Bland, 1863
Thorn-limb Borer
Saperda fayi is a of in the , described by Bland in 1863. It belongs to the Saperda, a group of -sized cerambycids commonly associated with . The species is known from Canada and the United States, with records from New Brunswick, Ontario, and Québec in Canada. Two infraspecific varieties have been described: var. shoemakeri and var. immaculipennis. As a member of the Lamiinae , it likely develops as a in living or recently dead woody tissue.

Identification
Saperda fayi can be distinguished from other Saperda by its specific combination of morphological features, though detailed diagnostic characters require examination of and literature. The Saperda is characterized by an elongate body form, typically extending beyond the body in males, and often patterned or marked . The two described varieties (shoemakeri and immaculipennis) differ in maculation patterns, with immaculipennis presumably showing reduced or absent elytral spots.

Habitat
Specific requirements for Saperda fayi are not well documented in available sources. As a member of the Saperda, it is likely associated with deciduous forest habitats where suitable larval plants occur.
Distribution
Canada (New Brunswick, Ontario, Québec) and the United States. GBIF records confirm presence in these Canadian provinces. The full extent of its U.S. distribution is not clearly documented in available sources, though the is referenced in entomological literature as occurring in North America broadly.
Life Cycle
As with other members of the , Saperda fayi undergoes with , larval, pupal, and stages. Larval development occurs within woody tissue of plants, though specific host associations for this have not been documented in available sources.
Ecological Role
As a wood-boring , Saperda fayi contributes to the decomposition of material and serves as a food source for . The is part of the fauna of northeastern North forests.
Human Relevance
Saperda fayi has limited documented human relevance. It is not known to be a significant pest of forestry or agriculture. The has been documented in entomological collections and was first recorded from Missouri by Paul Kaufman, representing a noteworthy distributional record that connected the author with this collector.
Similar Taxa
- Saperda carchariasSimilar size and general appearance; both are North Saperda with elongated bodies. S. carcharias is associated with willow and poplar, and differences in association and subtle morphological characters separate the two.
- Saperda perforataAnother North with overlapping distribution. S. perforata typically shows distinct elytral perforations or punctation patterns that differ from S. fayi.

Taxonomic history
Two varieties have been described: Saperda fayi var. shoemakeri by Davis in 1923, and Saperda fayi var. immaculipennis by Breuning in 1952. The status and validity of these infraspecific would require modern taxonomic revision to confirm.
Collector connection
The holds personal significance in entomological , as Paul Kaufman first brought specimens of Saperda fayi from Missouri to the author's attention—representing an important state record at the time and initiating a long-term professional relationship between the collector and the author.
