Common names for these insects include cave crickets, camel crickets, spider crickets (sometimes shortened to "criders" or "sprickets"), [2] and sand treaders. Those occurring in New Zealand are typically referred to as jumping or cave wētā . [ 3 ]
Oecanthus fultoni's common name of the thermometer cricket is derived from a relationship between the rate of its chirps and the temperature. An estimate of the temperature in Fahrenheit can be made by adding 40 to the number of chirps made in 15 seconds. [3] Before 1960, the name Oecanthus niveus was wrongly applied to this species. [4]
The Oecanthidae are a recently (2022 [1]) restored family of crickets based on the type genus Oecanthus Serville, 1831.They include "tree crickets", "anomalous crickets" and "bush crickets" (American usage) and can be found in warmer parts of most of the world (not the northern Palaearctic, Nearctic or Antarctica).
Tachycines asynamorus is a medium-sized, apterous camel cricket. Its body length ranges from 11.3–14.6 mm (0.4–0.6 in). It has very long antennae, palps, and cerci.The female has a long, gently upcurved ovipositor, 10.7–12 mm (0.4–0.5 in) in length.
Wētā is a loanword, from the Māori-language word wētā, which refers to this whole group of large insects; some types of wētā have a specific Māori name. [2] In New Zealand English, it is spelled either "weta" or "wētā", although the form with macrons is increasingly common in formal writing, as the Māori word weta (without macrons) instead means "filth or excrement".

Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae. They hatch in spring, and the young crickets (called nymphs) eat and grow rapidly. They shed their skin eight or more times before they become adults. Field crickets eat a broad range of food: seeds, plants, or insects (dead or alive).
The chirp (or trill) of a tree cricket is long and continuous and can sometimes be mistaken for the call of a cicada or certain species of frogs. While male tree crickets have the ability to call, females lack the ability. [5] This call is then received by other tree crickets in the area through a system called sender-receiver matching.
Math textbooks will sometimes cite this as a simple example of where mathematical models break down, because at temperatures outside of the range that crickets live in, the total of chirps is zero as the crickets are dead. You can apply algebra to the equation and see that according to the model at 1000 degrees Celsius (around 1800 degrees ...
