This guidance standard specifies equipment and procedures for collecting floating pupal exuviae of
Chironomidae from aquatic habitats; rivers from source to estuary, canals, ponds, lakes and sea coasts.
Guidance in preparing specimens for subsequent identification is provided. These samples provide
representative data on relative species abundance, suitable for numerical analysis, classification and
monitoring of environmental conditions.
