Scotoleon yavapai
(Currie, 1903)
Scotoleon yavapai is a of antlion in the Myrmeleontidae, first described by Currie in 1903. The Scotoleon is distributed across North America, with characterized by cryptic coloration and slender, lacy wings. Males of this genus typically possess elongated with bracket-like claspers. Larvae of Scotoleon species are predatory, burying themselves just below the soil surface to ambush prey rather than constructing pit traps.

Identification
can be distinguished from damselflies by their short, thick, clubbed . Males of Scotoleon have notably elongated tipped with bracket-like claspers, a trait especially pronounced in this . Adults exhibit cryptic coloration with dark spots and speckles on wings that break up their outline when at rest. When alighting on vegetation, they align themselves seamlessly against the substrate, rendering them nearly invisible. Larvae lack the pit-building of Myrmeleon; instead, they bury themselves just below the soil surface with jaws agape to ambush passing prey.
Habitat
Larvae occur in dry, sandy or dusty soils where they can bury themselves for ambush . are found among tall grasses, particularly at dusk.
Distribution
Recorded from North America and Middle America. Specific locality data within these regions is limited in available sources.
Diet
Larvae are predatory on small insects and other . Prey is captured with hollow, hooked that inject paralyzing and digestive fluids, allowing of tissues.
Life Cycle
Larvae pupate inside silken capsules spun underground, with sand grains incorporated into the cocoon. emerge from these subterranean pupal chambers.
Behavior
Larvae are sit-and-wait that bury themselves just below the soil surface. fly clumsily and are most active at dusk. When landing on vegetation, adults exhibit remarkable by aligning their bodies flat against stems or twigs to become essentially invisible.
Ecological Role
Larval contributes to regulation of small soil-dwelling . may serve as prey for such as praying mantids.

- Damselflies (Odonata: Zygoptera) antlions superficially resemble damselflies in their slender bodies and lacy wings, but possess short, clubbed versus the long, thread-like antennae of damselflies; antlions also have different wing venation and resting posture.
