Known from a small number of collections from wet forest. One was a nest collection from a clay bank and another was made from the litter.

Strumigenys were once thought to be rare. The development and increased use of litter sampling methods has led to the discovery of a tremendous diversity of species. Many species are specialized predators (e.g. see Strumigenys membranifera and Strumigenys louisianae). Collembola (springtails) and other tiny soil arthropods are typically favored prey. Species with long linear mandibles employ trap-jaws to sieze their stalked prey (see Dacetine trap-jaws). Larvae feed directly on insect prey brought to them by workers. Trophallaxis is rarely practiced. Most species live in the soil, leaf litter, decaying wood or opportunistically move into inhabitable cavities on or under the soil. Colonies are small, typically less than 100 individuals but in some species many hundreds. Moist warm habitats and micro-habitats are preferred. A few better known tramp and otherwise widely ranging species tolerate drier conditions. Foraging is often in the leaf litter and humus. Workers of many species rarely venture above ground or into exposed, open areas. Individuals are typically small, slow moving and cryptic in coloration. When disturbed individuals freeze and remain motionless. Males are not known for a large majority of species.

Holotype. TL 2.2, HL 0.58, HW 0.47, CI 81, ML 0.16, MI 28, SL 0.30, SI 64, PW 0.26, AL 0.60. In full-face view with mandibles fully closed the length of the left preapical tooth is distinctly less than the distance between the base of the tooth and the base of the mandible. Leading edge of scape with fine projecting hairs, the longest of them slightly greater than the maximum width of the scape. Dorsolateral margin of head with abundant freely laterally projecting hairs that are fine, soft and relatively short, shallowly curved and shorter than the length of the scape. Erect hairs on cephalic dorsum and promesonotum fine and soft, relatively short but flexuous to sub flagellate. Clypeus with fine granular to punctulate sculpture, not as strongly sculptured as cephalic dorsum. Promesonotal dorsum finely densely punctulate everywhere.
Paratype. TL 2.1, HL 0.56, HW 0.44, CI 79, ML 0.14, MI 25, SL 0.28, SI 64, PW 0.24, AL 0.58.
Dimensions of non-paratypic workers. HL 0.58-0.60, HW 0.47-0.49, CI 80-82, ML 0.15-0.16, MI 25-27, SL 0.30-0.32, SI 63-67 (3 measured).
