New life

Summer is the time of new life - baby chicks and  birds are hatching, my bathroom court-yard garden is full of new baby lizards and virtually every day I witness the birth of something.

Yesterday morning, as I was packing my garden tool basket, I came upon a spent cocoon and it was rather large, almost three inches. I wondered what on earth could have hatched, obviously a moth and I hoped she was still around somewhere. A search revealed her sitting on the edge of the patio step, trying to unfold her shrivelled wings. I quickly picked her up and carried her to the nearest tree, and only afterwards thought that I should have taken a photo of her before picking her up!

Once in the tree she started crawling up and vibrating her wings, making it very difficult to get a photo!

She's not this blurry in real life! Even while sitting still for a moment, her wings were trilling and vibrating, pumping blood through to strengthen them. I've come to the conclusion that she's one of the Hawk moths but have not been able to find a positive identification (there are 7 000 species of moths in South Africa!)

The Sphingidae are a family of moths (Lepidoptera), commonly known as hawk moths, sphinx moths, and hornworms; it includes about 1,450 species. They are moderate to large in size and are distinguished among moths for their rapid, sustained flying ability. Their narrow wings and streamlined abdomens are adaptations for rapid flight.

Some hawk moths, such as the hummingbird hawk moth or the white-lined sphinx, hover in mid-air while they feed on nectar from flowers, so are sometimes mistaken for hummingbirds. This hovering capability has evolved only four times in nectar feeders: in hummingbirds, certain bats, hoverflies, and these sphingids (an example of convergent evolution). Sphingids have been much studied for their flying ability, especially their ability to move rapidly from side to side while hovering, called 'swing-hovering' or 'side-slipping.' This is thought to have evolved to deal with ambush predators that lie in wait in flowers.

And now there's a spin to the tale. As soon as I finished photographing her and had moved away, I noticed my Robin in the tree, hopping from branch to branch, trying to get a good look at what might be the biggest snack of the week! I immediately climbed up the lower branches of the tree, retrieved her and took her to another tree at the other end of the garden, hoping the Robin didn't know what I was doing. Upon my return to the patio, I noticed the Robin still hopping around in the tree, trying to find out what had happened and where that snack has disappeared to all of a sudden! Hopefully he, or any of the other birds, won't find her hidden in the foliage of the other tree.

Just before dusk I checked on her, and she was quietly hanging onto the trunk of the tree, quite well camouflaged, so hopefully she would be safe until night time. All moths are nocturnal and some species fly only for short periods either around dusk or dawn, while other species only appear later in the evening and others around midnight, but such species may occasionally be seen feeding at flowers during the day. A few common species in Africa, such as Cephonodes hylas virescens (the Oriental bee hawk), Leucostrophus hirundo, and Macroglossum trochilus, are diurnal.

Most species of Hawk moths are multivoltine, capable of producing several generations a year if weather conditions permit. When I checked early this morning, she was nowhere to be found and hopefully she survived the dangers of the night. And maybe I'll be seeing a lot more of these moths in the future.

Hairy wonders

As I was watering the garden this morning, I discovered a whole clump of caterpillars at the base of my Acacia karroo tree. These are the larvae of the Lappet Moth and I am lucky enough to have them hatch in my garden every October.

Their appearance also coincides with the return in mid-October of the Red-chested Cuckoo (Cuculus solitarius – Piet-my-Vrou) as they make out a large part of this Cuckoo’s diet.

Eutricha capensis, the Cape lappet moth, is a species of moth in the family Lasiocampidae primarily found in South Africa. During the larval stage, cape lappets feed on a wide variety of African plants and can often be found aggregating in gardens. The caterpillars are brightly coloured and conspicuously hairy, while the bulky adult moths are mostly brown and much less striking in appearance.

I also found another clump at the base of one of the White Karee's (Rhus viminalis) and I think they have chosen their spot well, for I doubt that the Red-chested Cuckoo will go onto the ground in my garden.

If you look close enough, you will see some water droplets on them. Luckily I saw them just in time before wetting them completely with the hosepipe! Be careful of touching these deceptively soft-looking beauties, the hairs stick to whatever they come into contact with and and can cause an irritating, itchy rash.

The adult moths are large and stocky, with an average wingspan of about 70 mm (2.8 in). Both hind wings and fore wings are reddish brown. The fore wings are flecked with yellow and bear three wavy white stripes. Females are typically paler in colour and larger than males.

I will be keeping a close eye on them over the next few days and hopefully I can capture the adults emerging.

Speckled Emperor Moth

What the caterpillar calls the end of the world, the master calls a butterfly.
~ Richard Bach

A Speckled Emperor Moth, (Wattled Emperor Moth, Mopane worm) resting on a Restios plant in my garden. It is from the Saturniidae (Silk Moths) family. I actually found her inside the house and brought her out to safety (not sure how SAFE it is...?) and she seemed quite content to just rest a while before disappearing into the thickets.

This moth is widely distributed throughout southern, central and east Africa. Across most of its distribution, the species is bivoltine, with the first generation emerging from pupation in November to December and the second in February to March, only in more arid areas is it univoltine.

Adult moths lay a single cluster of 50 to 200 eggs around twigs or on the leaves of host plants over a two month period. After approximately ten days, the larvae emerge and then pass through five instars before pupation. Instars I to III of the caterpillars are strictly gregarious and will forage together in aggregations of 20 to 200 individuals. After moulting into instar IV, caterpillars disperse immediately to become solitary. The larval stage lasts approximately 6 weeks, during which time the caterpillars undergo a 4000 fold increase in body mass. At the end of the larval stage, the fifth instar caterpillars burrow into the soil, where they undergo a period of diapause. Eclosion occurs either one or six to seven months after pupation, depending on the generation. The non-feeding adult stage lasts only two to three days, during which time the only function of the imago is to find receptive mates and to oviposit.
