GRASSHOPPER

The grasshopper is an insect of the suborder Caelifera in the order Orthoptera. To distinguish it from bush crickets or katydids, it is sometimes referred to as the short-horned grasshopper. Species that change color and behaviour at high population densities are called locusts.

Grasshoppers have antennae that are almost always shorter than the body (sometimes filamentous), and short ovipositors. They also have pinchers or mandibles that cut and tear off food. 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 at the end of the abdomen used to dig in sand when egg laying.

The digestive system of insects includes a foregut (stomodaeum, the mouth region), a midgut (mesenteron), and a hindgut (proctodaeum, the anal region). The mouth leads to the muscular pharynx, and through the esophagus to the crop. This 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 amino acids, and are normally converted into dry pellets before being disposed of.

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.

Grasshoppers have open circulatory systems, with most of the body fluid (haemolymph) filling body cavities and appendages. The one closed organ, the dorsal vessel, extends from the head through the thorax to the hind end. It is a continuous tube with two regions: the heart, which is restricted to the abdomen; and the aorta, which extends from the heart to the head through the thorax. Haemolymph is pumped forward from the hind end and the sides of the body through a series of valved chambers, each of which contains a pair of lateral openings (ostia).

With many varieties being green, grasshoppers in green grass are difficult to spot by predators.

Hello Marius,
great capture of this Grasshopper with excellent sharpness and lovely details. I also like the various green tones and nicely blurred background.
Best wishes,
Helmut

This is a pic as best as best can be. Everything is fine, but i wonder whether you use flash diffuser or not. My question may be invalid if you have not fired the flash at all, but since your exif data doesn't reveal that and there is some harsh lighting on the subject, i guessed so ! But a fantastic and high quality pic none the less !
TFS,
Nitin

Hello Marius,
I haven't seen yet this species, so think. I know enough poor grasshoppers in general. Although it's almost black but the details are visible very well.
