Taxonomy
Family: GracillariidaeSubfamily: GracillariinaeTribe: [gracillariini]P3 Number: 0.0 MONA Number: 718.02
Comments: The genus Marmara contains 19 described species from North America and numerous undescribed species. Most species are monophagous, and the mines have been found on over 80 North American plant genera that belong to 40 families (Eiseman et al., 2017). Given the small number of described species relative to the large number of hosts, there appear to be dozens of undescribed species in the US. Many of the species are difficult to rear and are only known from leaf or stem mines. North Carolina appears to have numerous undescribed species based on host preferences and mine characteristics, and Tracy Feldman has spearheaded efforts to document these within the state. We have included Marmara that we believe are probably undescribed species (ca. 30) and have listed these by their host plants. We encourage individuals to submit any leaf or stem mines that they find based on the plant hosts in order to better document the distribution and relative abundance of these forms in North Carolina.
Identification
Field Guide Descriptions: Online Resources: Technical Description, Immature Stages: Eiseman (2022)                                                                                 
Adult Markings: This appears to be undescribed leaf and stem miner of Common Sweetleaf (Symplocos tinctoria). As of 2024, the adults have not been reared and our only records are for leaf mines.
Immatures and Development: This species produces long, linear, narrow mines on the upper leaf surface of Common Sweetleaf. The convoluted mine typically begins on the leaf blade and commonly loops around to cross over older portions of the mine. The larva eventually mines along the petiole, then into the stem (Eiseman, 2022). The larvae presumably overwinter in the stems, with the adults emerging the following spring.
Larvae ID Requirements: Unmistakable and widely known.
Distribution in North Carolina
Distribution: This species has been documented in Louisiana, Mississippi, Florida, South Carolina and North Carolina. As of 2024, we have records from the Coastal Plain, Piedmont, and at lower-elevation sites along the the Blue Ridge escarpment.

Flight Dates:
 High Mountains (HM) ≥ 4,000 ft.
 Low Mountains (LM) < 4,000 ft.
 Piedmont (Pd)
 Coastal Plain (CP)

Flight Comments: The flight season is undocumented because of the lack of adult records.
Habitats and Life History
Habitats: The host plant can be found in a variety of habitats that range from sandy pinelands and dry ridges to bottomland forests and the margins of pocosins.
Larval Host Plants: The only known host is Common Sweetleaf (Symplocos tinctoria)
Observation Methods: The mines are easy to spot on the leaves of Common Sweetleaf, but the adults have yet to be reared.

Comment: On Symplocos tinctoria. The larva initially mines the epidermis, then moves into the major veins, then into the petiole and stem. Probably an undescribed species.
