Scent and stink
A strong, sweet, slightly powdery scent greeted me in the garden. I tracked it down to the blossom covering the holly tree.
After taking multiple photos trying to catch the bees as they crawled over the blooms, it was only when I downloaded my shots that the stink bug revealed itself.
A more polite name for it is shield bug, after the shape, but ‘stink’ describes what it produces when frightened or squashed.
