Nothing is known about the biology of Strumigenys lacacoca.
Identification
Bolton (2000) - A member of the Strumigenys emeryi-group. This is the only species in the group in which the two pairs of erect hairs on the cephalic dorsum are long fine and flagellate; in all other members of the group they are short, quite stout and stiff.

Description
Worker
Bolton (2000) - TL 3.0-3.3, HL 0.72-0.78, HW 0.50-0.53, CI 67-71, ML 0.45-0.48, MI 61-66, SL 0.50-0.55, SI 102-105, PW 0.30-0.34, AL 0.73-0.78 (3 measured).
Mandible without preapical dentition. All elongate hairs on head and body fine and flagellate, including the two pairs on the cephalic dorsum. Pronotal dorsum predominantly to entirely reticulate-punctate; a few feeble longitudinal rugulae may be present but if so are very obviously secondary to the reticulate-punctate component. Pleurae and side of propodeum smooth. Propodeal lamella broad, its posterior (free) margin approximately straight to convex; propodeal lacuna present on side of lamella. Disc of postpetiole smooth or at most with faint superficial sculpture; a few short costulae may arise from the anterior margin and one or two longer costulae may occur toward the side of the dorsum. Ventral surface of petiole with a fringe or curtain of spongiform tissue.
Type Material
Bolton (2000) - Holotype and paratype workers, PANAMA: Canal Zone, Rio Chinillo, 22.ii.1924 (T.E. Snyder) (National Museum of Natural History, Museum of Comparative Zoology) [examined].
