Chrysobothris purpureovittata purpureovittata
Chrysobothris purpureovittata purpureovittata is a subspecies of jewel beetle in the family Buprestidae, distributed primarily in the central and south-central United States. This taxon is notable for its exceptional polyphagy, having been reared from more than two dozen species of deciduous trees across eleven plant families. Adults are typically encountered by beating foliage, particularly of hackberry (Celtis spp.) and other members of Ulmaceae, though larval hosts span multiple families including Rosaceae, Fagaceae, and Rhamnaceae.
Eriosomatini
Eriosomatini is a tribe of gall-forming aphids in the subfamily Eriosomatinae, comprising approximately 140 species across 16 genera. All members induce galls on host plants in the family Ulmaceae, primarily on Ulmus (elms) and Zelkova species. The tribe exhibits complex life cycles with alternation between primary and secondary hosts, though some species have reduced or lost host alternation. Molecular studies have demonstrated that DNA sequencing can reliably associate morphologically distinct life stages to species, addressing a major identification challenge in the group.
Tautoneura
Tautoneura is a genus of leafhoppers in the family Cicadellidae, subfamily Typhlocybinae, tribe Erythroneurini, established by Anufriev in 1969. The genus is native to the eastern Palearctic and Indo-Malay region, with T. polymitusa being the first species recorded in Europe, where it has established adventive populations. Species in this genus are small, slender insects associated with trees in the family Ulmaceae.
Tautoneura polymitusa
Tautoneura polymitusa is a small leafhopper (2.4–2.7 mm) in the family Cicadellidae, first described from South Korea in 2016. It represents the first European record of both the species and the genus Tautoneura, having been detected in Hungary in 2012 and subsequently found in Italy, Spain, Slovenia, Ukraine, Russia, and Moldova. The species is associated with Ulmaceae (elm family) and has established stable, locally abundant populations in parts of Europe. It hibernates as adults and is attracted to light traps.
Tinocallis
elm aphids, crapemyrtle aphids
Tinocallis is a small genus of aphids in the subfamily Calaphidinae, comprising eight described species. Most species are associated with Ulmaceae (elm family), though one notable exception, T. kahawaluokalani (the crapemyrtle aphid), is a specialist pest of Lagerstroemia indica. Species exhibit holocyclic life cycles with both parthenogenetic summer generations and sexual autumn generations producing overwintering eggs. Several species are economically significant as pests of ornamental trees in urban landscapes.
Tinocallis ulmiparvifoliae
elm aphid
Tinocallis ulmiparvifoliae is a small aphid species in the family Aphididae, originally described by Matsumura in 1919. It belongs to the genus Tinocallis, a group of eight species primarily associated with Ulmaceae (elm family). The species is a specialist herbivore feeding on elm foliage. It has been recorded from Europe (Spain, Italy, Great Britain) and the United States.
