Insecte allongé à élytres toujours unicolores d’un rouge sombre, à ponctuation fine et serrée ; pattes antérieures rouges avec l’extrême base des fémurs noire, pattes postérieures entièrement noires.
Détermination :
moyennement difficile.
Espèces proches :
Espèce très proche de S. trisignata avec laquelle elle peut être facilement confondue. La couleur des pattes permettant de facilement éviter cette confusion.
Période d’observation :
Les adultes sont actifs de juin à juillet. L’observation de S. erythroptera est difficile et très rare, le plus souvent par individu isolé, parfois posé sur une fleur ou une branche.
Biologie-éthologie :
Stictoleptura erythroptera est une espèce thermophile liée aux cavités de feuillus (Chêne, Hêtre, Orme, érable, Tilleul, Frêne) dans lesquelles se développent sa larve. Le développement larvaire semble nécessiter des conditions particulières dans des couches de bois dur rouge brun de 1 à 5 centimètres au contact du bois vivant. Le cycle de vie est d’au moins 3 ans.
Biogéographie et écologie :
Stictoleptura erythroptera est présente en Europe moyenne, de la France au Nord de l’Iran et l’Azerbaïdjan. Espèce erratique, rare et localisée dans les forêts ou les zones bocagères présentant de gros arbres à cavités.

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.
