Camponotus largiceps (Carpenter Ant)

Meet Camponotus largiceps: Large-Headed Chinese Carpenter Ant!

Why Camponotus largiceps?

Camponotus largiceps is a polymorphic Chinese carpenter ant described by Wu and Wang (1989) from Hunan and Anhui. Shiny dark queens and brown-to-black workers with a broad head profile make a neat intermediate Asian Camponotus for keepers who can offer a mild cool winter rest.

South China forests and meadows

AntWiki lists the species from China only (type localities in Hunan and Anhui). Trade sheets add Henan and describe subtropical forest, meadows and cultivated ground, with soil nesting. Published field biology remains thin compared with better-known carpenters.

Colony:

• Type: Hobby sources list monogyne
• Founding: Claustral
• Mature size: Hobby estimate a few hundred workers (scientific ceiling unpublished)

Queen:

• Size: Hobby reports roughly 15-16 mm
• Colour: Shiny black; legs reddish brown; bulky thorax

Workers:

• Size: Hobby reports roughly 5-14 mm
• Polymorphic: Yes
• Colour: Head and thorax brown; gaster black

Development:

• Egg to adult worker: Not published for this species; related warm-temperate Camponotus often take several weeks to a couple of months (UNVERIFIED)

Housing:

• Nest: Soil nests in nature; ytong, plaster, acrylic or naturalistic soil setups
• Temperature: Hobby nest targets often 24-28°C; outworld warm
• Humidity: Nest moderate (hobby often 50-70%); outworld drier

Hibernation / Diapause:

• Notes: Hobby sheets recommend a cool winter rest of about 2-3 months around 15-18°C (unheated room). Match origin if known

Diet:

• Primary: Honey water plus insects (flies, small crickets)

Interaction:

• Sting: No (Formicinae)
• Bite: Yes; formic acid spray expected

Key Stats:

• Queen Size: Estimated: 15-16mm
• Worker Size: Estimated: 5-14mm (polymorphic continuum)
• Major Worker Size: Estimated: toward upper end, up to about 14mm
• Temperature: Estimated: 24-28°C (Nest)
• Humidity: Estimated: 50-70%
• Diet: Sugars & Insects
• Colony Size: Estimated: a few hundred mature workers
• Diapause: Estimated: cool winter rest about 2-3 months around 15-18°C (unheated room; hobby)

Ready for a Chinese carpenter?

Published husbandry is limited, so keep careful notes. Warm active season, sugars and protein, then a mild cool rest, mirror what successful keepers report for this scarce species.
