Aphalara itadori
Family: Psyllidae

Aphalara species have no genal cones and no pterostigma, and their general colouration includes shades of red and brown.

A. itadori
is a non-native species that is being introduced (2010) to the UK in order to combat Japanese Knotweed. Initial releases are in southern England, but there should be later controlled releases at other locations.
 Please inform us of any records so that its spread can be monitored.

It can be separated from other species by the solid band of colour in the apical third of the wing (in other species it is more obviously mottled), by the cellular appearance of the forewing at high magnification, by features of the genitalia, and by its association with Japanese Knotweed.

Length ~3 mm
Adult: All year?
