The Buckinghamshire Invertebrate Group (BIG) studies and records insects and other invertebrates in Buckinghamshire and Milton Keynes. We organise field trips, indoor meetings and training events, and publish an annual bulletin and other resources. Members of the group have a wide range of interests, from microscopic rotifers to garden butterflies.

To find out about BIG meetings and events, see our calendar and join our free mailing list. 

BIG is supported by Buckinghamshire and Milton Keynes Environmental Records Centre and Discover Bucks Museum.
