Euzophera magnolialis
Capps, 1964
magnolia root borer
Euzophera magnolialis is a described by Capps in 1964, restricted to the southern United States. Its , magnolia root borer, reflects its specialized larval habit of boring into the roots of Magnolia grandiflora. The has a wingspan of 34–41 mm. It is one of approximately 50 species in the Euzophera, a group of small whose typically feed internally in tissues.

Identification
The combination of moderate size (wingspan 34–41 mm), southern U.S. distribution, and association with Magnolia grandiflora may help distinguish this from other Euzophera. Euzophera semifuneralis, the plum borer, is a related species that feeds beneath bark of trees rather than in roots, and is not restricted to magnolia.
Appearance
have a wingspan of 34–41 mm. As a member of , it possesses the characteristic snout-like projection formed by elongated labial . Specific coloration and pattern details are not documented in available sources.
Habitat
Associated with Magnolia grandiflora (southern magnolia) in the southern United States. The larval consists of the root systems of this tree.
Distribution
Southern United States.
Diet
feed on Magnolia grandiflora. likely do not feed, as is typical for many , though this has not been explicitly documented.
Host Associations
- Magnolia grandiflora - larval bore into roots
Life Cycle
bore into the roots of Magnolia grandiflora. Details of placement, site, number of per year, and stage are not documented.
Behavior
exhibit root-boring , tunneling within the root tissue of their . behavior has not been described.
Ecological Role
As a root-boring , may influence tree health and nutrient allocation in Magnolia grandiflora. The serves as a potential for ; Mesostenus gracilis has been documented parasitizing related Euzophera semifuneralis.
Human Relevance
The suggests potential significance as a pest of ornamental southern magnolia, though specific economic impact has not been quantified. May be encountered by studying root-boring or magnolia-associated .
Similar Taxa
- Euzophera semifuneralisBoth are North Euzophera , but E. semifuneralis feeds beneath bark of trees (including plum, peach, and others) rather than in magnolia roots, and has a broader host range and distribution.

Taxonomic history
Described by Hahn William Capps in 1964, with the specific epithet magnolialis directly referencing its magnolia association.
Observation status
Only two observations recorded in iNaturalist as of source date, suggesting it is rarely encountered or underreported, possibly due to its subterranean larval habit.
