I must that Ryan Clark @RyanClarkNature for helping me with the ID of this male leafcutter bee (Megachile sp. - probably M.willughbiella?).
We get a lot of female leafcutter bees in the garden but this is the first time I can recall seeing a male here.
I found it immediately after a torrential downpour, looking a little bedraggled and clinging with its jaws to a leaf.
I hadn't realised that they have such beautiful eyes.
