scientific name Prochoerodes lineola (Goeze)

common name Large Maple Spanworm

previous name(s) Prochoerodes transversata

habitat
Mixedwood and deciduous forests and woodlands.

seasonality
Late July into September in Alberta; peak flight in early August.

identification
A 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.

range
Widespread throughout the eastern half of the continent, north and west to Alberta and south to FL (McGuffin 1987).

notes
Synonym: Prochoerodes transversata (Drury)
