Aristaea issikii is a species of moth of the family Gracillariidae. It is known from Honshū, Japan.[1]
The wingspan is 8.2–10.5 mm.
The larvae feed on Aster ageratoides. They mine the leaves of their host plant. There are four instars. In the second instar, the larva makes a large blotch-mine, which occupies an area between the middle vein and margin of leaf, sometimes almost the entire surface. The leaf tissues within the blotch-mine are nearly entirely consumed by the larva in its third and fourth instars. In fully matured condition, the mine becomes a tentiform-type, with irregular longitudinal wrinkles on both the lower and upper sides of the leaf. Pupation takes place inside a whitish, boat-shaped cocoon, which is usually located on the lower side of the same leaf or another one.[2]
