Cameraria ostryarella
(Chambers, 1871)
Hophornbeam Blotchminer
Cameraria ostryarella is a small leaf-mining in the Gracillariidae. The is restricted to eastern North America, where its larvae feed exclusively on hophornbeam (Ostrya) species. Larvae create blotch mines in leaves, giving the species its . are tiny, with a wingspan of only 6–7 mm.

Identification
The combination of extremely small size (6–7 mm wingspan), association with Ostrya plants, and the distinctive blotch-shaped leaf mines of the larvae help distinguish this . may require dissection or molecular analysis for definitive identification from other Cameraria species.
Appearance
are minute with a wingspan of 6–7 mm. Wing patterns and body coloration are typical of the Cameraria, though specific markings are not well documented in available sources.
Habitat
Found in deciduous forests and woodlands where hophornbeam (Ostrya) trees occur. The presence of plants is the primary requirement.
Distribution
Eastern North America: Canada (Ontario, Quebec) and United States (Illinois, Kentucky, Maine, Michigan, New York, Connecticut, Vermont).
Diet
Larvae feed on Ostrya , specifically Ostrya virginiana (American hophornbeam) and Ostrya virginica. They mine the leaves of their plant, creating internal feeding tunnels.
Host Associations
- Ostrya virginiana - larval American hophornbeam
- Ostrya virginica - larval
Life Cycle
Larvae are leaf miners, feeding internally within Ostrya leaves. Specific details regarding site, number of per year, and stage are not documented in available sources.
Behavior
Larvae create blotch mines—irregular, expanded feeding areas within leaf tissue. This mining is characteristic of the and distinguishes them from external feeders.
Ecological Role
As a herbivore, the contributes to leaf damage on Ostrya trees. The ecological impact is likely minor given the restricted range and localized distribution. Leaf mining may provide entry points for secondary , though this has not been documented.
Human Relevance
No significant economic or health impacts. Occasionally encountered by botanists and entomologists surveying for leaf miners. The 'Hophornbeam Blotchminer' reflects its use as an indicator of plant presence.
Similar Taxa
- Other Cameraria speciesMany Cameraria are morphologically similar and require plant association or genitalia examination for separation. C. ostryarella is distinguished by its exclusive use of Ostrya hosts.
- Phyllonorycter speciesOther Gracillariidae also create leaf mines, but typically produce serpentine or tentiform mines rather than the blotch mines characteristic of Cameraria.

Original description
First described as Lithocolletis ostryarella by Chambers in 1871, later transferred to Cameraria.
Nomenclatural note
The epithet 'ostryarella' derives from the Ostrya, reflecting the close association between this and its hophornbeam hosts.
