Aspen Leaf Blotch Miner

Host: Aspen

Management - How to control this insect

Leaf miner control (the use of insecticides) is usually not necessary on aspen or poplars.  The damage is aesthetic damage and generally does not cause branch dieback or tree failure.  Healthy plants can recover from heavy defoliation. Research shows that plants under environmental stress are more susceptible to leaf miner so keep plants in good health.
