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 3.4, HL 0.89, HW 0.61, CI 69, ML 0.44, MI 49, SL 0.51, SI 84, PW 0.36, AL 0.90. Mandible with a triangular preapical tooth. Dorsolateral margin of head in full-face view with 3 freely laterally projecting fine hairs: one at level of eye, one just posterior to level of eye and one in apicoscrobal position. Cephalic dorsum with a row of 4-6 erect fine hairs along the occipital margin and with 1-2 shorter erect hairs on lateral margin of occipital lobe; without erect hairs at highest point of vertex. Dorsum of head predominantly reticulate-punctate, overlaid by very fine irregular rugulae. Apical funicular segment spindle-shaped and constricted basally. Promesonotal dorsum and side of pronotum sharply closely punctate; katepistemum mostly smooth. Metapleuron and side of propodeum punctate but glossy. Anterior coxae with weak transverse rugulae or costulae. Pronotal humeral hair long and fine, curved/sinuate but not flagellate. Pronotal dorsum with 2-3 pairs of erect fine hairs, mesonotum with 3-4 similar pairs. First gastral tergite with long fine curved filiform hairs. Dorsal surface of hind femur without standing hairs; ventral surface with a spaced row of suberect hairs that are directed ventrolaterally. Dorsal (outer) surfaces of hind tibia and basitarsus each with 1-2 long erect freely projecting hairs. Propodeal teeth short, triangular and acute. Petiole in profile claviform.
