Caconemobius fori is a small cricket, approximately 9 mm (0.35 in) in length. [2] It lacks wings but is capable of jumping significant distances when disturbed. This species is darkly colored with an overall shiny quality, causing them to blend in extremely well with the freshly solidified lava that makes up their habitat.
Gryllus campestris, the European field cricket or simply the field cricket in the British Isles, [2] is the type species of crickets in its genus and tribe Gryllini. These flightless dark colored insects are comparatively large; the males range from 19 to 23 mm and the females from 17 to 22 mm.

Like most cricket species, Teleogryllus oceanicus males produce a calling song to attract potential female mates. Crickets produce the sound of their calls using a "file-scraper" system where, as the male opens and closes its wings, a plectrum (scraper) located on the posterior side of the left wing is rubbed against a filed vein located on the right wing.

Gryllus pennsylvanicus is known as the fall field cricket. G. pennsylvanicus is common in southern Ontario, is widespread across much of North America [3] [4] and can be found even into parts of northern Mexico. It tends to be absent in most of the southwestern United States including southern California.
Unusually for insects in the grasshopper family, wood crickets survive for two years. [4] Being flightless, these crickets are limited in their dispersal abilities; males have been found to disperse over 55 m (180 ft) from the woodland edge but females and nymphs did not move nearly so far. [5] Dispersal along the edge of woodland is more possible.
A boa constrictor in the U.K. gave birth to 14 babies — without a mate. The process is called parthenogenesis, from the Greek words for “virgin” and “birth.”
