Amber Inclusion/ Jumping Plant Lice
 

Psyllids are commonly called jumping plant lice. They are small insects that feed on plants, usually only a single (monophagous) or related (oligophagous). Psyllids, along with coccids, whiteflies and aphids, form the insect group Stenorryncha. This group is believed to be the primal group of the true bug Order Hemiptera. They are least studied because these insects are not usually pests. Currently, the whole insect Family Psyllidae was classified further into six families.

The primitive Psyllids was believed to have fed mainly on gymnosperms and lycopods. Fossils of Psyllids have been found to date back before the angiosperms have evolved (Permian Period). The evolution of angiosperms during the Cretaceous Period spear marked the beginning of the massive morphological and metabolic evolution of various insects, mainly as a defense against insects that are herbivores.

Primitive insects were theorized to feed on dead or decaying animals (saprophagous) before shifting to become complex herbivores as their secondary adaptation. Plant resources, whether a single or related plant or from species to species, have varied allocation during different seasons. Insects have to adapt to the changes made by the plant. Once an insect has adapted to a plant species, it will not have any difficulty in adapting to other or related plant species.

Psyllid fossils have been found from the early Permian before the flowering plants evolved. The explosive diversification of the flowering plants in the Cretaceous was paralleled by a massive diversification of associated insects, and many of the morphological and metabolic characters that the flowering plants exhibit may have evolved as defenses against herbivorous insects.

Coevolution

Insect-plant interactions have been important in defining models of coevolution and cospeciation, referring to whether plant speciation drives insect speciation and vice versa, though most herbivorous insects probably evolved long after the plants they feed on.
