Nothing is known about the biology of Strumigenys baladria.
Identification
Bolton (2000) - A member of the ebbae complex in the Strumigenys koningsbergeri-group. The huge bullae of the femoral and tibial glands render baladria immediately recognisable. The gland bullae here are similar in size to those of seynoka of the koningsbergeri-complex, enormously larger than in any other species of the ebbae-complex.

Description
Worker
Holotype. TL 2.8, HL 0.79, HW 0.65, CI 82, ML 0.34, MI 43, SL 0.43, SI 66, PW 0.35, AL 0.75. With characters of ebbae-complex. Preapical tooth short conical, its length less than half width of mandible at point where it arises. Inner margin of mandible weakly sinuate proximal of preapical tooth, sharp-edged and carina-like but without a prominent translucent lamella. Preocular concavity in ventrolateral margin of head conspicuous. Upper scrobe margins evenly divergent and shallowly convex from frontal lobes posteriorly; eye almost entirely invisible in full-face view. Vertex posteriorly with a broad but shallow and poorly defined transverse depression. Dorsum of head in profile with short erect hairs along occipital margin, 1-2 on dorsum of occipital lobe and a single pair at highest point of vertex; without erect hairs anterior to this. Pronotum with a single pair of short standing hairs, close to anterodorsal margin. Mesonotum with a single pair of short erect hairs. Katepisternum smooth, metapleuron with a smooth patch. Bullae of femoral glands enormous on all legs, very long and broad; with hind leg in dorsal view maximum length of bulla about 0.44 X length of femur and its width about 0.60 X maximum width of femur. Bullae of glands on tibiae also disproportionately large. Lamella on propodeal declivity with posterior (free) margin shallowly concave to straight. Disc of postpetiole smooth. Standing hairs on first gastral tergite simple.
Paratypes. TL 2.8-2.9, HL 0.78-0.80, HW 0.64-0.65, CI 81-82, ML 0.34-0.36, MI 43-46, SL 0.40-0.42, SI 63-65, PW 0.33-0.36, AL 0.70-0.75 (2 measured).
