Hello, [Click on the picture to get a better resolution. Click again to come back.]  Pierre Duhem : France : Saint-Leu-la-Forêt : 95320 : 03/05/2021 Altitude : 191 m - Taille : 7-8 mm Réf. : 280954 The female:  Pierre Duhem : France : Saint-Leu-la-Forêt : 95320 : 03/05/2021 Altitude : 191 m - Taille : 7-8 mm Réf. : 281083 The male:  Pierre Duhem : France : Saint-Leu-la-Forêt : 95320 : 03/05/2021 Altitude : 191 m - Taille : 7-8 mm Réf. : 281084 I hesitate between B. lanigerus and B. johannis. Is it possible to decide? Thanks in advance. Pierre Duhem |

Hi Pierre, a lateral view would be nice but to decide between johannis & lanigerus: it's lanigerus: The wing membrane is brownish and the stigma poorly visible - in johannis the membrane is hyaline and the stigma dark brown and clearly visible. B. reticulatus (legs red) & varipes (stigma brown) excluded, too. Greetings, Eric Edited by eklans on 06-05-2021 12:33 |
