Cameraria aceriella

Description

The maple leafblotch miner (Cameraria aceriella) is a moth of the family Gracillariidae. It is known from Quebec, Canada and Connecticut, Illinois, Kentucky, Pennsylvania, Wisconsin, Maine, Maryland, Michigan, New York and Vermont in the United States. The wingspan is 8–9 mm. Adults are on wing from the end of May to June. The larvae feed on Acer species, including Acer rubrum and Acer saccharinum. They mine the leaves of their host plant. They mine into the parenchyma, just under the upper surface of the leaf. Later, they wrap silk around part of their mines to pupate. Part of the population overwinters in the larval form inside leaves that have fallen to the ground and pupate the following spring. The other part overwinters as pupae.
