Crickets chirp at different rates depending on their species and the temperature of their environment. Most species chirp at higher rates the higher the temperature is (about 62 chirps a minute at 13 °C (55 °F) in one common species; each species has its own rate). The relationship between temperature and the rate of chirping is known as Dolbear's law. According to this law, counting the number of chirps produced in 14 seconds by the snowy tree cricket, common in the United States, and adding 40 will approximate the temperature in degrees Fahrenheit.
A match's statistics are summarised on a scorecard. Prior to the popularisation of scorecards, most scoring was done by men sitting on vantage points cuttings notches on tally sticks and runs were originally called notches. According to Rowland Bowen, the earliest known scorecard templates were introduced in 1776 by T. Pratt of Sevenoaks and soon came into general use. It is believed that scorecards were printed and sold at Lord's for the first time in 1846.
Cricket is a multi-faceted sport with multiple formats that can effectively be divided into first-class cricket, limited overs cricket and, historically, single wicket cricket. The highest standard is Test cricket (always written with a capital "T") which is in effect the international version of first-class cricket and is restricted to teams representing the twelve countries that are full members of the ICC (see above). Although the term "Test match" was not coined until much later, Test cricket is deemed to have begun with two matches between Australia and England in the 1876–77 Australian season; since 1882, most Test series between England and Australia have been played for a trophy known as The Ashes. The term "first-class", in general usage, is applied to top-level domestic cricket. Test matches are played over five days and first-class over three to four days; in all of these matches, the teams are allotted two innings each and the draw is a valid result.
Some species, such as the ground crickets (Nemobiinae), are wingless; others have small fore wings and no hind wings (Copholandrevus), others lack hind wings and have shortened fore wings in females only, while others are macropterous, with the hind wings longer than the fore wings. In Teleogryllus, the proportion of macropterous individuals varies from very low to 100%. Probably, most species with hind wings longer than fore wings engage in flight.
Women's cricket was first recorded in Surrey in 1745. International development began at the start of the 20th century and the first Test Match was played between Australia and England in December 1934. The following year, New Zealand women joined them, and in 2007 Netherlands women became the tenth women's Test nation when they made their debut against South Africa women. In 1958, the International Women's Cricket Council was founded (it merged with the ICC in 2005). In 1973, the first Cricket World Cup of any kind took place when a Women's World Cup was held in England. In 2005, the International Women's Cricket Council was merged with the International Cricket Council (ICC) to form one unified body to help manage and develop cricket. The ICC Women's Rankings were launched on 1 October 2015 covering all three formats of women's cricket. In October 2018 following the ICC's decision to award T20 International status to all members, the Women's rankings were split into separate ODI (for Full Members) and T20I lists.
The ICC also organises competitions that are for several countries at once, including the Cricket World Cup, ICC T20 World Cup and ICC Champions Trophy. A league competition for Test matches played as part of normal tours, the ICC World Test Championship, had been proposed several times, and its first instance began in 2019. A league competition for ODIs, the 2020–22 ICC Cricket World Cup Super League, is planned to begin in 2020. The ICC maintains Test rankings, ODI rankings and T20 rankings systems for the countries which play these forms of cricket.
Cricket flour may be used as an additive to consumer foods such as pasta, bread, crackers, and cookies. The cricket flour is being used in protein bars, pet foods, livestock feed, nutraceuticals, and other industrial uses. The United Nations says the use of insect protein, such as cricket flour, could be critical in feeding the growing population of the planet while being less damaging to the environment.
