Gryllus bimaculatus is a species of cricket in the subfamily Gryllinae. Most commonly known as the two-spotted cricket, it has also been called the "African" or "Mediterranean field cricket", although its recorded distribution also includes much of Asia, including China and Indochina through to Borneo. It can be discriminated from other Gryllus species by the two dot-like marks on the base of its wings.
The species is popular for use as a food source for insectivorous animals like spiders and reptiles kept as pets or in zoos. They are easy to raise and do not require prolonged exposure to cold in order to complete their life cycle.
The first genome assembly of Gryllus bimaculatus was published in 2021, with a genome size of approximately 1.66 Gb and 17,871 annotated protein-coding genes. A chromosome-level genome assembly of Gryllus bimaculatus was published in 2026. The genome size is approximately 1.66 Gb, with most of the assembly anchored to 15 chromosomes. The assembly has a BUSCO completeness of 98.7%, and 14,457 protein-coding genes were predicted.
In the wild, male crickets do not tolerate one another and will fight until there is... Wikipedia →

With luck
About 10% of wildlife watchers report a Southern Field Cricket sighting in Doñana National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 58th most-seen of the 87 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
January–February and July
In those months about 20% of wildlife watchers report a Southern Field Cricket in Doñana National Park on a given day, against under 5% in April–June and August–December, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Southern Field Cricket sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 6 parks where we can rate Southern Field Cricket sightings, Doñana National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Sierra Nevada National Park (Spain, about 10%).
Same order: Orthoptera
The closest relatives of the Southern Field Cricket that you can see in Doñana National Park (order Orthoptera, Grasshoppers, Crickets, and Katydids) are Egyptian Bird Grasshopper (about 20%), Lamenting Grasshopper (about 10%) and Truxalis nasuta (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Field Cricket is recorded against all the insects logged in Doñana National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
