Creating a Butterfly Lawn


By Americo N. Bonkewitzz, PhD

Lawn, says Durban butterfly expert, Americo N. Bonkewitzz, gives us the dose of “green” that we like to see every day to feel “reconnected with nature”. But, we keep it neat for our visual pleasure; it is for us. In nature, there is nothing like a lawn; there are grasslands rather or perhaps very short groundcovers. In our gardens, we don’t like natural grass; too untidy, too unruly. In fact, he says, lawn is the most widely grown crop in South Africa, and it's not one that anyone can eat. It requires a tremendous amount of water and occupies an essential space much of which could be given to indigenous grasses that support the local butterfly population, and need no poisons to control. His advice? Rather than a sterile lawn let’s create a useful one, useful for us in that it does connect us with the local natural environment, and for nature by creating a natural green carpet in which they can live.


Americo provides a few suggestions from his latest talk at the Durban Botanic Gardens.


How to create a wild lawn:  

Two ways:

  1. The lazy way: Let the weeds and grasses grow and remove all exotics, letting only the indigenous plants remain, and be happy with that. But, you need to know what is exotic and what is indigenous.

  2. The specialist way: Plant selectively indigenous grasses and forbs. You do need to know your local ecosystem and whether you are targeting a particular animal group: bird garden, butterfly garden or just wildlife garden. It can get complicated.


A butterfly lawn is essentially a habitat for “The Browns” (the Satyrid group of butterflies), and you will have to work with grasses that feed their caterpillars. In fact, a butterfly lawn is not as much lawn as a butterfly grass groundcover or a butterfly grassland.

You will attract mainly the Common Bush Brown (Bicyclus safitza). The male is dark brown and the female lighter in colour, both showing beautiful eye patterns. Melanitis leda, the Evening Brown, is a large butterfly with an incredible mimic colouration. This butterfly group is very fond of fermented fruits, and it is common to find them sucking any ripe fruit on the ground.


The butterfly grasses

  1. Ehrharta erecta (Lamarck's Ehrharta or Panic Veld Grass): This is a soft perennial grass that spreads rapidly mainly by seeds and attracts seed-eating birds. Plants can stand shade or semi shade, and even a sunny spot as long as the area is a bit humid. It has been used in ecological restoration, like dune stabilisation.

  2. Pseudechinolaena polystachya (Dwarf Forest/ Basket Grass), requires shade. It is a creeping, short groundcover, excellent under trees and creates a beautiful scene in semi-shaded open spaces.

  3. Oplismenus hirtellus (Basket Grass). It is a common, perennial cosmopolitan grass that requires shade or semi-shade.  Its seeds attract various animals and birds. The sticky seeds are easily distributed by animals and humans, easily adhering to fur and clothing.

  4. Setaria megaphylla (Broad-leaved Bristle Grass). A very decorative grass with large broad leaves.  Seed attracts birds, particularly Bronze Mannikins.


Engaging the butterfly lawn with other butterfly habitats

Combining with a Swallowtail garden:  Plant a few trees, perhaps in the background of your garden, that attracts swallowtails to your butterfly garden, like Clausena anisata (Horsewood) and Vepris lanceolata (White Ironwood). These will provide some shade or semi-shade for the grasses. These species attract Green-banded Swallowtails, Citrus Swallowtails and Mocker Swallowtails. The grassland level underneath the trees will attract Common Bush Browns.


Adding to the lawn a habitat for Pansies: Among the sunny grasses, you can add a few host plants for Pansies, like the Yellow Pansies, Mother of Pearl and Commodores. Plant Ruellia cordata, Dyschoriste setigera (previously Chaetacanthus setiger) and D. burchellii, and Plectranthus purpuratus. The best way to include these plants is around or near any rockery feature.


Now we need to add some extra attractions for the butterflies by creating small patches of indigenous nectar plants for pollinators, like any of the Vernonias,(now Hilliardiella or Gymnanthemum), Justicia flava, Justicia protracta, Scabiosa species and Pentas.

Then the final touch would be to offer the little extras needed by butterflies, like a birdbath full of fermenting fruits for Charaxes and Browns. They love it. And add rockery features for sunbathing. Many butterflies, like pansies, like to rest on a stone with their wings open wide to warm up during a cool morning.

Offer a few muddy patches for male swallowtails to do lepidopterists call mud puddling behaviour where they drink water containing minerals from the mud. Just completely bury a large container in the ground, add some compost, sprinkle bone meal on top, and fill it up with water – and keep it wet.

About the author: Zoologist and biologist, Americo Nestor Bonkewitzz studied Licenciature in Biology at Universidad Nacional del Sur in Bahia Blanca, Argentina and then earned his doctorate in Zoology from the University of Natal (now University of KwaZulu-Natal) in Pietermaritzburg. In late 1990 he started butterfly farming using indigenous species, targeting the breeding of the Emperor Swallowtail. In 2007 he carried out several butterfly surveys in KwaZulu-Natal, in particular, the extensive butterfly and host plant survey of Mkhondeni-Mpushini area in Pietermaritzburg. In 2010 he got involved in a butterfly project with African Conservation Trust establishing four large community-based butterfly domes along the coastal area of KwaZulu-Natal. In 2015 he established the Butterfly Habitat Garden at Durban Botanic Gardens. He now runs several butterfly training courses and invertebrate modules for Bhejani Nature Training. Americo is focusing now on landscaping for pollinators in open spaces as a final tweak/ tune up in forest rehabilitation.
