The oak leaf phylloxera, Phylloxera glabra (Heyden), is a small yellow-to orange aphid-like insect that causes chronic mid-summer scorching, defoliation, and ultimately death of severely affected Garry oak, Quercus garryana. This leaflet covers hosts, distribution, description, life history and habits, damage, and management options.
