"Leaf Insect"

Post by gpmatthews »

This is an image from a slide in my collection. The slide is simply entitled "Leaf Insect". If anyone can tell me the identity of this insect I will be most grateful.

The image is a composite of six images stitched with MS ICE. I have not used stacking.

Though we lean upon the same balustrade, the colours of the mountain are different.

Nice image Graham. The flattened shape and general appearance, with the hooked feet suggest a parasitic louse of some sort. Can't see the mouth parts in this dorsal view. The leaf-shaped appendages are fascinating.

- wasn't absolutely sure,but wondered whether this long feature is in fact the piercing mouth parts of a true bug:

interestingly, you can see some striped muscle central left on the central axis

Here are some more details:

The stitched image above, although viewed from the dorsal aspect was in fact effectively an optical section on the ventral side of the preparation, hence the structure I suspect to be mouth parts is indeed on the underside of the specimen. Here is an 8 image stack using a x40 DIC objective:

and here, using a x16 DIC objective is the dorsal surface of the abdomen:

Finally, as the feet were commented upon, here is a 16 image stack of the feet:

I think it is a hemipteran nymph with hairs highly modified as plastron scales to grip an air bubble.

Can you say a few more words about the dust map? What software did you use to do that?

Very interesting images. It's pretty easy to see why it's called a leaf insect. That guy has his own leaf collection. :)
