Scythropia crataegella from the safety of a silken web they produce together; young larvae are leaf miners. The mainstay food is leaves of "Crataegus" (hawthorn), hence the species' name. But they have also been recorded from other Amygdaloideae, e.g. blackthorn ("Prunus spinosa") and other "Prunus" species, "Cotoneaster", as well as "Malus sylvestris" and "Pyrus" (pear). Scythropia crataegella Scythropia crataegella, the hawthorn moth, is a species of moth in the family Plutellidae from western Eurasia.

Prunus maximowiczii leaves of "P. maximowiczii" are green; and those from the fruit, a dark grey to green. Chemically, amygdalin and prunasin, the derivatives of which produce prussic acid as well as Genistein can be extracted from "P. maximowiczii". Prunus maximowiczii Prunus maximowiczii, known as Korean cherry, Korean mountain cherry, or Miyama cherry, is a small (about 7.5 m), fruiting cherry tree that can be found growing wild in northeastern Asia and Eurasia. The species was first described in 1857 by Franz Josef Ruprecht. It was treated in the genus "Cerasus" (now generally accepted as a subgenus of "Prunus") by Vladimir Leontyevich
