Habits
They make their nests in old Protea flowers,[1] dead, hollow branches, and under tree bark, also making nests constructed of well-chewed vegetable matter with the consistency of papier-mâché. The outer walls of these nests are blackened by the salivary secretions, and are thin, with the interior divided into irregular, connected cells, like a coarse sponge. These more or less spherical nests, ranging in diameter from 10–30 cm, are built in a fork or among the branches, some of the branches passing through the nest.[2] Workers are glossy black and 3–5 mm long, and the larger queen is about 8 mm long, both having heart-shaped abdomens.
Defense
Pheromone alarms are common among the social Hymenoptera. Some of these have been chemically identified, but the number is still small compared with the large number of species making use of them. The ketone octan-3-one is seen as the major component of the pheromone complex secreted from the heads of C. peringueyi.[3]
The sting or venom gland of other ant species has evolved in C. peringueyi into a gland secreting a smelly and irritant fluid, which, together with the ant's painful bite, is a strong deterrent to predation or attack.

General
The genus of Crematogaster, created by Peter Wilhelm Lund in 1831 (Lettre sur les habitudes de quelques fourmis du Brésil, adressée a M. Audouin. Annales des Sciences Naturelles 23: 113-138) is diverse, widespread and abundant, distributed over tropical, subtropical and warm-temperate regions throughout the world. Greek: 'kremastos' + 'gaster' = 'suspended stomach', which would make the literal generic spelling 'Cremastogaster', but Lund set it as 'Crematogaster', which is preserved by priority.[9]
The
Trail-laying amongst cocktail ants involves shuffling their hind legs without touching of the soil with their abdomens, as is common with other ant species. This results in a setting of footprints for other foragers to follow. The hind leg's tendon to the claw is swollen where it passes through the tibia into a spindle-shaped reservoir containing the pheromone, an oil-like, relatively nonvolatile substance.[10]
