[Note Guidelines] Photographer's Note
The shot was taken at 9pm. I was on my way to the temple (Tuesday being famous for Lord Hanuman) and I saw this guy sitting on the top of the car. I immediately went out and took my camera and this guy was jumping from one place to the other. Moreover the street light was not adequate enough for lighting. But somehow I kept chasing the guy and it sat on the top of the windsheet of the car.

Tks for looking and this is dedicated for Alexei Alyokhin- TN friend as I was really impressed with this Michael Schumagger shot and that made me to do this shoot. Thought I can not match him but can learn from him.

Grasshoppers are herbivorous insects of the suborder Caelifera in the order Orthoptera. To distinguish them from bush crickets or katydids, they are sometimes referred to as short-horned grasshoppers. Species that change colour and behavior at high population densities are called locusts.

The 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.

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 30 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.

Reproductive System
===================

The grasshopper's reproductive system consists of the gonads, the ducts which carry sexual products to the exterior, and accessory glands. In males, the testes consist of a number of follicles which hold the spermatocytes as they mature and form packets of elongated spermatozoa. After they are liberated in bundles, these spermatozoa accumulate in the vesicula seminalis (vas deferens).

In females, each ovary consists of ovarioles. These converge upon the two oviducts, which unite to create a common oviduct which carries ripe eggs. Each of the ovarioles consists of a germarium (a mass of cells that form oocytes, nurse cells, and follicular cells) and a series of follicles. The nurse cells nourish the oocytes during early growth stages, and the follicular cells provide materials for the yolk and make the eggshell (chorion).


Six stages of development, from newly-hatched nymph to fully-winged adult. (Melanoplus sanguinipes)During reproduction, the male grasshopper introduces sperm into the vagina through its aedeagus (reproductive organ), and inserts its spermatophore, a package containing the sperm, into the female's ovipositor. The sperm enters the eggs through fine canals called micropyles. The female then lays the fertilized egg pod, using her ovipositor and abdomen to insert the eggs about one to two inches underground, although they can also be laid in plant roots or even manure. The egg pod contains several dozens of tightly-packed eggs that look like thin rice grains. The eggs stay there through the winter, and hatch when the weather has warmed sufficiently. In temperate zones, many grasshoppers spend most of their life as eggs through the "cooler" months (up to 9 months) and the active states (young and adult grasshoppers) live only up to three months. The first nymph to hatch tunnels up through the ground, and the rest follow. Grasshoppers develop through stages and progressively get larger in body and wing size. This development is referred to as hemimetabolous or incomplete metamorphosis since the young are rather similar to the adult.

selam ganesh, Great macro shot and very good composition nice pov and bg with splendid colours. Well done ! Regards ridvan

Decent shot.

Your persistence paid off with an excellent image of the grasshopper. It looks like he's gripping the windshield wiper.

The depth of field is tight on this, but the focus is good. Well done. Reid

Gannu,

Looks like you have hijacked this beautiful cricket in your car. I remember one of the Praying Mantis traveling with us by clinging to our car window. It managed to cling on against side winds at speeds of 90KMPH.

Hello Ganesh,
Nice capture of a grasshopper on a car windscreen wiper with good flash illumination and sharpness.
It would have been even better if we could have seen the tip of the antenna but it's a good shot anyway.
TFS and best wishes, Ivan

Hello Ganesh

This is a very useful POV with good details and nice, natural colours. Excellent notes!

Ravi

Nice look exchange. Perhaps he was talking to you or hitchiking but you didn't hear his voice;)?

Hello Narayanan,
Superb details in this little fellow!
Flash works nicely here, and the colours captured are natural and of great clarity...
Well composed presentation!
Greetings,
