Ash (Fraxinus)-Aphid


Leafcurl ash aphid (Prociphilus fraxinifolii)

Pest description and damage Leafcurl ash aphids cause significant curling and twisting of ash leaves which provide protection for the white waxy aphids inside. The consensus is that damage substantially disfigures leaves, but does no lasting damage as the leaves continue to photosynthesize sugars for the plant.
