[Note Guidelines] Photographer's Note
Grasshoppers have antennae that are almost always shorter than the body (sometimes filamentous), and short ovipositors. Those species that make easily heard noises usually do so by rubbing the hind femurs against the forewings or abdomen (stridulation), or by snapping the wings in flight. Tympana, if present, are on the sides of the first abdominal segment. The hind femora are typically long and strong, fitted for leaping. Generally they are winged, but hind wings are membranous while front wings (tegmina) are coriaceous and not fit for flight. Females are normally larger than males, with short ovipositors. Males have a single unpaired plate at the end of the abdomen. Females have two pairs of valves ( triangles) at the end of the abdomen used to dig in sand when egg laying.

They are easily confused with the other sub-order of Orthoptera, Ensifera, but are different in many aspects, such as the number of segments in their antennae and structure of the ovipositor, as well as the location of the tympana and modes of sound production. Ensiferans have antennae with at least 20-24 segments, and caeliferans have fewer. In evolutionary terms, the split between the Caelifera and the Ensifera is no more recent than the Permo-Triassic boundary (Zeuner 1939).

Hello Al,

Excellent detail, sharpness beautiful, well balanced, with a range of brightness outside and fantastic colors. Superb POV!

Jesús

This is wonderful work Al.
The exposure and focus are perfect once again & the composition works beautifully.
Not only a document,but a work of art.
A good note to go with it too.
Very nice work again.
Can you tell me....
do you attach your Raynox 250 straight to the end of your S5 IS lens or do you use an adaptor of some kind?
I'm wanting to get better results with my Raynox 150 on the SX10 IS and would be glad of any advice.
Cheers
Steve
