Le fond des ailes est marron-gris. Les ailes antérieures possèdent un point noir cellulaire sur le dessus et sont tigrées sur leurs côtes. Les ailes postérieures sont festonnées.
Détermination :
En France métropolitaine, la détermination est assez facile lorsque l'on connaît les critères distinctifs.
Espèces proches :
L'adulte peut être confondu avec certaines espèces d'un autre genre de géomètres : les Eupithecia. Néanmoins, contrairement à ces dernières, les ailes postérieures de la Larentie mouchetée sont festonnées.
Période d'observation :
L'imago peut s'observer de mai à août.
Biologie-éthologie :
La Larentie mouchetée a 1 à 2 générations par an selon la latitude et l'altitude. L'adulte a une activité nocturne. Ce sont les chrysalides qui passent l'hiver. Les chenilles, monophages, se nourrissent des fleurs et des feuilles des Lysimachia spp.
Biogéographique et écologie :
Paléarctique, elle est présente un peu partout en Europe, des Pyrénées espagnoles à l'Angleterre jusqu'au sud de la Fennoscandie, dans les Alpes du Nord jusqu'en Roumanie, puis à travers le sud de la taïga sibérienne jusqu'à la Corée et le Japon. Cette espèce affectionne les prairies humides, les marais, les tourbières et les lisières humides des ripisylves fraîches. Elle est observée à l'étage collinéen jusqu'à 700 m d'altitude.

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.

Current distribution in metropolitan France
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.

Certain presence
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.
Probable presence
This status is based on one or more of the following criteria:
search of species incomplete but presence of supportive environments;
ecology of the species consistent with the hypothesis of his presence;
the last reliable sighting is older than 10 years compared to the reference date, no recent specific research and no presumption of extinction from that date [vertebrates, invertebrates and plants well studied (rhopalocera, grasshoppers, dragonflies ...)] ;
the last reliable observation being older than 20 years, no recent specific research and no presumption of extinction from that date [poorly known taxa: fungus, many invertebrates...].
Probable or certain absence
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:
intensive but unsuccessful targeted research;
lack of adequate environments;
unobserved species while its presence is easily detected;
unlikely presence for historical or biogeographical reasons.
This status must be assigned to a department in which the presence of the species is casual.
Absence due to a proven extinction
Particular case of absence due to a proven extinction less than a half century ago (older disappearances are treated as "no probable or definite").
No information
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.
