Silky Carpenter Ant
Camponotus sericeiventris
Fine golden hairs lie flat over the abdomen of this large black ant, found from Mexico to northern Argentina, and flash in sunlight as it runs over bark. Workers of one colony come in a continuous range of sizes, from slim minors to big-headed majors. As in other carpenter ants, the majors are thought to do most of the guarding and the cutting up of large prey.

Introduction to Silky Carpenter Ant
Fine golden hairs lie flat over the abdomen of this large black ant, found from Mexico to northern Argentina, and flash in sunlight as it runs over bark. Workers of one colony come in a continuous range of sizes, from slim minors to big-headed majors. As in other carpenter ants, the majors are thought to do most of the guarding and the cutting up of large prey.
How to identify a Silky Carpenter Ant
- Head and thorax are black and duller than the abdomen
- Front corners of the thorax form sharp, angular shoulders
- Largest workers are well over a centimetre long, with broad heads
- Single narrow waist segment between thorax and abdomen
Why Silky Carpenter Ant are interesting
- Like other carpenter ants it has no sting, and defends itself by biting and spraying formic acid from the tip of the abdomen.
- The name sericeiventris means silky belly, from the Latin words for silken and belly, after the golden hairs on the abdomen.
- Its larvae spin silk cocoons before pupating, as in most other ants of its subfamily, the Formicinae.
- Workers often travel along regular trails on trunks and branches between the nest and trees where they collect honeydew.

Adaptations and biological abilities
03
Why does Silky Carpenter Ant behave this way?
- Head and thorax are black and duller than the abdomen
- Front corners of the thorax form sharp, angular shoulders
- Largest workers are well over a centimetre long, with broad heads
- Single narrow waist segment between thorax and abdomen
Workers forage by day, with traffic on the trunk heaviest in the warm hours. At night most withdraw into the nest galleries, where the brood is tended at all hours.
04
Why Tropical forest?
Habitat: Tropical forest, forest edge and wooded savanna from the lowlands into the foothills. Colonies occupy cavities in the trunks and thick branches of living or dead trees, and workers forage over bark, foliage and the ground nearby.
Native range: North America, South America
Native range
Natural range, not this specific capture location.
Tropical forest, forest edge and wooded savanna from the lowlands into the foothills. Colonies occupy cavities in the trunks and thick branches of living or dead trees, and workers forage over bark, foliage and the ground nearby.
05
Why this diet?
Omnivorous. Workers collect honeydew from treehoppers and other sap-sucking bugs, drink nectar from glands on leaves and stems, and hunt or scavenge insects. Liquid food is carried home in the crop and shared mouth to mouth.
06
Activity, rest, and lifespan
Workers forage by day, with traffic on the trunk heaviest in the warm hours. At night most withdraw into the nest galleries, where the brood is tended at all hours.
No figures are published for this species. In carpenter ants generally, workers live for some months and queens for several years, in some species more than ten.
07
Silky Carpenter Ant reproduction
As in other carpenter ants, a mated queen is thought to shed her wings, seal herself in a cavity and rear the first workers from her own reserves. Eggs pass through grub and cocooned pupa stages. Later the colony raises winged queens and males, which leave on mating flights.
Workers are wingless females. Queens are larger, with a bulkier thorax, and bear wings until mating. Males are winged, slimmer and smaller-headed than queens, and appear only at mating time.

Where to find them
Where to find Silky Carpenter Ant
To find Silky Carpenter Ant in the wild, focus on the exact habitat patches that match its body design and daily behavior, not just the broad country where it exists. You usually do better by working one good piece of habitat inside north America, South America than by covering too much ground.
- Forest edge, canopy gaps, fruiting trees, or shaded trails where cover and food meet
- Sunlit logs, exposed branches, warm rocks, or regular perch sites used for scanning
- Protected habitat blocks within north America, South America
