I have no way to post a picture so I am sorry you will have to work from 1000 words as they say. I am in Australia where it is high summer, hot and showery at present. A grub that I have never seen before just stripped a fig plant in a pot. All the leaves are reduced to paper thin lace, this took about 24 hrs for a 2ft (60cm) plant as it was fine beforehand. The attackers are up to about 3/4in (18mm) long with segmented bodies and a pair of legs on each segment I think, my eyesight is not that good, lots of legs anyway. Each one has a similar number of segments, about 12. Some are smaller and presumeably given enough food they would all grow bigger. They are yellowish on the underside and dark grey/brown on top and somewhat hairy. One end is blunt and seems to have black mouth parts, the other, the tail I think, is slightly pointed. Oh where is my binocular microscope .... As they appeared so quickly I assume they hatched recently and have grown very fast. If you are able to identify the grub can you also tell me what the adult looks like so I can keep an eye open for them. David

If they were a grub a description wouldn't allow identification anyway without a count of the number and pattern of hairs around the animals anus. What you have are either caterpillars or sawfly larvae. Because they are attacking a potted plant you can ignore the nozzleheads and just hand pick them from the plants and either roll them underfoot or drop them into soapy water.

Check the insect depart at your local university. They will be happy to ID the critter.

I'm sure one of those could help if they know their business. Cheers, Boozo in Adelaide, S.A.
