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 2.0, HL 0.54, HW 0.44, CI 81, ML 0.20, MI 37, SL 0.28, SI 64, PW 0.25, AL 0.54. Preapical tooth only fractionally shorter than width of mandible at point where it arises, but obviously shorter than maximum width of mandible. Broadest point of mandible in full-face view just proximal of preapical tooth; inner margin shallowly concave from broadest point to base of apicodorsal tooth. Scrobe in profile broad dorsoventrally, deeply concave and with sharply defined margins. Upper scrobe margin in full-face view with a fringe of anteriorly curved fine short hairs; without elongate freely projecting hairs. Eye small, with about 6 ommatidia in total. Bullae of femoral glands present, small but distinct on each leg. Bullae of tibial glands small and inconspicuous on middle and hind legs but on foreleg very large and located on inner surface. Legs without standing hairs of any form on any surface. Propodeal teeth short, acutely triangular. Petiole node in dorsal view broader than long; in profile anterior face of node rounding broadly and evenly into dorsum, without a sharply defined anterodorsal angle. Head, alitrunk, waist segments and gaster blackish brown, appendages lighter.
