Hi this is another strange face of insects near Tar lake. As i know they have this kind of flap to protect them from heat of direct sun.hope every body like it.

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 behaviour at high population densities are called locusts.

Digestion and excretion
The digestive system of insects includes a foregut (stomodaeum - the mouth region), a hindgut (proctodaeum - the anal region), and a midgut (mesenteron). The mouth leads to the muscular pharynx (which sucks and swallows), and through the esophagus to the crop. This discharges into the midgut, which leads to the malpighian tubules. These are the chief excretion organs. The hindgut includes intestine parts (including the ileum and rectum), and exits through the anus. Most food is handled in the midgut, but some food residue as well as waste products from the malpighian tubules are managed in the hindgut. These waste products consist mainly of uric acid, urea and a bit of amino acids, and are normally converted into dry pellets before being disposed of.

The salivary glands and midgut secrete digestive enzymes. The midgut secretes protease, lipase, amylase, and invertase, among other enzymes. The particular ones secreted vary with diet.

Reproduction

Grasshoppers matingThe 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).

Hi Babak

this one is amazing ! thanks for posting

I am not sure but I think it might be Pyrgodera armata (Acrididae), one of the many so-called "crested grasshoppers"

the color is very intense compared to a photo that I have, but otherwise very similar

it is considered as a pest, see this site, in Farsi by the way:

Excelente imagen Babak con gran nitidez y contrastantes tonos como puntos fuertes.
Un buen DOF permite captar en foco al insecto produciendo un correcto trasfondo a pesar del POV.
Buen control de la iluminación también.
Bonita disparo.
Agregué esta imagen a mi Tema de Langostas.
Saludos... Ricardo
