Land slugs

Slug, or land slug, is a common name for any apparently shell-less terrestrial gastropod mollusc.

A Slug feeding on a little piece of mushroom I offered him.

Slugs aren't toxic (and are mostly just meat and skin), they in fact have no way of harming you unless you eat them. Considering that you are a rational human being who doesn't put slimy, gross bugs into your mouth, this shouldn't be a problem. It may, however, be an issue for your pets.

Slugs provide a crucial food source for other wildlife (Thrushes just love them!) andmany species are key composters, helping to breakdown decomposing vegetation. Unlike snails, they are not a serious threat to your garden plants, coming out of hiding after dark in search of food, mostly decomposing vegetation as mentioned above. If you have paving in your garden, you will often see the silver, slimy trails they leave behind.

Bread is not actually good for slugs or snails, but she managed to snag this little piece before I could remove it. Please also note that salt is CERTAIN DEATH for slugs and snails, so if you are interested in having these fascinating little creatures in your garden, please do not feed anything containing salt. Thank you. 

When in motion, it is about 35 to 50mm (1.5 inches long). Adult slugs overwinter and can lay clutches of eggs when environmental conditions are right. A slug's life expectancy is from 6 - 12 months, according to Google, and some up to 18 months.

I decided to keep Ms. Slug overnight and after she’d had her fill of mushroom and lettuce, my slug decided to have a nap. However, after about 3 hours she started walking around (or should I say sliding), so I released her back into the garden. 

Slugs will sleep on and off for several hours at a time but then might stay awake for 30 hours without a break.

It has been about a week since our first encounter and since then she’s appeared every evening at dusk, snacking on the mushrooms and other vegetables I leave out for her.

Close up, admire the telescopic eye and feeler stalks on the head; peer into the large breathing hole, or pneumostome, down the right side of the body (like snails, slugs are not bilaterally symetrical); and admire the rhythmic muscular ripples on its belly as a large, moist slug glides smoothly and effortlessly up a sheet of glass.

Giant African Land Snail

 

A Giant African Snail (Lissachatina fulica) found in my garden. KwaZulu Natal is South Africa’s Texas, everything is bigger! 

This is one of the most damaging snails in the world because it consumes at least 500 types of plants and can cause structural damage to plaster and stucco structures. This snail can also carry a parasitic nematode that can lead to meningitis in humans.

However, Google says “snail therapy” is suitable for both young and aging skin, helps to fight a variety of aesthetic defects. Reviews indicate that Achatina mucus has a beneficial effect on the skin and does not cause side effects.

7-10 cm (3-4 in.) (Shell length)

Gaudy Commodore

Precis octavia male or Gaudy Commodore in my garden. The wingspan of the Gaudy Commodore is 50-63 mm, and the colours of the males and females are the same. The females lay eggs on shoots of specific host plants, mostly grassland plants in the mint family, including Plectranthus, which is obviously why it chose to visit me. 

The Gaudy Commodore breeds twice a year and the subspecies Precis octavia sesamus has a wet season form and a dry season form. In this photo, taken now in late winter in August, the dry season form colouration can be seen. In the wet season form the colouration is predominantly red-orange. The two forms are so different that it is hard to believe that they are forms of the same species of butterfly. 

The caterpillars of the Gaudy Commodore are about 45 mm in length and they are tawny brown in colour, banded with black. They carry branched spines along the length of their body and a pair of spines on the head. 

Even those who don’t like caterpillars tend to like butterflies, perhaps forgetting that caterpillars are the larvae of butterflies?

Françoise Hardy - Dans le monde entier (1965)

My all-time favourite..  (17 Jan 1944 - 11 June2024 - RIP)

I don't normally do obituaries, especially if they're not fauna or flora related, but this lady held a special place in my heart when I was growing up.

South African Paper Wasps—Vespidae

 Don’t reach for the Doom!

These are the most common wasps and all species build papery multi-celled nests of chewed wood pulp and saliva. 

They are highly social. So if you see a paper wasp nest under the eaves, do not reach for the Doom. They are not aggressive and will not attack you. They are keeping the ecosystem in your garden in equilibrium, by preying on insect larvae and aphids.

They gather fibers from dead wood and plant stems, which they mix with saliva, and use it to construct nests made of gray or brown papery material. The resultant wood pulp is remarkably strong.

“Paper wasps have an interesting lifestyle. The nests are usually founded by a single queen. A mated female from the parental nest emerges in spring and starts building the nest. She becomes the queen and is soon joined by other mated females from the same nest to form a colony. The late-comers are relegated to the worker caste. After the queen has started construction of the first hexagonal cell of the nest, the worker females add more concentric circles of cells to enlarge it.

The queen will lay all the eggs. The worker females are destined to be the workers – building the nest, hunting for food and minding the offspring.”

Black Snow

It’s sugar cane burning season in South Africa and here in KwaZulu Natal, it starts late-winter (July/August) and continues into early-summer. 

 

Before the sugar cane can be harvested, it must first be burned to remove the outer leaves and make it easier to cut.

While this process is necessary for the sugar cane industry, it can have some negative effects on the environment and human health. The burning of sugar cane releases large amounts of smoke and particulate matter into the air, which can cause respiratory problems and other health issues for people living nearby.

At the start of the sugar cane burning season in Southern Africa, many residents brace themselves for what has become known as ‘black snow.’ This term refers to the thick, black smoke and soot that fills the air as sugar cane fields are burned to prepare for harvest.

Sunsets teach us

It was sunsets that taught me that beauty sometimes only lasts for a couple of moments. By the time I turned my back, went inside and closed the door, all the fiery orange had disappeared, leaving only a few splashes of pink and grey. 

I also found out that sunset or dusk is a good time for photography--it lends a certain peaceful quality to the garden.
