Promoting the study of Centipedes, Millipedes and Woodlice in Britain and Ireland

British Myriapod and Isopod Group (BMIG) aims to actively develop identification, training and recording relevant to improving the knowledge and conservation of centipedes, millipedes, pauropods & symphylans (the Myriapoda) and woodlice & waterlice (the Isopoda) found in Britain and Ireland.

Recording Schemes

The group is responsible for three National Recording Schemes, one each for centipedes, millipedes and woodlice & waterlice.


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.
