The ant that walks with its rear in the air
Crematogaster scutellaris is one of the most recognisable ants in Europe: its raised gaster (abdomen) is its signature. When it feels threatened, it lifts its gaster upward like a scorpion, ready to spray a defensive substance. Its bright brick-red and black colouring makes it very striking.
An arboreal species, it nests in dead wood, under cork-oak bark, and forages on trees to collect honeydew from aphids and scale insects.
Blow gently on an active colony: the workers immediately raise their gaster as an alert signal. It’s one of the most impressive visual displays of keeping Crematogaster.
Founding
Nuptial flight in autumn (September-October). Claustral founding, 6-10 weeks for the first workers.
Artificial habitat
Recreate its arboreal environment: a wooden nest (cork, cedar) or a plaster nest with decorative branches. The outworld can include vertical elements (branches, bark plates) to observe its climbing abilities.
Conditions
Warmth of 22-27°C, moderate humidity (40-60%), a short winter hibernation (3 months at 8-10°C, not too cold since it’s Mediterranean).
Cork bark plates for terrarium
To set up a Crematogaster nest close to its natural habitat on cork oaks.
