Formica neorufibarbis are a bit of a weird species to me. They're a bit nowhere, since they can be outcompeted by many species, but at the same time they're everywhere, since they've pretty much invaded the entire North American Continent. In fact, their range overlaps significantly with animals like the polar bear and the wolverine.
Formica neorufibarbis are grey and orange Formica which live in central and southern Canada. These are smaller than most Formica with queens from 8-10 mm and workers from 6-8mm. They grow large colonies up to 5000 workers in just 3 years. They prefer 22-26 Celsius and like around 50% humidity, though there is slight variation across species. They're more skittish than most ants, and so are of medium difficulty to start, but are extremely enthusiastic and fast growing once they break 50 workers. In the wild, Formica are some of the most dominant ants, hunting down other species and consuming large amounts of biomass. We get many of these each year, though the numbers are variable.
