The maple leaf miner ( Ectoedemia sericopeza ) belongs to the family of dwarf leaf miners (Nepticulidae). In the literature it was therefore also previously referred to as Nepticula sericopeza . Stigmella sericopeza is also rarer today .
designation
Although it is only a dwarf leaf miner species, this moth bears the German name maple leaf miner, while the Caloptilia rufipennella , which belongs to the family of leaf miners, is only called the maple moth . The maple moth lives in rolled up leaves, the maple miner moth in the fruits.

- Ectoedemia louisella
Appearance
The head and body of the larva are light yellow. Adult animals are strongly patterned for their species. It is gray-white and has three black horizontal stripes on the forewings. The red tuft on the head is striking. The hind wings are gray. The wingspan is about 6–8 millimeters.
distribution
In Europe from Fennoscandinavia to the Pyrenees , Italy , Greece and from Great Britain to Russia and Ukraine , but quite rare in England and only widespread in the southeast. In North America only around Delaware (Massachusetts), Ontario and Quebec.
Occur
The flight time is in May and August, in two generations. The larval season is from May to mid-August, the second generation mines from September to May of the following year.
food
The larvae only eat Norway maple ( Acer platanoides ).
Way of life
The eggs of the first generation lie on the petiole in spring, those of the second generation on the wing of the seed in summer. The caterpillars mine their way through the wing to the actual seed. The larvae of the maple leaf miner develop in the maple's seed pods. The old larva finally leaves the chamber and hibernates in the web, which is replaced by a cocoon in spring. The mines of the first generation larvae consist of a short superficial corridor that leads to the seed, which is eaten up. Second generation larvae eat a short mine in the bark of the petioles and from there eat their way into a bud that is eaten from the inside out. The pupation of both generations takes place outside the feeding tunnels in cocoons.
Harmful effect
The infected seeds are no longer capable of germination, turn brown and die. A premature shedding of the maple seeds or a reduction in seed production can be consequences of the feeding. This species is not yet of forest significance in Germany.
