Nothing is known about the biology of Strumigenys decipula.
Bolton (2000) - A member of the gundlachi complex in the Strumigenys gundlachi group. Very closely related to Strumigenys subedentata (see there) but immediately differentiated by its lack of standing hairs on the dorsal alitrunk, very broad scape and smaller eyes.

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 0.57, HW 0.48, CI 84, ML 0.25, MI 44, SL 0.22, SI 46, PW 0.32, AL 0.56. Characters of gundlachi complex. Inner margins of mandibles strongly convex in full-face view, at full closure touching at about the midlength and diverging both proximally and distally. Apex of mandible with 2 minute intercalary denticles between apicodorsal and apicoventral teeth. Preapical denticles restricted to distal third or less of mandible, 4 - 5 in n umber and minute; distal most denticle the largest, located very close to the apicodorsal tooth and separated from the remaining 3 - 4 denticles by a short diastema. Scape short and very broad, its anterior margin expanded forward into a large convex lobe; SL only 2.75 X the maximum scape width. Eye small, with only 3 ommatidia in the longest row. Apicoscrobal hair short. Pronotal humeral hair short, very broad, flat and leaf-like. Dorsal surfaces of head and alitrunk with dense short spatulate ground-pilosity that is decumbent to appressed, but without standing hairs of any form.
PARATYPE. TL 2.1-2.2, HL 0.56-0.58, HW 0.48-0.49, CI 83-88, ML 0.24 - 0.26, MI 43-45, SL 0.22-0.26, SI 46-54, PW 0.31-0.34, AL 0.56 - 0.58 (8 measured).
