Oxybelus
Oxybelus is a genus of wasps in the family Crabronidae. The species are found worldwide except in the Australasian realm. 
They are especially represented in the Palearctic. Oxybelus is the largest genus in Crabronidae, with 264 species known. Oxybelus wasps sometimes gravitate towards people, flying around travellers and landing on them, even when they are shooed away. It is not known why they do it, however it might possibly be them trying to drink sweat for its minerals.
