Common NameLarge Maple Spanworm SeasonalityLate July into September in Alberta; peak flight in early August. IdentificationA large ochre or yellowish fall-flying geometrid. Extremely variable markings and colouration, to the point where barely two individuals are alike. Ranges from pale tan and almost completely unmarked to ochre with heavy transverse lines and extensive dark mottling. Despite this variability, lineola can be separated from similar species by the PM line, which forms a sharp point near the forewing apex. In other species (Synaxis jubararia, Synaxis pallulata and Tetracis sp.), the PM line is straight near the wing apex.

Life History Much like the adult, larvae are extremely variable in colouration, and mimic twigs. Adults are nocturnal and come to light (McGuffin 1987). Conservation Not of concern. Diet Info
Larvae are polyphagous on deciduous and coniferous trees and shrubs. Favoured hosts include trembling aspen (Populus), balsam fir (Abies), white birch (Betula), willow (Salix) and balsam poplar (Populus) (Prentice 1963).
