Litaneutria skinneri
Rehn, 1907
Skinner's Ground Mantis
Litaneutria skinneri is a small ground-dwelling native to the southwestern United States. Unlike most mantids that employ ambush from vegetation, this is , actively pursuing prey across open ground. It inhabits arid and semi-arid environments including desert and grassland . The species was described by Rehn in 1907 and remains relatively poorly studied compared to its L. minor.

Identification
Distinguished from the sympatric Yersiniops by its rounded (Yersiniops has pointed, 'horned' eye apices) and generally browner coloration (Yersiniops tends toward gray). Separated from L. minor by geographic range: L. skinneri is restricted to the southwestern U.S. (Arizona, New Mexico, Texas) and western Montana, while L. minor occurs broadly across the Great Plains and into southwestern Canada. L. skinneri is also distinguished from L. obscura, another southwestern , though specific diagnostic features between these two remain poorly documented in available sources.
Habitat
Desert and grassland in arid and semi-arid regions. Occurs in open, sparsely vegetated environments where hunting is advantageous.
Distribution
Southwestern United States: Arizona, New Mexico, and Texas. Also recorded from western and central Montana.
Behavior
that actively runs down prey rather than employing the ambush strategy typical of most mantids. Has been observed hopping over rocks and darting swiftly through sparse vegetation when pursuing prey or evading predators.
Ecological Role
Predatory insect in arid grassland and desert .
