Formica aserva are a large parasitic variety of Formica which live in throughout Canada. They're have red head and thoraxes, with shint black abdomens. These are larger than most Formica with queens from 8-10 mm and workers from 6-10 mm. They grow large colonies up to 15,000 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. Note that this species requires good ventilation, or their formic acid spray may become an issue.
