|scientific name Liothrips russelli |
On the leaves of Parthenocissus quinquefolia (Virginia creeper) (Chiasson 1986).
Body varies from 1.7mm to 2.4mm in length and is mainly dark brown. The antennae are light brown to yellowish brown, the apices of the fore femora and tibiae are yellow, and the fore tarsi are yellowish to yellow. The head is somewhat longer than broad and ocelli are present though the fore ocellus may be reduced in brachypters. The postocular setae are moderate in size and pointed. Antennal segment 3 has 1 outer sense cone, and segment 4 has 1 inner and 1 outer sense cone. The mouth cone is pointed to almost blunt. The major setae on the prothorax are well developed and blunt to pointed. The metanotum is covered with weak, longitudinally oriented hexagonal reticulations and the fore tarsi lack teeth. Males are brachypterous, and females are brachypterous or macropterous. Macropterous specimens have wings that are colourless except for a brown area at the extreme base of the wing. The pelta is broadly triangular, the wing holding setae are not well developed in brachypters, and the tube is short (Stannard 1968).
Leaf feeder (Mound and Marullo 1996).
