Scientific name:
(Hemiptera: Psyllidae)

Facts: Psyllids are sometimes called “jumping plant lice”, but they are not lice at all. Psyllids can carry several plant diseases and are therefore known as “vectors” (capable of transmitting a disease from one host to another). The pictured insect is an Asian citrus psyllid. Another species, the potato psyllid is the same species as the tomato psyllid, and we refer to either tomato psyllid or potato psyllid depending on which host plant it is infesting.
