Metisella metis





The Gold Spotted Sylph is a very small butterfly, compare it with the leaves they have settles on. It was quite common in our garden (where all the above were taken), perhaps attracted by our stream. The bright gold and dark brown are unmistakable. The male (top) has a dark brown hind wing underside. The bottom two are of the same individual, I think a female. She has with a lighter brown hind wing underside with gold patches.
The only other place I found it (a single record) was at Ferncliffe.

Pseudonacaduba sichela


Pseudonacaduba sichela sichela, what a mouth full for the Dusky Blue. I found this butterfly mud-puddling at the side of our swimming pool on a cold September evening. It is my only record, possibly because we are at the edge of its distribution, and where its putative foodplant (mundulia spp.) is uncommon.
The genus comprises only two species.

Coeliades forestan


I have only two reasonable records of the Striped Policeman, and both found feeding on animal scat. I remember the first one, tracking after it through the long grass at Bisley, before it eluded me. On returning to the foot path I found it feeding on herbivore droppings, oblivious to me very close approach.
The other I found in our garden, this time feeding on vervet monkey scat.
I don't know whether scat feeding is a male habit, or what purpose it serves the animal. It is well described in male Charaxes.
Steve Woodhall also mentions that the males also mark territory with scent hairs on their posterior abdomen. Is this one scent marking?
Food plants cover a wide range, and include our very invasive Bugweed (Solanum mauritianum.)

I have added the individual feeding on monkey scat.
 



Zophopetes dysmephila


Another Hesperid that found its way into our house one night, the Palm-tree Night-fighter, similar to the Strelitzia Night-fighter. Again, despite a number of self sown Phoenix reclinata (the food plants are palms) in our garden this is my only record. The dots on the hind wing, as well as the colour of the antennae are characteristic, but only the female has the white stripe.

Moltena fiara


The Strelitzia Night-fighter or Banana-tree Night-fighter. Despite having number of self sown Strelitzia nicolai (its only food plant) in our garden. I have only two records of this Hesperid. This is possibly because as its name implies, it is crepuscular, active mainly at dusk. (this one had come into our house (Steve Woodhall mentions attracted to lights.) The only other record was outside our house on a cold day (again my source says that they are only seen during the day on cold days.)
Lovely red eyes and white face and antennae.
It is monotypic.


I found this egg on a strelitzia leaf, and wondered if it belonged to this species

Hypolimnas anthedon








Despite an abundance of nettles in our garden (and Laportia in the KZN_NBG), I have only four records of the Variable Diadem, and all of them in our garden.
The top two photograhs are of an individual newly emerged and blown out of a tree one evening together with two others, still unfurling. As the common name implies there are two forms. The top make rather a mouthful: Hypolimnas anthedon wahlbergi f. wahlbergi. It is a Batesian mimic of Amauris niavius.
The bottom two individuals are form mima, a mimic of Amauris albimaculata.
Both these forms have a blue and/ or pink sheen which is characteristic, as it is with H. misisippus, both male and female.

Crudaria leroma


One of our three Greys, the Silver-spotted Grey. Despite being quite widespread, this is my only photograph. It was a battered old warrior missing most of its right fore-wing. It was sitting rather unsteadily on an acacia, one of its foodplants.
