Formica pallidefulva are similar to your average Formica in Canada, but have a much lighter body and are less aggressive. These are large, brownish ants at queens from 8-12 mm and workers from 6-9mm. They grow large colonies up to 5000 workers in just 3 years. They prefer 22-26 Celsius and like around 50% humidity. They're more skittish than most ants, and so are of medium difficulty to start, but are extremely enthusiatic 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, though Formica pallidefulva seem more peaceful than other varieties. We get just a few of these each year, but nonetheless are a wonderful species.
