Nothing is known about the biology of Strumigenys anthocera.


Bolton (2000) - A member of the Strumigenys tococae-group. Like Strumigenys usbensis and Strumigenys fairchildi, anthocera has the first gastral tergite finely and densely sculptured everywhere. S. anthocera is the largest of the three and is unique in the group in having a simple apicoscrobal hair and a pair of standing hairs on the mesonotum. The other species lack projecting hairs at these locations. Spongiform tissue is better developed on the waist segments in anthocera than in usbensis or fairchildi; usbensis lacks spongiform tissue beneath the petiole, which is distinct in anthocera and fairchildi though broader in the former than in the latter. The spongiform lobes of the waist segments tend to be narrow and sublamellate in fairchildi but are thick and coarse in anthocera.

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.

Bolton (2000) - TL 4.2, HL 1.06, HW 0.77, CI 73, ML 0.64, MI 60, SL 0.72, SI 94, PW 0.49, AL 1.07. First gastral tergite finely and densely longitudinally striolate-costulate; without appressed spatulate hairs such as are present on the cephalic dorsum but with a few fine flagellate hairs. Maximum diameter of eye ca 0.15. Apicoscrobal hair simple. Mesonotum with a pair of short curved standing hairs. In profile declivity of propodeum with a pair of spines dorsally and a second pair basally, the two about the same length. Ventral surface of petiole with a continuous curtain of spongiform tissue that terminates in a thick spongiform pad posterolaterally.
