If supermodels were insects, they’d be butterflies – deceptively fragile-looking and impossibly gorgeous, turning heads whenever they appear. But there’s more to butterflies than just good looks. They do sterling work as pollinators, and a thriving butterfly population is a key indicator of a healthy ecosystem rich in biodiversity. Sadly, due to loss of habitat, pesticide use and changing weather patterns, many butterfly species are in decline, so making your garden butterfly-friendly has never been more important.
