|Site types that use this protocol||
The Lepidoptera (butterflies and moths) is a large order of insects and is among the best known, both taxonomically and biologically. They are a good indicator group for environmental change. The moth protocol involves sampling by light trap of all the large moths (macrolepidoptera) using the methodology of the Rothamsted Insect Survey. This provides a strong background of expertise to ensure that the Protocol requirements are met, as well as an existing extensive national database which forms the basis for analysing future trends in populations.
Counts by species, collected nightly (weekly at remote sites), are made using the methodology of the Rothamsted Insect Survey.
