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 2.9, HL 0.78, HW 0.54, CI 69, ML 0.35, MI 45, SL 0.41, SI 76, PW 0.34, AL 0.80. Mandible with a small preapical tooth, located close to the apicodorsal tooth. Dorsolateral margin of head in full-face view with at 4-5 freely laterally projecting flagellate hairs: one at level of eye, one just behind level of eye, one in apicoscrobal position, 1-2 posterior to this. Cephalic dorsum with a transverse row of erect flagellate hairs along occipital margin but without erect hairs anterior to this. Dorsum of head finely and densely reticulate-rugulose, spaces between rugulae feebly punctate. Apical funicular segment moderately constricted basally. Pronotal dorsum and side irregularly, but predominantly longitudinally, finely rugulose. Katepisternum mostly smooth but remainder of side weakly punctulate and with vestiges of longitudinal costulae. Anterior coxae finely transversely costulate. Pronotal humeral hair flagellate and very long. Dorsal alitrunk with numerous erect flagellate hairs, at least 4 pairs present on mesonotum. First gastral tergite with numerous long fine flagellate hairs. Dorsal and ventral surfaces of hind femur with spaced rows of standing hairs; dorsal (outer) surfaces of hind tibia and basitarsus each with long erect freely projecting filiform or flagellate hairs. Propodeal teeth short, triangular and acute. Petiole in profile claviform.
Paratypes. TL 2.9-3.0, HL 0.78-0.79, HW 0.54-0.56, CI 69-71, ML 0.34-0.36, MI 43-46, SL 0.41-0.42, SI 73-78, PW 0.34-0.35, AL 0.80-0.85 (3 measured).
