Camponotus herculeanus (or Hercules ant) is a species of ant in the genus Camponotus, the carpenter ants, occurring in Northern Eurasia, from Norway to Eastern Siberia, and North America. First described as Formica herculeana by Linnaeus in 1758, the species was moved to Camponotus by Mayr in 1861.
The colony of Camponotus herculeanus consists of one or several wingless females (queens), some fertile males, and three castes of sterile workers, known as majors, intermediates, and minors, in decreasing order of size. The queens are large, about 15 mm (0.6 in) in length, and are blackish in colour. The males are a similar colour but about half the size of the queens. The workers usually have blackish heads and gasters, and dark reddish-brown mesosomas, petioles and legs. In majors, the scapes (the long segments of the antenna, before the elbow) are shorter than the length of the head; in intermediates they are about the same length, and in minors, they extend well beyond the back of the head. The head and the dorsal surfaces of the mesosoma and gaster of the largest majors are bristly.

Possible
About 20% of wildlife watchers report a Hercules Carpenter Ant sighting in Tatra National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 37th most-seen of the 142 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Hercules Carpenter Ant in Tatra National Park on a given day, against under 5% in September to April, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Hercules Carpenter Ant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 15 parks where we can rate Hercules Carpenter Ant sightings, Tatra National Park ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Kluane National Park (Canada, about 20%).
GBIF citizen-science records
It is estimated from how often the Hercules Carpenter Ant is recorded against all the insects logged in Tatra National Park (16 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.
