Archips
Leafroller moths
Archips is a of in the , Tortricinae. The genus includes economically significant whose roll or tie leaves together with , feeding within these shelters. Some species are major agricultural and forestry pests, with larvae feeding on a wide range of plants including trees and shrubs. The genus has been subject to taxonomic confusion, with misidentifications documented in regional faunistic records.
Identification
are recognized by their habit of rolling or folding leaves into shelters using , within which they feed. are -sized with typical bell-shaped resting posture and mottled or gray . -level identification requires examination of and often dissection; external alone is frequently insufficient for reliable determination.

Distribution
Widespread across the Holarctic region, with documented in North America, Europe, and Asia. Specific distribution varies by species; some have restricted ranges while others are broadly distributed.
Seasonality
