Classification follows Orthoptera Species File; see Taxonomy Proposals topic here.
Explanation of Names Ander (1939) first divided the Orthoptera into suborders Caelifera and Ensifera ( OSF).
Apparently from Latin caelare, (noun caelatura), to engrave in relief, plus -fer, bearing (Internet searches) (1)--likely refers to the sculptured integument of many in this group. The related term Ensifera means sword-bearing.
Numbers In North America, five families, about 660 species, most (620 or so) in family Acrididae (totals from individual family pages).
Worldwide, about 2,400 genera, 11,000 species (Internet references).
Identification The group that contains the insects familiar to most people as grasshoppers. Also includes the Pygmy Mole 'Crickets' (Tridactylidae), which are not closely related to crickets. Characteristics:
back legs large, modified for jumping
antennae usually shorter than body
antennae have fewer than 30 segments (more than 30 in Ensifera)
ovipositor short (not obvious), structural details--4 valves, as opposed to six in Ensifera (see Tree of Life)
auditory organ (tympanum) if present, is on the abdomen (typically on front tibiae in Ensifera)
stridulation (if performed) typically accomplished by rubbing serration of inner surface of hind femur across veins of front wing--mechanism typically involves just the forewings in Ensifera

Food Feed almost exclusively on plants, though some will scavenge dead plant and animal material at times.
Remarks The fungus Entomophaga grylli attacks grasshoppers and is used as a biocontrol Cornell University.
