TOPIC: Ficus burtt-davyi moth

Ficus burtt-davyi moth 1 Year ago Karma: 8
Hi

I found 2 (or 3?) fairly large spherical eggs laid singly on Ficus burtt-davyi in Athlone Park, Amanzimtoti on 26 March 2011.



Only one of them hatched, and looked like a little brown piece of twig. I don't seem to have taken photos of it in the early stages, but here it is on 07 April 2011. By then it had developed a really nice reddish (almost plum?) colour and patterns.



It contrasted quite starkly with the bright green of the fig leaves.

Here is a close-up of the rear showing the patterning (the 'tail' was damaged/ kinked in handling'),

and a blurry picture of the front section of the body.

And here is a close-up of the face.

By 12 April 2011 it had become a bit dull in colour, although the patterns were more contrasting.

A significant difference in this instar compared to the former instar was the shape of the 'tail' - it had become blunt. I'm not sure if this was a consequence of the earlier damage or if it is a natural development.


Here is a close-up of the face, showing the larva feeding on a leaf of Ficus burtt-davyi.

By 15 April 2011, the moth larva was even more dull in colour and quite plump. Here is a top view.

Here it is crawling from the palm of my hand on to my wrist.

On 22 April it had made a shelter between the leaves of Ficus burtt-davyi in its tub, and had started to pupate.


Although it had made a shelter, Steve suggested to put some dead leaves and soil in a larger container for it to borrow into. I realized it was past the burrowing stage though, but collected some dead leaves and loamy soil from under a Trichilia dregeana and put this in a larger tub and made a hollow in the soil. I placed the shelter with the pre-pupa inside into the hollow and covered over with three pieces of leaves, ensuring that the pupa was in a hollow, and not being pressed on by the leaves. It pupated successfully and on 25 April I gently moved the leaves aside to get some pictures.

The pupa was elongated, generally light brown, with a pinkish tinge between in the joins of the segments. There were dark spots down the side of the abdomen. The elongated 'nose' was the most striking feature, but I decided not to disturb it too much to get better pictures, and decided to wait until I was sure the shell had hardened.


On 28 April 2011, I decided to take the pupa out to get clearer pictures. It almost looked like a dolphin! Here it is on the palm of my hand.


Here is a close-up of the unusual 'nose'.

But when she hatched out on 10 May 2011 - her nose was a little more refined...

Here is the underside while she was still in the tub.

I was worried she would fly as soon as I opened the lid, but she seemed restful, and I took her outside to put her on the stem of a Syzygium cordatum (about 20 m from where I collected her as an egg) to get some pictures. Here she is on my hand.

Here she is on the Syzygium.


Here she is moved into a safer position on the stem and photographed without flash - Would you have seen her?


And finally - today I found another egg in about the same place on the Ficus burtt-davyi...

Hi Michael

Have some K for this - well done! It's a hawkmoth called Nephele accentifera, and funnily enough we had someone ask us to ID this moth only the other day!

Cheers

Steve

Hi Michael,

Well done on another well recorded life history. N. accentifera has been bred a number of times on different Ficus spp. but not on F. burtt-davyi to my knowledge.

regards,


Hermann
