Psylloidea is a superfamily of true bugs, including the jumping plant lice and others which have recently been classified as distinct families.
The Superfamily Psylloidea is further organized into finer groupings including:
Psyllids or jumping plant lice are small plant-feeding insects that tend to be very host specific, i.e. they only feed on one plant species (monophagous) or feed on a few related plants (oligophagous). Together with aphids, phylloxerans, scale insects and whiteflies they form the group called Sternorrhyncha, which is considered to be the most "primitive" group within the true bugs (Hemiptera). They have traditionally been considered a single family, Psyllidae, but recent classifications divide the group into a total of seven families; the present restricted definition still includes more than 70 genera in the Psyllidae.

At least 561 species and subspecies belong to the Family Triozidae.
