Punaise élancée uniformément brun foncé. Tête triangulaire, l'espace entre les yeux plus large que le bord postérieur du pronotum. Yeux proéminents, antennes parfois éclaircies mais globalement brunes. Pronotum trapézoïdal aux bords huméraux arrondis. Fémurs postérieurs armés de 3 ou 4 dents sur leur face intérieure, et aussi épais que les autres fémurs.
Juin à octobre avec le plus d'observations en août.
Biologie-éthologie :
Elle vit surtout sur des légumineuses arbustives à fleurs jaunes comme les ajoncs, bugranes, cytises et genêts (Fabaceae), ainsi que sur des luzernes. Elle a aussi été observée sur d'autres familles végétales, comme les euphorbes (Euphorbiaceae) ou les bruyères (Ericaceae). Les jeunes ressemblent à des fourmis et peuvent hiverner à ce stade dans des fourmilières, mais les adultes hivernent aussi, dans la litière puis y pondent ou directement sur les plantes, fin juin, et la nouvelle génération apparait à partir de juillet.
Biogéographie et écologie :
Espèce présente sur tout le continent paléarctique depuis l'Europe de l'Ouest et l'Afrique du Nord jusqu'en Chine en passant par le Moyen-Orient, mais elle est moins fréquente au sud dans les biotopes secs. On la trouve jusqu'à 62° de latitude nord en Finlande. Elle a été importée aux Etats-Unis et au Canada. Elle vit dans les milieux humides, verts et herbeux : marais, tourbières, bords d'étangs et de cours d'eau, prairies hygrophiles, lisières forestières et jardins.
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.
