Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF                                                                                 
Adult Markings: Rhopobota finitimana resembles R. dietziana, but differs in having a solid basal patch and a brown head and scape. Instead of a basal patch, R. dietziana has basal and sub-basal fasciae that are separated by light scales which produces a narrow dark band. R. dietziana also has whitish coloration on the scape and head.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larvae mine the leaves of several species of holly. The mine characteristics vary depending on the host plant. Ken Kneidel recently reared two adults from mines on American Holly. When using this species the larvae live in linear mines that begin at the midrib and develop numerous lateral branches that make them strongly digitate. Frass is expelled at an opening near the midrib.

Larvae that were maintained in captivity eventually evacuated the mines and pupated within a silk covering that was constructed in folds of leaves, on paper tissue, or on a plastic bag. The adults emerged in less than two weeks after pupating when kept at room temperature. When using other hollies such as Ilex decidua, the mines tend to be less complex and generally shorter and wider with less conspicuous digitate patterning (Eiseman 2019). Larvae that were reared by Eiseman (2019) pupated beneath a cut and folded leaf margin. Populations that use American Holly probably also use a portion of a folded leaf to pupate, but field observations are needed to confirm this.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.

Habitats and Life History
Habitats: In North Carolina, records come from a Piedmont stand of mesic hardwoods.
Larval Host Plants: Larvae feed on Ilex species, including I. mucronatus and verticillata (Brown et al., 2008). In North Carolina, it has been reared on Ilex decidua (T. Feldman, BugGuide, accessed 2019-12-30).
