Hi Andrea,

G. canescens seems to attract many bees! - A Anthophora species (male) in your first two images and a honeybee in the IR shoot.

Very nice images!

Best, Nico

Nico, thank you. And thanks especially for the ID of the first bee. It's hard to find the time to look up the bees I'm not familiar with and other such insects.
