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 2.1, HL 0.54, HW 0.41, CI 76, ML 0.27, MI 50, SL 0.32, SI 78, PW 0.26, AL 0.58. Apicoscrobal hair present; upper scrobe margin without a similar hair at level of eye. Side of alitrunk with katepisternum entirely smooth, a smooth patch also present on metapleuron. Bullae of femoral glands inconspicuous and small, those on fore and hind femora of about equal size, slightly larger than those on middle femora. Basitarsus of hind leg with a single very long erect fine flagellate hair in the basal third of its dorsal (outer) surface; without a similar hair on dorsal (outer) surface of hind tibia. Propodeal teeth short and triangular. With petiole in profile height of anterior face of node less than length of dorsum of node, the two surfaces meeting through a broad even curve. Petiole node in dorsal view subglobular, only slightly broader than long. Basigastral costulae short, their length on the tergite distinctly greater than thickness of limbus but less than length of the postpetiole disc; the latter reticulate-punctate and may also have a few weak longitudinal costulae on the anterior half.
Paratypes. TL 2.1, HL 0.53-0.54, HW 0.39-0.40, CI 74-75, ML 0.26, MI 48-49, SL 0.30-0.32, SI 77-80, PW 0.24-0.26, AL 0.56 (2 measured).
