It is possibly but not yet confirmed:
Species: Atrasana postica
(Article was revised)
I have requested help with the identification of this species earlier, and would like to thank all those involved for their input.
It was about this time last year (April 2011) when I found the striking candy-striped caterpillar on a Dombeya rotundifolia (Wild pear or Drolpeer in Afrikaans) leaf. It was about 2-2.5cm long. When disturbed, it curved the body as in the picture below.
I observed it for quite a while and came back for a second ‘photo shoot’.
I saw it pooped and then something amazing happened. It immediately turned to the poop, took it in the mouth and threw it. It fell a few centimetres away and the caterpillar continued until the poop fell off the leaf. Hygienic little critter, I must say!
The eggs on the body fascinated me but I didn’t think at the time to keep the caterpillar to observe the parasite.
A few weeks later, after a walk through the veldt, I found another of this magnificent species on my shoe. It was much smaller and had fewer, but larger eggs attached to it.
This time however I was determined to find out what was parasitizing this beautiful organism, and I kept the caterpillar in a container in my room.
It was gruesome to witness the larvae consuming the caterpillar alive.
Unfortunately I didn’t take any pictures of the pupae, but I saw the organisms that hatched from it!
It was tiny, tiny wasps and my camera lens was hardly sufficient to capture it, and definitely not sufficient enough to enable identification. But I tried!
I brought a microscope from work and attached a webcam to it to take these pictures and a short video clip, but I can’t post that here.
There are ways described on the Internet to attach a webcam to a microscope, and I have tried several methods but nothing is working really very well at this time. This was taken by just holding the cam to the eyepiece, the only way I could capture any image. It is better than nothing, however.
