Acrocercops astericola
Aster Tentiform Blotchminer
Acrocercops astericola is a leaf-mining moth in the family Gracillariidae. The species is known from eastern North America, where larvae feed on asteraceous host plants. Adults are small moths typical of the microlepidoptera. The common name refers to the distinctive tentiform blotch mines created by larval feeding.
Macrosaccus morrisella
hog peanut moth, soybean tentiform leafminer
Macrosaccus morrisella is a small leaf-mining moth in the family Gracillariidae, native to North America. Historically associated with native legumes including American hogpeanut and slickseed fuzzybean, it has recently expanded its host range to include soybean, with first reports from Quebec in 2016 and Minnesota in 2021. The species is notable for its hypermetamorphic larvae that produce distinctive serpentine-to-blotch-to-tentiform leaf mines, and its emergence as a potential agricultural pest of a major commodity crop.
Phyllonorycter albanotella
Marginal Tentiform Oak Leafminer
Phyllonorycter albanotella is a minute moth in the family Gracillariidae, commonly known as the Marginal Tentiform Oak Leafminer. Adults have a wingspan of 6–7.5 mm. The species is specialized on oaks, with larvae creating distinctive tentiform mines on the undersides of leaves. It occurs in eastern North America from Ontario and Québec south to Texas.
Phyllonorycter basistrigella
Phyllonorycter basistrigella is a minute leaf-mining moth in the family Gracillariidae. The species creates distinctive tentiform mines on the undersides of oak leaves, with larvae constructing an oval frass ring around the pupal cocoon. It is widely distributed across eastern and western North America, with records from Canada and numerous U.S. states. The wingspan measures approximately 8 mm.
Phyllonorycter blancardella
spotted tentiform leafminer, apple leafminer moth
Phyllonorycter blancardella is a small leaf-mining moth in the family Gracillariidae, widely distributed across Europe and North America. The species is a significant pest of apple orchards, where larvae create distinctive spotted tentiform mines in leaves. Adults are tiny with variable forewing coloration, often orange or tawny with blackish scaling. The species has two to three generations per year in temperate regions and is subject to complex parasitoid communities that influence its population dynamics.
Phyllonorycter tritaenianella
A small North American leaf-mining moth in the family Gracillariidae. The species creates distinctive blotch mines on Ostrya species, with larvae developing through a flat blotch stage before the mine becomes tentiform as the leaf folds over. Adults are known from the northeastern United States and southeastern Canada.
