'''''Psylla''''' (from the Greek ''psulla'', meaning flea) is the type genus of sap-sucking insects in the family Psyllidae. There are at least 110 described species in ''Psylla''.<ref name=catlife/><ref name=gbif/><ref name=bugref/> Species within the genus feed on various host plants.

Some agricultural pests, previously placed here, are now in related genera, such as ''Cacopsylla'' (which includes at least two species harmful to fruit trees); other revised species names include the "Albizia fly" (''Acizzia jamatonica'', in the same family) and the laurel fly (''Trioza alacris'' in the family Triozidae).
