Identification

Larvae create distinctive blotch mines in hawthorn leaves, which may help distinguish this from other leaf-mining insects. are typical small in the Tenthredinidae. Specific diagnostic features for separating P. canadensis from are not well documented in available sources.

Habitat

Associated with hawthorn (Crataegus) plants; likely occurs in woodland edges, hedgerows, and other where hawthorn grows.

Distribution

North America; specific range details beyond continental occurrence are not well documented.

Diet

Host Associations

  • Crataegus - larval Larvae mine leaves of hawthorn

Ecological Role

As a leaf-miner, larvae modify hawthorn leaf tissue. The ecological significance of this interaction is not well studied.

Human Relevance

May be of minor interest to horticulturists managing hawthorn plantings, though not considered a significant pest.
