Stoneflies AIDGAP

FSC Stoneflies AIDGAP includes identification keys for the identification of both stonefly larvae and adults to family level.

Reliable identification is possible for specimens over 5mm 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. 34 species of stonefly have been recorded in Britain, belonging to seven families.
