Comment: Endemic to the Maghreb, with no recognised subspecies ( Tennent, 1996; Tshikolovets, 2011; Leraut, 2016; Tarrier, 2025e), this species was first recorded in Ceuta by Monasterio et al. (2020). Observations were made from 25 localities within 11 1× 1 km UTM squares between March and October, with peak abundance in June and July. Adults were frequently observed nectaring on M. suaveolens , but also on S. atropurpurea , L. dentata , T. caeruleum , C. fragilis , A. unedo , R. ulmifolius , and I. gibraltarica .
