Description	Twenty exuviae of Coenagrion puella were marked and observed for three weeks in 2005. The number of marked exuviae rapidly declined and after 23 days there were only 30% of exuviae left; these were so weather-worn that it was impossible to identify them. To collect 50% of the exuviae it would be necessary to visit a locality 10 days after emergence.
