Sampling comments: "Odonate exuviae were collected on emergent macrophytes at a water depth of 0.2-0.4m along the shore... Exuviae were collected in two ways at each lake --from vegetation in a 8 m x 0.5 m section of the shoreline and from a net erected before the emergence season. The net (8 m long, 0.5 m high) was made out of window screening (mesh size 1rnm) and was held in position in the vegetation by sticks driven into the substrate. Exuviae were collected two-three times every week during the whole emergence period of May 30 - August 20"
