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
Larvae feed on hawthorn (Crataegus) leaves, creating blotch mines. likely feed on nectar or pollen, though this has not been explicitly documented.
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.
