description Small Whiteface Overview
The Small Whiteface (Leucorrhinia dubia) is a species of dragonfly in the family Libellulidae, native to Europe and parts of northern Asia. First described in 1825, the insect is characterized by its compact body and the distinctive pale coloration on its face, which gives the genus its common name. It is primarily found in bog habitats, where it relies on acidic, nutrient-poor, and largely fish-free sphagnum pools to breed and lay its eggs.
help Small Whiteface FAQ
Where can the Small Whiteface dragonfly be found?
Leucorrhinia dubia occurs across northern and central Europe and extends into northern Asia. It favors acidic bog pools, peatland waters, and small lakes with abundant sphagnum and other emergent vegetation.
How can I distinguish a Small Whiteface from other whitefaces?
Look for the pale face, dark body, and relatively small size, then examine the abdominal markings and wing bases. Separation from Northern White-faced Darter and related Leucorrhinia species may require clear photographs of the abdomen and appendages.
When is the Small Whiteface usually on the wing?
Adults are mainly encountered from late spring through summer, with timing changing by latitude and weather. In northern habitats, June and July are often the most productive months for observation.
Why is peatland conservation important for the Small Whiteface?
Its larvae develop in nutrient-poor bog pools that can be damaged by drainage, peat extraction, pollution, or fish introduction. Protecting intact hydrology preserves both the breeding water and the sphagnum-rich margins used by the species.
