Baudier et al. (2015) studied thermal tolerances of a variety of army ant workers. Labidus spininodis was one of a number of army ant species sampled with a life history that includes both below and above ground activities.

Jack Longino: This species is morphologically nearly identical to Labidus praedator, differing only in the presence of a ventral petiolar spine. Its behavior and general habitat preferences also seem the same. Like L. praedator, it can be found in lowland wet forests, but reaches highest density at mid-elevation sites. Labidus spininodis is less often encountered than L. praedator, and I have a slight sense that L. spininodis prefers primary forest areas while L. praedator can be found abundantly in second growth.

Labidus spininodis has massive carpet raids, like L. praedator.

Males of L. spininodis (as Labidus curvipes) are not attracted to lights and are possibly diurnal. The ALAS project, a large-scale arthropod survey based at La Selva Biological Station, has collected four males. One was in a Malaise trap at La Selva. The other three were in one Malaise trap sample and two flight intercept trap samples from the 500m site on the Barva transect. No male has ever been captured in the extensive programs of blacklight sampling. In contrast, males of L. praedator occasionally occur in blacklight samples.

Taxonomic Notes

Jack Longino: By a process of elimination and geographic correspondence, Labidus curvipes, a species known only from males, must be the male of L. spininodis.
