Characteristics
The Caelifera have antennae that are shorter than the body, and short ovipositors. Those species that make easily heard noises usually do so by rubbing the hind femurs against the forewings or abdomen, or by snapping the wings in flight. Tympana, if present, are on the sides of the first abdominal segment. The front femora are long and strong, fitted for leaping. Generally they are winged, but hind wings are membranous while front wings (tegmina) are coriaceous and unfitted for flying. Females are normally larger than males, with short ovipositors.

They are easily confused with the other sub-order of Orthoptera, Ensifera. In fact up to few years ago both sub-orders were classified together in the order of Orthoptera, but are different in many aspects, such as the number of segments in their antennae and ovipositor. Ensiferans, have antennae with at least 30 segments, and caeliferans have less. In evolutionary terms, the split between the Caelifera and the Ensifera is not more recent than the Permo-Triassic boundary (Zeuner 1939).

Taxonomically, Borror and White (1970) note that the hind femora are usually enlarged, tarsi have three segments or less, antennae are relatively short, tympana are usually present on the sides fo the first abdomenal segment, and the ovipositor is short. Taxonomic descriptions of the families are more specific.

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.

Families
The Sub-Order consists of five major families:

Acrididae (grasshoppers and short-horned grasshoppers)
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 characterised by the adults wings and legs, which are well developed and may be brightly coloured. As well as singing by rubbing their legs together, there may also be a visual display. The Acrididae family includes the Locust, which can be a serious economic pest.

Eggs are 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.

Hi Philip, very good macro of the grasshopper. He nice and sharp and the details and colours are so clear. I see he only has one feeler / antennae too. Well done.

Hi Phlip,

It's good to see you post again. The picture is nice, the colors are really beautiful and the details are sharp. I find the POV a little strange as it looks as if you hold the camera tilted (but I assume the insect is sitting on a slightly titled tile?). It's also a pity that you cut off it's feelhorn. Well done & TFS!

Regards,
Pieter

Hi Philip. Lovely shot. The head looks a little soft but the rest is beautifully sharp so maybe it needed slightly greater DOF. Your exposure, colours and composition are perfect. I love the detail in the markings and the BG is great. Your note is fantastic too, TFS :)

Hi Philip, very nice shot of this cricket. I think your opening line confirms that suborder is incorrect, this specimen has very long antennae and a very long ovipositor! :-) I think it should be Ensifera.

Very nice shot, good details and composition, well done!

Hi Philip, very nice shot of this common cricket of the east Mediterranean. The ones in Turkey is greener and less patterened. Good colours and composition.
Well done.

Quelle netteté et quelles couleurs! Une très belle photo, Philip, d'un criquet très original (pour moi en tout cas). Ces couleurs brillantes donnent l'impression qu'il est en métal émaillé. Très bien rendu dans une lumière douce qui rend les détails bien précis.
