Discovering Millipedes, Centipedes, Woodlice & other Isopods in Britain & Ireland

British Myriapod and Isopod Group (BMIG) aims to improve awareness and knowledge of centipedes, millipedes, pauropods & symphylans (the Myriapoda) and woodlice, waterlice  & intertidal isopods (the Isopoda) in Britain and Ireland.

Recording Schemes

The group is responsible for four National Recording Schemes, one each for centipedes, millipedes, woodlice & waterlice and intertidal marine isopods


The BMIG Newsletter is produced twice a year and the more formal BMIG Bulletin is published annually.

Field Meetings

We hold an annual field meeting to which all are welcome, beginners and experts alike.

Species information

There is a page for each British and Irish species of centipede, millipede, woodlouse and waterlouse (including the terrestrial landhopper) and intertidal marine isopods. The aim is to include a brief account for each species, including distribution map, images, and identification hints.
