Caloptilia fraxinella
Ash Leaf Cone Roller, Ash Leaf Cone Roller Moth
Caloptilia fraxinella is a leaf-mining moth in the family Gracillariidae. Native to North America, it has become a significant pest of horticultural ash trees (Fraxinus spp.) in Canadian Prairie cities and parts of the United States. The species exhibits an unusual life history with a 9-month adult reproductive diapause; adults eclose in summer, overwinter, and mate the following spring. Larvae mine ash leaves and eventually roll leaflets into cones for pupation.
Caloptilia undescribed-rhus
An undescribed species in the genus Caloptilia, recognized as a leaf blotch miner moth associated with Rhus (sumac) host plants. As a member of the Gracillariidae family, it exhibits the characteristic larval behavior of creating blotch mines within leaf tissue. The species remains formally undescribed in scientific literature, known primarily from observations and informal documentation.
Caloptilia undescribed-ribes
An undescribed species of leaf blotch miner moth in the genus Caloptilia, known to feed on currants and gooseberries (Ribes). This species belongs to a large genus of small moths whose larvae create distinctive blotch mines in leaves. The specific epithet 'undescribed-ribes' indicates its host plant association prior to formal scientific description.
