Keys
Below illustrates the three main keys used for the identification of caddisfly larvae. The Field Studies Council book offers a simple key to help you identify caddis larvae to various taxonomic levels using features visible with a x10 hand lens. It is intended to supplement the Freshwater Biological Association keys that should be used for species level identification.
The Field Studies Council will also be releasing a simple key to the families of adult caddis, which should be available early 2008.
