Cette leucorrhine sombre et terne se caractérise par une face blanche et la présence de points blancs sur le labium. L'abdomen est brièvement bleu puis noir chez le mâle, noir et jaune chez les femelles. On peut la confondre avec L. caudalis.
Son aire de répartition s'étend du sud-ouest de la France à la Scandinavie et à la Sibérie occidentale. En régression dans de nombreux pays européens, elle est rare et dispersée en France mais localement abondante, devenant très localisée dans le sud et l'ouest.
Elle vit sur divers types d'étangs et de lacs : tourbières à sphaignes, étangs tourbeux acides et anciennes zones d'extraction de lignite, souvent en paysage forestier, également dans certains lacs alcalins pauvres en poissons ou présentant des secteurs abrités. On la retrouve jusqu'à 1150 m d'altitude.
Les larves vivent à la surface des sédiments tourbeux, à proximité des rives. Les mâles adultes, quant à eux, se posent sur les buissons ou les formations herbeuses bordant les étangs tourbeux ou les tourbières, à des endroits où ils ont vue sur l'eau et les sites de ponte possibles. A faible densité, ils montrent de forts comportements territoriaux. On les observe de fin mai (fin avril dans le sud) à mi août avec un pic en juin.
L'espèce est en France très menacée par l'aménagement touristique de la côte atlantique et la conversion de la forêt landaise vers la culture de maïs.

The map presents a summary at the 10 x 10 km grid of the observation data for the species transmitted to the SINP. These data have been subjected to validation filters.
The map presents a reference distribution layer of the species at the scale of departments and marine sectors. The presence and absence data were established by expertise within a network of partners. This reference distribution is used in the validation process of the SINP data at the INPN level.
Corresponds to a report on the basis of at least one observation proved within a period of 10 years (20 years for little-known invertebrates) preceding the year and no presumption of extinction since obtaining the last data nor doubt on reproductive and implemented nature of this population. For migratory species, the presence indicated concerns areas of reproduction.
This status is based on one or more of the following criteria:
This point covers the absence, more difficult by nature to demonstrate than presence. This status is based on one or more of the following criteria:
This status must be assigned to a department in which the presence of the species is casual.
Particular case of absence due to a proven extinction less than a half century ago (older disappearances are treated as "no probable or definite").
In the state of knowledge, we can not comment on the presence or absence in the current department. This is the default status when not comprised in one of the previous categories or whenever there is doubt.
The map shows the global distribution of the species based on GBIF data (Global Biodiversity Information Facility).
