Anax imperator is presently a common species, which is only absent from parts of the northern provinces of Groningen and Friesland. It is found at most larger bodies of standing water. Compared to the pre-1990 period, the species’ range has increased strongly. In the beginning of the 20th century it was rather scarce in the south of the country and almost absent from the north. It is therefore without doubt that the area of distribution has expanded to the north. The northward expansion may be linked to the gradual warming in the last decades.
