Description of adults

 

Tomato-potato psyllid (Bactericera cockerelli)Adult tomato-potato psyllids measure 1.3 – 1.9 mm in length (2.8 – 3.2 mm including the forewings). 

When freshly moulted the body is initially pale  green or light amber but soon darkens to mainly brown or almost black. 

The head and body have distinctive whitish markings which vary in size and intensity. 

The antennae have a striped appearance due to the lighter colouration of the basal two-thirds of segments 3- 8.

More details on the diagnostic characters of adult TPP are given in the key.
