Coptotriche consanguinea
(Braun, 1972)
Coptotriche consanguinea is a leaf-mining in the Tischeriidae, described by Annette Frances Braun in 1972. It is known only from California, where its larvae create mines in the leaves of several oak (Quercus). The species is one of relatively few documented members of its in western North America.

Identification
are small with narrow, wings typical of Tischeriidae. The Coptotriche can be distinguished from related genera by wing venation and genitalic characters; -level identification requires examination of genitalia. Larval mines appear as blotch or linear patterns on oak leaves, with the specific mine potentially aiding identification when association and location are considered.
Habitat
Associated with oak woodland and chaparral where oaks (Quercus dumosa, Q. garryana, Q. lobata, Q. turbinella) occur. These environments range from coastal sage scrub to interior oak savanna and foothill woodland in California.
Distribution
Known only from California, United States. Records are based on documented specimens and observations from locations where oaks are present.
Diet
Larvae feed on leaves of Quercus dumosa, Quercus garryana, Quercus lobata, and Quercus turbinella. They are leaf miners, feeding internally between the epidermal layers of leaves.
Host Associations
- Quercus dumosa - larval coastal sage scrub oak
- Quercus garryana - larval Oregon white oak
- Quercus lobata - larval valley oak
- Quercus turbinella - larval shrub live oak
Life Cycle
Complete with , larva, pupa, and stages. Larvae mine leaves of oaks; specific details of site and number of per year are not documented.
Behavior
Larvae are endophagous leaf miners, creating internal feeding galleries in oak leaves. are presumably or , as is typical for Tischeriidae.
Ecological Role
As a , larvae contribute to herbivory pressure on oak foliage. Their mines may increase leaf desiccation rates and could serve as microhabitats for other organisms, though specific ecological impacts are unstudied.
Human Relevance
No documented economic or cultural significance. The is of potential interest to lepidopterists and researchers studying oak-associated insect .
Similar Taxa
- Other Coptotriche speciesMultiple occur in North America; genitalic examination is required for definitive identification. Some share oak , complicating field identification.
- Other Tischeriidae leaf minersSeveral in Tischeriidae mine oak leaves; mine and specificity may help distinguish them, but identification requires microscopic examination.

Taxonomic note
Described by Annette Frances Braun, a prolific American lepidopterist who described numerous microlepidoptera in the 20th century. The specific epithet 'consanguinea' (Latin for 'related' or 'kindred') may refer to similarity to related species.
Research status
