|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.|
The Caelifera 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 less. In evolutionary terms, the split between the Caelifera and the Ensifera is no more recent than the Permo-Triassic boundary (Zeuner 1939).
Diversity and range
Recent estimates (Kevan 1982; Günther, 1980, 1992; Otte 1994-1995; subsequent literature) indicate some 2,400 valid Caeliferan genera and about 11,000 valid species described to date. Many undescribed species exist, especially in tropical wet forests. The Caelifera are predominantly tropical but most of the superfamilies are represented world wide.
The Sub Order consists primarily of five major families:
• Acrididae (field grasshoppers and locusts)
• Eumastacidae (monkey grasshoppers)
• Tanaoceridae (tanaocerids)
• Tetrigidae (grouse locusts, pygmy grasshoppers, and pygmy locusts)
• Tridactylidae (pygmy mole crickets)
The most important family is Acrididae, consisting of about 10,000 species. The family is characterized by the short, thickened antennae and relatively unmodified anatomy; they are often visually more striking than other Caelifera, due to the adults' wings and legs, which are well developed and may be brightly coloured. As well as singing by rubbing their legs against the wings/abdomen, there may also be a visual display. The Acrididae includes the locusts, which can be serious economic pests.
Eggs are commonly laid in the ground with a foamy substance around them to protect them during incubation; typically the number of eggs laid by a female is between 400 and 500.

I like colours and composition.
And also good sharoness on its face.
I like it.
Wonderful macro shot.I like sharnees, details POV and composition.Lovely colours.Well done.
Great detail Ram and well exposed with nice color and sharp detail. Your grey/tan colored hopper stands out well with this lush green BG/environment :)
Well done & TFS!

Beautiful shot, with bright vivid colours and excellent detail. These hoppers are quite common in Malta but I have never actually seen them on plants. Usually they tend to stay in the soil or on rocky ground. I guess I shall start looking for them also in vegetation, as this makes a more intersesting back drop than soil. Your shot is a graphic example of this.
Excellent details in this little bugger!
Well composed presentation, and the grasshopper is captured in a nice pose...
Good clarity in colours!

Nice shot with good pov. This is a strange looking grasshopper to me. Well done and TFS.
