On October 26, 2006 a young female Leucorrhinia rubicunda was found in the Bargerveen peat bog. The observation of a female in autumn is very exceptional as this is a typical spring species and the earliest Leucorrhinia in temperate lowlands. A possible explanation could be the extreme hot summer and spring causing an exceptionally high water temperature, resulting in higher food availability and probably faster larval growth. The exceptionally high temperatures in October may have prevented this female to diapause.
