Hi friends from TN. We call Grasshopper as "Gafanhoto"here in Brazil. I took this pic more then a year ago, but looking for another data I found this one and it is here now. I hope you all enjoy.

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 short-horned grasshoppers. Species that change colour 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. 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).

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.

Hello Francisco,
a splendid macro shot and very beautiful large version, very good sharpness and beautiful natural colours, this grasshopper is like Anacridium aegyptium of Acrididae family:
Acrididae é uma família de insectos do filo artrópodes fitófagos cujo meio de locomoção é o salto, vulgarmente conhecidos por gafanhotos. O seu canto característico é obtido por fricção da face da coxa com uma nervura espessa da asa anterior. Este grupo inclui as espécies que formam grandes enxames com consequências devastadoras para a agricultura dos países afectados

Best regards
Buen fin de semana
