The ECN moths protocol (IM)


Protocol file


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.


Our field activities


Now that autumn has arrived the ECN fieldwork calendar begins to quieten down. We cease monitoring most terrestrial invertebrates apart from spiders. In rivers and lakes we make the last freshwater invertebrate survey of the year.
