Biology

Expand Explore Overview of Strumigenys biology  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. ‎

Description

Worker

Holotype. TL 2.2, HL 0.61, HW 0.48, CI 79, ML 0.26, MI 43, SL 0.34, SI 71, PW 0.28, AL 0.60. With characters of ebbae-complex; answering the description of ebbae but differing as follows. Preapical tooth conical and shallowly recurved; length of preapical tooth about equal to the width of the mandible at point where it arises. Inner margin of mandible proximal of preapical tooth very shallowly convex. Part of outer arc of eye visible in full-face view. Metapleuron and side of propodeum densely reticulate-punctate. Metanotal groove broadly impressed. Lamella on propodeal declivity very narrow, at maximum no broader than diameter of propodeal spiracle, its posterior (free) margin concave. Bullae of femoral glands small but distinct on middle and hind legs. Disc of postpetiole strongly reticulate-punctate.

Paratype. TL 2.1, HL 0.58, HW 0.47, CI 81, ML 0.25, MI 43, SL 0.34, SI 72, PW 0.27, AL 0.58.
