Harvester ants and harvester termites with Malmesbury gousblom

- gardening for biodiversity

Harvester ants

Indigenous ants are a vital part of the web of life, especially these harvester ants which live on seeds. At the entrance to the nest is a heap of husks. Some of the seeds which they take underground into their nests are able to grow, and they work at seed dispersal. They live in “dry areas” - Field guide to insects of South Africa, by Mike Picker, Charles Griffiths, and Alan Weaving.

These ants were carrying bundles of mauve fluff in August 2009. What on earth is it? But ants can’t walk that far, then we saw the seeds of the Malmesbury gousblom. Which to our neighbours is green, nasty, take it away.

Arctotis candida is an annual, restricted to clay soils around Malmesbury - South African Wild Flower Guide 7 – West Coast, by John Manning and Peter Goldblatt.

Arctotis candida in August 2009

One of the Ungardener’s free spirited plants. Leaves like a fleshy version of the dandelion, slightly fluffy and delicately shaped. It trails and sprawls, and is generous with its subtle two toned yellow flowers. The central disc florets are black.

Harvester termites - Tiny assistants clear gravel paths

The soul of the white ant by Eugene Marais. 1925 in Afrikaans, 1937 in English. From Wikipedia - Embittered by the horrors of the Boer War, Marais refused to translate his works into English. His book was plagiarized by Nobel laureate Maurice Maeterlinck, who published "The Life of the White Ant" in 1926, falsely claiming many of Marais' revolutionary ideas as his own.

Now we call white ants termites. Harvester termites. I mulch the garden with chipped prunings. They harvest, inch by inch, and take it away underground, where they digest the cellulose. A few favoured plants get the termite treatment. Disconcerting, when bits of lavender, Pelargonium or Coleonema wave goodbye, as they walk away. Neatly trimmed, taken to the nest entrance, left in the sun to dry, until ready to take down below.

The harvest of the harvester termites

When we first came to our empty plot, the termites were responsible for zoning regulations. We had crop circles, fairy circles. Especially the lush winter weeds were manicured down to perfect velvet like a putting green. Now the harvest is often left stacked up on the gravel path. My tiny six-legged assistants, who are NOT on lunch, unless the weather is grey. They only work when the sun shines. Gathering up the seeds from the ash trees, mowing the winter grass. If I want to defend a waving-in-distress plant, I just have to water it.

The termites with red helmets are the soldiers for defence against ants, white heads are just the workers.

Imagine a lumberjack, lifting a tree as large around as he is and five six seven times as long. Then carrying it across this monumental gravel path. Glacial moraine. They move so fast, the camera and I had great difficulty capturing them.
