Camponotus castaneus, the red hazelnut carpenter ant, is a species of carpenter ant located in the eastern United States. It is a primarily orangish-red ant in the family Camponotus. Its workers are usually around 8-10 mm, and queens around 18-20 mm. As with most Camponotus species, C. castaneus has majors and super-majors, usually appearing in the second or third year of the colony's founding, majors are usually 10-14 mm, with super majors being around 13-17 mm. C. castaneus has a generalist diet, feeding on insects and carbohydrates such as honeydew, which is easily accessible. The ant has a smooth thorax and abdomen, with 1 node separating them.
Similar to other Camponotus, C. castaneus will go into a hibernation-like state during the winter, called diapause. Though, unlike other ants, they go into diapause very early, usually during the first cool days of fall, they stop foraging; this is usually the reason they are not seen during fall or winter. In some hot areas, such as Southern Florida, they still go through diapause during fall and winter, regardless of the temperatures.
Like all ants, C. castaneus has 4 life stages: egg, larva... Wikipedia →

Rare
Under 5% of wildlife watchers report a Chestnut Carpenter Ant sighting in Houston on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 580th most-seen of the 1057 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 Chestnut Carpenter Ant in Houston on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Chestnut Carpenter Ant sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5
Of the 5 cities where we can rate Chestnut Carpenter Ant sightings, Houston ranks 5th at under 5%. The best odds are in Washington (United States, about 10%), Baltimore (United States, about 10%) and Philadelphia (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Chestnut Carpenter Ant is recorded against all the insects logged in Houston (15 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.
