Praying Mantids in my garden

Over the year the visitors to the garden vary according to the season, the weather, the heat, rain, food, shelter, breeding cycle and probably other conditions we can’t know or measure – we don’t know it all, that’s for sure.

This Praying Mantis (Mantidae Stagomantis) was so well camouflaged that I almost missed her. If it wasn’t for a slight movement of one of her front legs, I would never have seen her.

This gardener’s friend is a voracious little predator and feeds on harmful insects like aphids and fruit flies, with the adults graduating to flies, butterflies and crickets. Some species even eat small hummingbirds, frogs, lizards, and mice.

The “leaf” on her back is actually her wing! I photographed her in one
of our blue Gum trees (Eucalyptus) on our smallholding in Tarlton, South
Africa.

By and large many people regard insects with horror as either pests or revolting creepy-crawly creatures to be avoided or worse still, squashed without mercy. Infamous as they may be, insects play such a vital role in the food chain and the global eco-system of the planet that without them, life as we know it, would cease to exist.

The Praying Mantis (Mantidae Stagomantis – Afrikaans “Hottentotsgod”, literally meaning the god of the Khoi) is named for its prominent front legs, which are bent and held together at an angle that suggests the position of prayer.

Generally, mantises are good for the garden. They’re part of a solution to a pest problem, but they eat beneficials, too. And if nothing else is available, they’ll eat each other! So if you plan having one as a pet, have separate housing for each praying mantis you intend to keep!

The praying mantis is the only insect capable of rotating its head by 180 degrees, and this, combined with very keen eyesight, is used to observe both predators and prey. Incredibly the mantis’ powerful vision extends over 50 feet. And as if this wasn’t enough they also have hearing abilities that exceed the upper limit of human hearing.

Organic gardeners who avoid pesticides may encourage mantises as a form of biological pest control. Did you know that tens of thousands of mantis egg cases are sold each year in some garden stores for this purpose! During autumn, praying mantis females deposit a sticky egg case on the underside of a leaf or on a twig. If the egg case survives winter, the offspring, called nymphs, emerge in late spring or early summer. The nymphs have voracious appetites and typically cannibalize each other if they don’t have an adequate supply of aphids and other small insects. Egg cases are commercially available for placement in landscaping.

She was following my every move as I
moved around the tree to get the best shot. Her little head turned with
every movement I made, seemingly staring me right in the eye all the
while, yet not making the slightest move in case she might give away her
position, perfectly camouflaged amongst the leaves. She chose a good
spot, as her wings looked exactly like the leaves of the Karee she was resting in.

I really am always thrilled when I find a Praying Mantis in my garden – these insects are real characters and are not intimidated easily! When I tried to move the leaves to get a better shot, my finger was summarily grabbed and I got a quick nip for my efforts. That didn’t hurt, but the front legs holding onto my finger certainly would have crushed and fatally injured any insect unlucky enough to venture close. I had quite a time convincing her to let go so I could carry on photographing!

Uittreksel uit Siel van Hottentotsgod

Haar koppie draai al in die rondte opsoek na iets sappigs om die honger pyne te stil. Def is ‘n hottentotsgod wat al ‘n paar winters oorleef het hier in die bos geweste. Sy verlang ook nou al baie na haar mannnetjie wat sy al lank terug opgeëet het. Hy sal mos ook nou al trots gewees het op die kleingoed van so by die hele ses. Met haar voorpoot veeg sy ‘n insek traan uit die oë wat altyd waaksaam moet bly.

Tool tip

Properly maintained quality garden tools are a joy to use and can last for generations. And, like most things, an ounce of prevention is worth a pound of cure. Regularly cleaning and oiling your garden tools will prevent rust, keep them sharper, and allow the handles to stay strong. Start by giving your tools a good scrubbing to remove any mud and grit from the blades and handles. Dry with old towels, then set them aside overnight so they dry completely to avoid trapping moisture. Using a clean rag, apply lubricating oil to both the wooden handle and the metal blade. Rub the oil into the surface then wipe off any excess. The oil will help prevent rust and condition the wood to keep it from absorbing water and prevent cracking. After the handle has dried, apply a second coat of oil to the wood if needed. Tools with fiberglass or composite handles will only need a good cleaning.

Wildlife Tips

PUT UP AN OWL BOX : Owls aren't common garden visitors for most, but if you know they are around, it's worth providing extra nesting sites. General Owl boxes are bigger than ordinary bird boxes. They're shaped according to the needs of the species. Barn owl boxes are large and square, or sometimes triangular, with a ledge outside the entrance for young owls to stand on. Barn owls like to nest in a solitary tree on the edge of woodland, between 3 and 5m above the ground. Keep out cold drafts by facing all owl boxes away from prevailing winds. It also makes it easier for parents to fly to the entrance. If you fix the owl box to a tree, use a strap to keep it in place so you don’t damage the trunk. As with all nest boxes, do not disturb the box for cleaning until you are sure that the young have left. Tawny owls in particular can be aggressive when protecting their young. Don’t be disappointed if your box stays empty for the first year. Birds often choose a nesting site during the autumn, winter or early spring. Leave the box where it is for the winter and it could be a nice dry place for birds to roost when the weather’s bad. Please do not unnecessarily disturb the birds and never remove any eggs from the nest.

Leave those leaves! I know many gardeners don't like the 'messy' look of fallen leaves, but they have a lot of benefit to wildlife and your garden. Many wildlife species live in or rely on the leaf layer to find food and other habitat, including toads, shrews, earthworms and many insect species. From a gardening perspective, fallen leaves offer a double benefit. Leaves form a natural mulch that helps suppress weeds and at the same time fertilize the soil as they break down. Why spend money on mulch and fertilizer when you can make your own?

More about me

I've been gardening ever since a child, when I spent time with my father in his vegetable garden. But my fascination with Echeverias started in the 1980's, when my father gave me a pot with five Echeverias, which turned out to be E. imbricata. At first I wasn't much interested in them and planted them in some obscure corner of the garden and completely forgot about them. How great was my surprise when, a couple of months later, I noticed that they had spread and made a beautiful display - I was hooked!

It is utterly forbidden to be half-hearted about gardening. You have got to love your garden whether you like it or not.
