These images were taken in the Alicante area of Spain on the 12th July 2019, approximately a mile from the coast. This location is populated with other Bembix species of wasps.
I believe it could be a female Bembix rostrata? Going by the faint markings seen under the see through transparent-jacket, covering the abdominal. Any ideas on the true identification? If so, please do not hesitate to send me an email via the contact form.
Thank you
