The wingspan is 1 - 1.3 cm.

Marmara arbutiella is a butterfly from the family of the Marmara arbutiella moths (Gracillariidae). The scientific name of the species was first validly published in 1904 by Busck.

Parornix betulae is a moth of the family Gracillariidae. It is known from all of Europe (except the Iberian Peninsula, the Balkan Peninsula and the Mediterranean islands), east to Korea. It was recently reported from Canada, with records from Québec, Ontario and British Columbia. The wingspan is 9–10 mm. The head is fuscous, more or less mixed with white. Palpi white, sometimes with dark fuscous subapical ring. Forewings are grey, irrorated with dark fuscous and white ; numerous costal strigulae, a spot in middle of disc and another posteriorly,and two dorsal spots white ; a blackish apical spot ; cilia with two dark fuscous lines, tips round apex white, beneath apex with a third dark fuscous line. Hindwings are grey.The larva is whitish green ; dorsal line dark green ; head brownish ; segment 2 with four black spots. Adults are on wing in May and August. The larvae feed on Betula alleghaniensis, Betula grossa, Betula humilis, Betula obscura, Betula papyrifera, Betula pendula, Betula pubescens, Betula nana and Betula utilis. They mine the leaves of their host plant. The mine starts as an inconspicuous lower surface corridor, mainly recognisable by its brown line of frass. In the next larval stage a lower-surface blotch is made, that soon develops into a tentiform mine. The frass is deposited in a clump in a corner of the mine. After leaving the mine the larva continues feeding in a downwards folded leaf margin, that is fixed with silk.

Adorned with wings that bear an intricate pattern resembling frosted glass, hazel slender is a master of disguise amongst foliage, the hues and shapes on its wings camouflaging it from predators. This creature undergoes a remarkable transformation from a leaf-mining larva, which exploits its green haven for sustenance, to an adult that participates in nocturnal pollination activities, contributing to the health of local flora.

Hawthorn slender is a remarkable leaf-miner during its larval stage, carving out serpentine tunnels beneath the surface of leaves, which eventually form a protective cocoon. As an adult, it emerges with delicate, highly iridescent wings that give off an opalescent sheen, a distinct adaptation to its environment, efficiently camouflaging it from predators amidst foliage and dappled sunlight.

The locust digitate leafminer (Parectopa robiniella) is a moth of the family Gracillariidae. It is native to North America, but was accidentally introduced to Italy, where it was first found in 1970. It has now been recorded from Italy, France, Germany, Slovenia, Croatia, Austria, Slovakia, Romania, Ukraine and Hungary. The wingspan is about 5 mm. The moth flies in two to three generations per year in Hungary. The larvae feed on Robinia species, including Robinia pseudoacacia. It mines the leaves of the host plant. The common name is derived from "digitate", referring to the "finger-like" excavations all around the margins of the central blotch of the mine.

The moths forewings are mainly dark-brown with a yellow band along the costal margin. The wingspan is 0.39–0.43 in and it flies from May to October depending on location and in Britain is double-brooded and sometimes there is a partial third brood. The larva initially forms a mine and later rolls the leaf downwards from the tip, forming a cone. When mature a pale-brown pupa is formed in a white, membranous silken cocoon spun beneath a leaf and the moths can mate a week later.

Caloptilia bimaculatella is a moth of the family Gracillariidae. It is known from Canada (Ontario and Québec) the United States (including Florida, Kentucky, Maine, Michigan, Missouri, New York, Vermont, Connecticut and West Virginia). The wingspan is 9–10 mm. The larvae feed on Acer rubrum. They mine the leaves of their host plant.
