Coptotriche clemensella
(Chambers, 1878)
Coptotriche clemensella is a of leaf-mining in the Tischeriidae. The species was described in 1878 by Vactor Tousey Chambers. Larvae create distinctive mines in the leaves of oak species, specifically Quercus macrocarpa, Quercus marilandica, and Quercus palustris. It has been recorded from four U.S. states in the central and eastern United States.

Identification
As a member of Tischeriidae, this likely exhibits the characteristics of small size and narrow, wings with reduced venation. Definitive identification requires examination of larval leaf mines on specific oak or genitalia. The mines are blotch-type, typically starting as linear and expanding into irregular blotches on the upper leaf surface.
Habitat
Associated with oak-dominated forests and woodlands where occur. Host oaks (Q. macrocarpa, Q. marilandica, Q. palustris) occupy varied from dry uplands to wet lowlands, suggesting the occurs across a range of oak woodland conditions.
Distribution
United States: Arkansas, Kentucky, Ohio, and Texas.
Diet
Larvae feed on Quercus macrocarpa (bur oak), Quercus marilandica (blackjack oak), and Quercus palustris (pin oak). diet unknown.
Host Associations
- Quercus macrocarpa - larval plantlarvae mine leaves
- Quercus marilandica - larval plantlarvae mine leaves
- Quercus palustris - larval plantlarvae mine leaves
Life Cycle
Larvae are leaf miners, feeding internally within oak leaf tissue. Specific details of , timing, and number of per year have not been documented.
Behavior
Larvae construct blotch mines in oak leaves, feeding between the upper and lower . Mining activity begins as a narrow gallery that expands into an irregular blotch, with typically deposited within the mine.
Ecological Role
As a , larvae contribute to herbivory pressure on oak foliage. The ecological impact on trees has not been quantified; damage is generally considered minor given the localized nature of individual mines.
Human Relevance
No known economic or conservation significance. Occasionally encountered by naturalists and entomologists examining oak leaf mines.
