While S. louisianae is quite striking in morphology, its being overlooked has been attributed to its coloration, its small size (≈ 2-3 mm), and habit of thanatosis (Smith 1931, Van Pelt 1958). This species has been predominantly collected in forested systems, and nests are typically located in rotting logs and soils (Smith 1931, 1947; Van Pelt 1958; Brown and Wilson 1959). It is exclu-sively predacious and preferentially preys upon collembolans (Wilson 1953).Figure 1.

Abstract
We report the first known vouchered collection of Strumigenys louisianae 
(Hymenoptera: Formicidae) from Illinois. Two specimens were captured in pit-
fall traps during a field study at Fults Hill Prairie Nature Preserve in Monroe 
County.
