Very Weird

Got a thin skin? Then look elsewhere. Post a link to an image that you've made, and invite others to offer their critiques. Honesty is encouraged, but please be positive in your constructive criticism. Flaming and just plain nastiness will not be tolerated. Please note that this is not an area for you to showcase your images, nor is this a place for you to show-off where you have been. This is an area for you to post images so that you may share with us a technique that you have mastered, or are trying to master. Typically, no more than about four images should be posted in any one post or thread, and the maximum size of any side of any image should not exceed 950 px.

Forum rules
Please note that image critiquing is a matter of give and take: if you post images for critique, and you then expect to receive criticism, then it is also reasonable, fair and appropriate that, in return, you post your critique of the images of other members here as a matter of courtesy. So please do offer your critique of the images of others; your opinion is important, and will help everyone here enjoy their visit to far greater extent.

Also please note that, unless you state something to the contrary, other members might attempt to repost your image with their own post processing applied. We see this as an acceptable form of critique, but should you prefer that others not modify your work, this is perfectly ok, and you should state this, either within your post, or within your signature.

Images posted here should conform with the general forum guidelines. Image sizes should not exceed 950 pixels along the largest side (height or width) and typically no more than four images per post or thread.

Please also ensure that you have a meaningful location included in your profile. Please refer to the FAQ for details of what "meaningful" is.

Found these little suckers having a bit of a chew. Every so often they would all stand straight up and wave around before returning to eat.

Very strange behavior.

I think they are a type of sawfly larvae, the waving around is part of their defences. If you put your hand close you will find they wave around at it, and if its close enough they will squirt some nasty irritating liquid onto you!
Dont get it into your eyes!
Also kown as spitfires, due to the spitting (squirting) of the liquid.

Great shot !!!! Damian and I are divided - 50/50... could be sawfly larvae (this is the normal defensive behaviour exhibited by sawflies, several species actually exude a punjent liquid from their butts to put off any predators that come near them), but, without seeing the head clearly, can't totally dismiss the possibility that they be beetle larvae ..... and I'm not up enough on the larvae of all of sawfly species to say they definitely are or aren't....

sorry :(

but brilliant shot Mark !! Was this taken with one flash on the bracket?

No Bret, it was yesterday arvo around 17:45 but still plenty of light around. Stopped down to f/32 and had the shutter at 1/500s. The only light to have any effect was the flash. The ambient light would not have any impact.
