Machimia tentoriferella

The specific name 'tentoriferella' and common name 'gold-striped leaftier moth' suggest diagnostic features: gold striping on wings and the larval behavior of tying or rolling leaves into tent-like structures. Distinguishing from congeners likely requires examination of genitalia or detailed wing pattern analysis; specific diagnostic characters for Machimia species separation are not documented in available sources.

Adults have a wingspan of 20–26 mm. The specific epithet 'gold-striped' refers to characteristic wing patterning, though detailed coloration descriptions are not provided in available sources.

Associated with deciduous forests and woodlands containing host trees, particularly Fraxinus (ash) species. Presence indicated by larval leaf-tying damage on host foliage.

Eastern North America: Nova Scotia to North Carolina and Tennessee, west to Mississippi and Iowa, north to Ontario. Records from Vermont confirmed.

Adults fly from September to October; timing varies by location. Larval stage presumably occurs during spring and summer preceding adult emergence.

Larvae feed on Fraxinus americana (white ash) and Fraxinus nigra (black ash) as primary hosts. Additional recorded food plants include birch (Betula), elm (Ulmus), maple (Acer), oak (Quercus), basswood (Tilia), butternut (Juglans cinerea), cherry (Prunus), beech (Fagus), hickory (Carya), balsam poplar (Populus balsamifera), chestnut (Castanea), hazel (Corylus), apple (Malus), lilac (Syringa), and dogwood (Cornus). The breadth of recorded hosts may reflect opportunistic feeding or misidentifications; Fraxinus species are the confirmed primary hosts.

Complete metamorphosis with larval, pupal, and adult stages. Larvae construct rolled or tied leaf enclosures for shelter and feeding. Pupation presumably occurs within these leaf structures or in leaf litter, though specific details are not documented. Adults emerge in autumn.

Larvae are leaf-tiers, rolling or tying leaves together to form tent-like shelters in which they feed and develop. This behavior is the source of both the common name and the specific epitymology.

Herbivore; larvae function as folivores on hardwood trees, potentially contributing to nutrient cycling through leaf damage and serving as prey for parasitoids and predators.

Not known to be of significant economic importance. The broad host range includes some ornamental and timber species, but damage levels are not documented as severe. May be of interest to lepidopterists and naturalists due to distinctive larval behavior.
