, regional meeting and identification workshops are being organised.
Spider Recording Scheme Another key activity of the society is the
Spider Recording Scheme (SRS). The older literature included early distribution maps showing the vice-counties from which spiders had been recorded. In 1987 Clifford Smith became the first National Organiser of the spider recording scheme, collating records of British spiders largely contributed by BAS members. From 1993 to 1999 this role was taken over by David Nellist and from 1999 by Peter Harvey, and now by Richard Gallon. This work first led to the publication of the
Provisional Atlas of British Spiders in 2002 by the
Biological Records Centre, then updated maps in 2006 and the development of the Spider Recording Scheme website in 2010. The
British Arachnological Society Atlas was released in January 2026 and maps the distribution of all British spider, harvestmen and pseudoscorpion species. A checklist of British arachnids linked directly to
distribution maps can be found on the BAS website.
Harvestman and Pseudoscorpion Recording Schemes The
Harvestman Recording Scheme provides information on seasonality and habitats as well as distribution maps, and can be accessed on the SRS website. For pseudoscorpions, a
Pseudoscorpion Recorders Group collects similar information. ==External links==
