Partridge Scolops
Scolops perdix, commonly known as the Partridge Scolops, is a planthopper in the Dictyopharidae. It is one of 32 recognized species in the Scolops, which is to North America. The species is characterized by its distinctive elongated rostrum that gives the appearance of a horn or nose. Like other Scolops, it is not considered an agricultural pest.

Identification
The combination of small size (5-8 mm), squat body form, and prominently elongated rostrum distinguishes Scolops perdix from most other planthoppers. -level identification within Scolops requires examination of forewing venation patterns and the specific arrangement of spines on the hind tibia tip. The 'Partridge Scolops' suggests possible association with partridge or appearance, though this is not explicitly documented.
Appearance
Small, squat planthopper measuring 5-8 millimeters in length. Body coloration is straw-colored, brown, or gray. Possesses a highly elongated, horn-like rostrum projecting forward from the . Wings may be long or short; some individuals exhibit a short-winged form. Hind tibia bears spines at the tip, with the number, length, and arrangement varying among .
Habitat
Arid and semi-arid environments including dry fields, prairies, and grasslands. Occurs in dry even within otherwise moist climatic regions.
Distribution
Recorded from Arizona, Colorado, Delaware, District of Columbia, and Chihuahua (Mexico). Distribution falls within the broader North American range of the Scolops, which extends from southern Canada through the United States to northern Mexico.
Diet
Feeds on plant sap. plant records indicate associations with Asteraceae and Chenopodiaceae, though specific host plants for S. perdix are not separately documented.
Host Associations
- Asteraceae - plant Based on -level records; specific for S. perdix not confirmed
- Chenopodiaceae - plant Based on -level records; specific for S. perdix not confirmed
Life Cycle
Fourth-instar nymphs of at least some Scolops produce wax from abdominal glands; this trait may apply to S. perdix but has not been specifically confirmed. Wax secretions are used for deterrence and camouflage as cottony plant debris.
Behavior
Capable of jumping to escape disturbance. This hopping can make it difficult to determine whether an individual is actively feeding on a plant or has simply landed there after escape .
Ecological Role
Phloem-feeding herbivore. Wax production by nymphs contributes to avoidance strategies. Not a significant agricultural pest.
Human Relevance
No economic importance; not a pest of crops. Occasionally encountered by entomologists and naturalists in field surveys.
