Hi there and welcome!
A nice picture, obviously your diffuser works well!
Looks like you've photographed a male
Osmia bicornis here, obviously refueling nectar on a
Muscari. These are out in our garden too at the moment.
If you don't know already, you might be interested that one can easily provide nest sites for this bee species and other hymenopterans (and their parasites) by manufacturing a
"hotel hymenoptera" from hard wood blocks with drilled holes - shouldn't be a challenge for "Geppetto"

.
The blocks should be put up in a sunny spot like a wall or fence facing S, SW or W with a board ontop as rain shelter for the end grain.
Left out there the whole year round such a "hotel hymenoptera" is a good place for observing some interesting insect behaviour, and for photographing it without having to bend down, or to get down on one's knees, if the wood blocks are put up at a convenient height that is.
