Tiny pollinator is probably Halictus sexcictus. Most likely native to the Armenian highlands in the southern Caucasus; now spread over the Northern Hemisphere. Invasive species! Edible plant - leaves and young stems raw or cooked; flower buds and flowering stems raw or cooked; a pleasant mild flavour with a delicate sweetness and cabbage-like flavour may give broccoli substitute.
