Biology

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 3.4, HL 0.92, HW 0.64, CI 70, ML 0.50, MI 54, SL 0.58, SI 91, PW 0.35, AL 0.97. Mandible with a small triangular preapical tooth in the distal quarter. In anterior view apical fork of mandible forming a V-shape or very narrow-based U-shape, the dorsal tooth distinctly longer than the ventral. Lateral spongiform lobe of petiole long, tapering anteriorly in dorsal view or in profile, but extending forward to the level of the spiracle on the peduncle. Postpetiole finely and densely reticulate-punctate. Dorsolateral margin of head with 5 or more long fine hairs and a number of shorter simple hairs that freely project laterally; apicoscrobal hair usually slightly longer than any of the other main projecting hairs, its length about 0.35 X SL. With head in profile no long erect hairs arise from the dorsum in front of the highest point of the vertex; a few long erect hairs arise between the highest point and the occipital margin, the longest of which is shorter than the maximum depth of the head capsule. Longest hairs on first gastral tergite slightly shorter than length of tergite from base of limbus to apex and slightly shorter than the maximum depth of the first gastral segment in profile.

Paratypes. TL 3.7, HL 0.98, HW 0.71, CI 72, ML 0.55, MI 55, SL 0.64, SI 90, PW 0.40, AL 1.06 (2 measured). Somewhat larger than holotype; one pale, lacking full adult colour.
