I’ve spent years watching people panic when a harmless hoverfly enters a room – they even have we humans convinced that they look like bees and wasps, don’t they? This works well for the hoverfly outdoors; however, not so well when they’re being batted against a kitchen window with a wet tea towel!
Outdoors, however, their Batesian mimicry (named after H W Bates who first described it in 1862) puts them in a category best avoided – the ones that sting and taste nasty – which means they seem to go about their business relatively unscathed.
Nowhere does the hoverfly seem more at home than in flowers – drinking nectar and consuming pollen. They’re certainly fond of this rose (Starlight Symphony – Rose of the year 2019 – I’m unsure if hoverflies formally voted, but they seem to agree with the verdict).
