[Note Guidelines] Photographer's Note
This series of postings is intended to increase the knowledge on Sulawesi's biodiversity. Except for butterflies, little is known on most other insect groups and on spiders of this huge island. Many new species can be expected to be discovered. Large parts of Sulawesi are only poorly explored also with respect to butterflies, such as the south-eastern Peninsula, Sulawesi-Tenggara.

Please note that I added the additional category
'Shortcomings' to my notes

The picture shows a grasshopper species or better 'stonehopper' in this case.
I found it close to a rivulet flanked by stony edges. When walking along and through the water I recognized that some 'stones' were moving and jumping and a close look showed that these stones were in fact small well-camouflaged hoppers which were hardly detectable on the ground.

The species shown is
- Systolederus ophthalmicus BOLIVAR, 1887
- family: Tetrigidae

I thank Hendrik Devriese from the 'Special Interest Group Tetrigidae' for help in species identification.
Unfortunately, I cannot give further informations on this species. Probably little is known on S. ophthalmicus.

A small rivulet at a rain forest margin, about 20 km east of Kolaka (Indonesia, Southeast-Sulawesi).
I could observe many different species of grasshoppers at this place which I know since many years. It offers an entrance to the rain forest via the rivulet. Usually, there are no paths into the forest.

- limited natural light (ISO 400, exposure 1/30s only)
- no wind
- handheld

- Due to limited light long exposure time leads to non-optimal sharpness, particularly seen on the face/eye of the grasshopper.

Hallo Peter,

Die perfekte Tarnung auf diesem Stein.
Dieser Hüpfer ist sehr interessant, hat unheimlich große Augen.
Super Schuß, herzlichen Dank, ich mag Deine Serie mit Insekten aus Sulawesi sehr, Gruß

Very interesting species with a big head and big eyes. Great focus, lightness and point of view.
Greetings and TFS.

Hello Peter.

A very nice shot of this perfectly camouflaged grasshopper.
Sharpness is very good and with almost the same colors as the surroundig makes it difficult to find, i think.
Therefor a great prestation from you taking such a picture this way.

Gr. Hans

Hi Peter,

Although week light conditions and you had to use a relatively long exposure, you've took an amazing capture indeed. Very good job with the focus and exposure, can make out each and every detail.
TFS and best wishes for 2010!


Hi Peter,

Good photo of this grasshopper with good detail and a nice POV from the side showing the length of his body. Taken with good detail and good depth of field.
Good capture and TFS

Another wonderful species. Quite different from what we see here. tfs.

Hello Peter,

Is strange structure of this grasshopper. It differs significantly from what is usual in these insects, the length of their wings and the arrangement of the head relative to thorax are rare. Leaving aside the slight focus problems that you mention in "Shortcomings" is a good photo and fulfills its mission to make us know the species. Truly a "stonehopper" very interesting.

Thanks for sharing and good documentation

Hello Peter,
It may be a bit soft due to the poor light, but the other aspects of this image and the unusual shape of this species of Sulawesian grasshopper, especially the head and the long wings, make this a fine contribution to TN.
Thank you and best wishes,
