Ball, 1902
Scolops maculosus is a of planthopper in the Dictyopharidae, characterized by a distinctive elongated snout or 'horn' projection. It was described by Ball in 1902. Like other members of the Scolops, it is a small, squat insect feeding on plant sap. The species is known from arid regions of the southwestern United States.

Identification
Distinguished from other Scolops by specific characters of forewing venation and the configuration of spines on the hind tibia tip. The specific epithet 'maculosus' (spotted) may indicate a distinctive spotted or maculated pattern, though this requires verification. Species-level identification in Scolops generally requires examination of wing venation and hind tibial spine characters rather than coloration alone, as most species appear superficially similar.
Appearance
Small, squat planthopper approximately 5-8 millimeters in length. Body typically straw-colored, brown, or gray. Possesses a characteristic elongated snout or 'horn' projection extending from the , giving a Cyrano de Bergerac-like appearance. Wings may be long or short depending on form; wing venation of forewings is a key diagnostic character. Hind tibia bears spines at the tip, with number, length, and arrangement used to distinguish from similar . Nymphs produce waxy secretions from abdominal glands.
Habitat
Arid including dry fields, prairies, and grasslands. Occurs in regions with otherwise moist climates but favors dry microhabitats. Associated with plants in Asteraceae and Chenopodiaceae.
Distribution
Southwestern United States. Documented from Arizona, Colorado, New Mexico, and Texas.
Diet
Feeds on plant sap from plants. Not a pest of cultivated crops.
Host Associations
- Asteraceae - plant records compiled on University of Delaware website
- Chenopodiaceae - plant records compiled on University of Delaware website
Life Cycle
Fourth-instar nymphs produce wax from glands near the rear margin of abdominal segments, a trait shared with other Scolops . Waxy secretions likely function in deterrence or camouflage as plant debris.
Behavior
Capable of hopping to escape disturbance, which may complicate determination of actual plant associations. and nymphs found on vegetation.
Ecological Role
Phytophagous insect feeding on plant sap. Part of the planthopper in arid grassland . Prey for various ; nymphal wax secretions suggest anti-predator adaptations.
Human Relevance
Not a pest of agricultural crops. No significant economic impact documented.
