Taxonomy
Family: GracillariidaeSubfamily: GracillariinaeTribe: [gracillariini]P3 Number: 0.00 MONA Number: 718.24
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 apparently undescribed species specializes on passionflower leaves. At least one adult has been reared (see above), but has yet to be described in detail.
Immatures and Development: As of 2024, the larvae have only been found mining the leaves of Yellow Passionflower. The larva produces a highly convoluted, linear, epidermal mine that crosses over older portions of the mine repeatedly. The whitish mines are usually produced in the upper surface of a leaf, and rarely in the lower surface.
Distribution in North Carolina
Distribution: As of 2024, the mines have been found in Texas and North Carolina, with at least three records from Scotland County in the Coastal Plain.

Habitats and Life History
Habitats:
Larval Host Plants: The only known host as of 2024 is Yellow Passionflower (Passiflora lutea).
Observation Methods: We recommend searching for occupied mines on passionflowers during the spring and summer months. The adults should be reared, photographed and collected whenever possible.
