Review (by Malcolm Storey)

One of the more heavy-weight of the AIDGAP keys, providing keys to more than 250 British species, although some (eg aquatic Chrysomelidae) only go to genus. Handy tables arrange related species by size range and other useful characters.

Was downloadable from the FSC website, but appears to have been withdrawn.

Examine with x15 or x20 hand lens ( Stereo Microscope is also useful)
Specimen PreparationMounted (carded) or pinned
Identification difficultyStraightforward to moderate. Aedeagus required for some genera, but instructions are given.
