About Arhaphe arguta (Bliven, 1956)
Arhaphe arguta (Bliven, 1956) measures approximately 9 to 10 mm in length. This species is active between April and October. Most adults are encountered in August and September, and larvae are also most commonly collected during these two months, with occasional collections in October. Observed individuals have been recorded running among dead leaves, on moist sand close to creek beds, and under vegetation such as Arctostaphylos pungens. When mating, pairs position themselves end-to-end, and they separate quickly if they are disturbed. Females of this species possess a sharp ovipositor, which is likely used to lay eggs in leaves or solid substrates. Arhaphe arguta is common in Arizona, where it is found especially in leaf litter, on bare ground, and under bear grass. Some individuals have been observed feeding on Bermuda grass. This species inhabits mountainous areas, specifically canyons that run along creeks, mountain saddles, and areas located near caves and dams.
