Gryllus veletis is commonly known as the spring field cricket. This solitary, aggressive, omnivorous, burrow-inhabiting species is the most widespread field cricket in North America. It is commonly confused with Gryllus pennsylvanicus (the fall field cricket), over much of the continent, but can be distinguished through examination of life history, ovipositor and behavioural differences. Predators of G. veletis include American toads, wild turkeys, red-tailed hawks, wolf spiders and red-backed salamanders.
This species was first described as Acheta veletis by Alexander and Bigelow with Piatt County, Illinois listed as the type locality. Gryllus is Greek and Latin for cricket, while veletis comes from the Latin word veles, velitis [sic], meaning light-armed footsoldier, skirmisher, or guerrilla forces, in reference to its aggressive behaviour as compared with G. pennsylvanicus. Alexander later stated that the spelling was modified to veletis to match the middle e in Acheta.
When first described, G. veletis was thought to be derived from G. pennsylvanicus via allochronic speciation. Subsequent genetic studies have instead found G. veletis to group with... Wikipedia →

Rare
Under 5% of wildlife watchers report a Spring Field Cricket sighting in Toronto on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 1005th most-seen of the 1689 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Spring Field Cricket in Toronto on a given day, so our monthly data shows no clear season.
Among the best
Of the 4 cities where we can rate Spring Field Cricket sightings, Toronto ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Boston (United States, under 5%) and Montreal (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Spring Field Cricket is recorded against all the insects logged in Toronto (11 verified sightings), 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.
