This introductory field guide to stoneflies includes identification keys for the identification of both stonefly larvae and adults to family level. Reliable identification is possible for specimens over 5 mm in length. Scientific species names are mainly used but these are matched with the common names in the flight calendar at the end of the chart. In Britain, 34 species of stonefly have been recorded, belonging to seven families. Two of the species are, however, possibly extinct and one further species, Isogenus nubecula, appears to have suffered a catastrophic decline; its only known UK site is on the Welsh River Dee. 12 pp., num. color figs, leporello fold [16.7 x 24.5 cm].

The AIDGAP Guide to the Freshwater Leeches of Britain and Ireland is a photo-based identification guide for naturalists and enthusiasts. There are 17 species of free-living freshwater leech in Britain and Ireland. Around half of all these can be identified from live animals in the field, while the rest need microscopic examination. This is the first guide to freshwater leeches for many years. ??Leeches live in all types of water bodies, from ditches, streams and rivers to lakes, ponds, canals and wetlands. in general, there are fewer species in running waters than in standing waters. So if you're familiar with pond dipping, then you have probably found freshwater leeches. Often leeches remain clinging to your tray once you have released everything else back to the pond. Hand-searching potential habitats is also a useful collection method. Target sites include the underside of stones, the base of reeds and rushes and the wet surface of leaf litter. Your garden pond is a good place to start! The first stage is to sort leeches into families. There are between one and five pairs of eyes on the upper surface, with the number and arrangement of eyes important for identifying leech families. Then within each family, photographs and species accounts cover field identification where this is possible. Shrewsbury. FSC Publications. 12 pp., 50 color photos and b/w illustrations, folded leporello gr. 8.
