By making your garden butterfly-friendly, you are helping create a wilder and more liveable city. Everything in nature is connected, so it’s important to look after even the smallest plants and animals, plus they’re beautiful.
Here’s 6 steps to make your garden butterfly-friendly.
Butterflies start as caterpillars (well, eggs really) and they like to snack on plants.
So if you spot a little caterpillar chomping on your plants, check yourself before pulling out the pesticide to remove them. You’ll need caterpillar snacks to attract butterflies to live in your garden.
To get butterflies in your garden, you must cater for caterpillars too – we won’t have thriving butterflies without giving them somewhere to lay their eggs and something for their babies to eat.
Caterpillars are fussy eaters. Some species, like the once regionally extinct yellowish sedge-skipper, favour just one plant. Caterpillars’ main foods are sedges, native grasses and mistletoes but the specific plants depends on the caterpillar.
The plant the caterpillar eats is usually the same one that the female butterflies lay their eggs on. So, if there’s one butterfly you want to attract, you’ll need to research its favourite plant(s) (aka host plant).
Butterflies don’t eat – they drink! Good tasty options include local wattles (Acacia species), tall scurf-pea (Cullen australasicum), goodenias (Goodenia species) and fanflowers (Scaevola species). The plants butterflies drink from are not usually the same as the ones they lay their eggs on or that their caterpillars eat.
Top tip: Weeds are better than no plants at all, as butterflies may still drink from them. Try gradually removing weeds and replacing them with native plants at the same time, so that there’s always nectar on offer.
Plant different species that flower at different times of the year, focussing on spring to autumn. This gives butterflies more nectar options all year round.
Strong winds can rip butterflies’ delicate wings, so protection from the elements is essential. To achieve this, plant native species of different heights for butterflies to take cover around.
Oddly enough, a patch of bare ground, ideally in a spot that gets wet, will provide water for butterflies – no need for a water dish!
Butterflies rely on the warmth of the sun to increase their body temperature because their bodies can’t regulate themselves. Leaving some rocks in a sunny spot will give them somewhere to warm up and rest.
Butterflies are an essential building block in the environment. Not only are they pollinators (helping plants reproduce) but they are also a food source for other animals, like birds and lizards.
