Psylla carpinicola
Psylla carpinicola is a plant-parasitic hemipteran in the family Psyllidae, first described by Crawford in 1914. The species is associated with hornbeam (Carpinus) host plants, as indicated by its specific epithet 'carpinicola' meaning 'dwelling on hornbeam'. It is one of numerous psyllid species that feed on phloem sap and may induce gall formation on host plants. Like other psyllids, it has piercing-sucking mouthparts and undergoes incomplete metamorphosis with distinct egg, nymph, and adult stages.
