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.

TL 2.5-2.6, HL 0.70-0.76, HW 0.48-0.54, CI 67-71, ML 0.40-0.42, MI 55-57, SL 0.48-0.52, SI 96-100, PW 0.27-0.28, AL 0.67-0.72 (5 measured).

Characters of the mayri-complex. Preapical tooth spiniform, longer than maximum width of mandible. Dorsolateral margin of head with a single freely laterally projecting simple hair, the apicoscrobal. Cephalic dorsum with 4-6 erect simple hairs along the occipital margin and a similar pair at level of highest point of vertex. Preocular notch strongly present; ventral surface of head with a preocular transverse impression posterior to the deeply incised postbuccal groove. Pronotal humeral hair simple, pronotum otherwise without erect hairs; mesonotum with one pair of erect simple hairs. Dorsal alitrunk evenly reticulate-punctate. Dorsal surfaces of waist segments and first gastral tergite with simple hairs. Side of alitrunk reticulate-punctate except for katepisternum which has a small smooth patch. Propodeum armed with a pair of long slender needle-like spines that are elevated at about 45°; length of spine greater than dorsal width of petiole node, approaching width of disc of postpetiole. Dorsal (outer) surface of hind basitarsus without long fine erect hairs. Petiole in profile with anterior face of node equal to or slightly greater than length of dorsum, in dorsal view petiole node approximately as broad as long. Disc of postpetiole finely reticulate-punctate.
