Of Special Interest

Antenna (pl antennae) -- paired, flexible, segmented sensory appendages on the head of the tree cricket -- functioning primarily as an organ of touch. antennomeres

Antepenultimate -- ante- meaning before, pen- from the Latin paene meaning almost, and ultimate from the Latin ultimus meaning 'last canthus cercus exoskeleton'

Exoskeleton - outer shell/skin

Exuvia - term for exoskeleton once it has been shed

Family - a group of related insects  i.e.  Gryllidae

Flagellum -- a whip-like structure, in this case the long antenna.

Forewings - in tree crickets are called tegmina

Genus - a genus is a group of closely-related species,  presumbably descended from a single common ancestor.

Gradual metamorphosis is a type of simple metamorphosis. Immature insects, aka nymphs, resemble small adults and have wing buds. They live in the same habitat as the adults, and typically eat the same foods.

Hemolymph - Fluid in the bodies of some insects that is the equivalent of blood. Concentrations of hemolymph on tree crickets will often look white.

Instar - life stage of an arthropod after molting, and shedding of the exoskeleton. The instars are numbered--the first instar being the stage between hatching from the egg and before the first molt.  Tree crickets have:  1st, 2d, 3d, 4th, and 5th instars.

Macropterous - long-winged

Metatarsus - and tarsus -- limb parts

Mouthparts - insect mouthparts are paired appendages (except for the labrum) used to get, manipulate, and chew food. 
labium - a fused pair of appendages, (like a tree cricket lower lip)
labrum - the "upper lip". Not always considered to be a true mouthpart.                               mandible - the 'jaw' -- mostly used to cut and chew food.                                                   maxilla - used in a manner similar to mandibles, used for sensing and manipulating food.

Nymph - the immature stage (between egg and adult)

Occiput, (adjective occipital )- The back of the head, where it connects with the "neck"

Oviposit - from Latin ovum, egg, and ponere, to put, place.

Oviposition - the action (oviposit) or process (oviposition) of laying eggs.

Ovipositor - an appendage of the telum (last abdominal segment) through which the eggs are laid.

Pedicel -   a piece supporting an organ, or joining one organ to another, like a neck. The second segment of the antenna. From Latin pedis, a foot

Scape - the basal (nearest the head, i.e., first) segment of the antenna.  From Latin scapus, stem.

Species noun (used as singular and plural), adjective specific - usually defined as a group of organisms capable of interbreeding and producing fertile offspring.

Stridulate verb, noun stridulation, adjective stridulatory - sound production by rubbing together body parts. From Latin stridor grating, stridulus creaking, squeaking.

Stridulation is most often an advertisement of male insects, but it can also serve for other forms of intra-specific communication, or as a warning to, or defense against, predators. Tree cricket stridulations are produced by tiny teeth-like projections on the ( ) wing rubbing against a rough file-like structure on the ( ) wing. 

Subfamily - a taxon ranked between family and tribe, or genus, thus a major division of a family. Comprises a group of related tribes, or of related genera. i.e. Oecanthinae.

Taxon, plural taxa - a taxonomic unit - a name designating an organism or group of organisms. A taxon is assigned a rank and can be placed at any given level in a systematic hierarchy.

Tegmen, plural tegmina - the roof-shaped thickened fore-wings in Orthopterans.  These are the wings the male tree crickets raise to sing.

Teneral, also used as adjective - a tree cricket that has freshly-emerged from shedding its exoskeleton. Typically tenerals are soft-bodied and have pale coloration. From Latin tener, soft, young, tender.

Tribe - a taxon ranked between subfamily and genus, or between subfamily and subtribe.

Venation - the state of having veins, or the pattern of veins or vein-like structures within a larger entity
