Nothing is known about the biology of Tetramorium bequaerti.
Bolton (1980) - Of the four species of the bequaerti-complex, characterized by their possession of standing hairs on the scapes and tibiae, T. bequaerti is easily separated from the other three (Tetramorium bulawayense, Tetramorium hortorum, Tetramorium xuthum) by its larger size, short blunt pilosity, and especially by the presence in T. bequaerti of a prominent lobe or lug at the lower occipital corner, not seen in related species.

Bolton (1980) - TL 4.3-4.6, HL 0.98-1.05, HW 0.84-0.90, CI 85-87, SL 0.90-0.94, SI 104-106, PW 0.66-0.70, AL 1.28-1.32 (5 measured).
Mandibles strongly longitudinally striate. Anterior clypeal margin entire, without trace of a median notch. Median clypeal carina strongly developed. Frontal carinae short and vestigial, at most extending back to level of midlengths of eyes, generally shorter; frontal carinae always very fine, sometimes indistinct except for immediately behind the frontal lobes. Antennal scrobes absent. Scapes long, SI > 100. Eyes moderate, maximum diameter 0.21-0.24, about 0.23-0.26 x HW. With the head in profile the lower occipital corner strongly projecting into a blunt lobe or lug which at its apex is about as broad as the maximum eye diameter. Propodeum armed with a pair of elongate spines, the metapleural lobes broadly triangular, elongate and running roughly parallel to the propodeal spines, which are narrower. Petiole node in profile elongate, rectangular, the dorsal length greater than the height of the tergal portion. In dorsal view the node longer than broad. Dorsum of head feebly sculptured, usually only with a sparse superficial punctulation or granulation, sometimes also with a few weak longitudinal striae. Sides of head in front of and below eyes with fine rugular sculpture, reticulate in places. Dorsal alitrunk with fine, delicate longitudinal striae or rugulae and with a fine, fairly dense but superficial punctulate-granular groundsculpture. Petiole and postpetiole with same ground-sculpture as is seen on alitrunk but with a stronger rugular component also present which may form meshes on the sides and dorsum. First gastral tergite finely punctulate-shagreened everywhere. All surfaces of head and body and all surfaces of scapes, femora and tibiae with abundant short, blunt, erect to suberect stout hairs. Colour dull red.
