Stenurella approximans, West-Mediterranean species known from Portugal, Spain and Morocco, has been described from Algeciras environs (Andalusia, Spain) as Strangalia approximans by Wilhelm Gottlob Rosenhauer in 1856 [❖]. The larval biology of the species has not been described, but most likely it will be similar to other species of the genus Stenurella - i.e. development in decaying wood of deciduous and coniferous trees. Adults, active from May to August, are diurnal and anthophilous [✮][▽].

Body length:	9 - 13 mm
Life cycle:	2 years
Adults in:	May - August
Host plant:	unknown, but most likely similar to other species of the genus Stenurella
Distribution:	Western Mediterranean area (Portugal, Spain and Morocco)
