Carcina quercana
oak lantern, long-horned flat-body, oak-skeletonizer moth
Carcina quercana is a small moth in the family Peleopodidae (Depressariidae), native to Europe and recently introduced to western North America. It is distinguished by its pastel purple and yellow wing patterning and notably long antennae. The species is moderately polyphagous on deciduous trees, particularly favoring Fagaceae. Adults fly from May to October, with peak activity in July.
Cynipini
Oak Gall Wasps
Cynipini is the largest tribe of gall wasps in the family Cynipidae, comprising approximately 936 to 1,000 described species. Members are commonly known as oak gall wasps due to their specialized association with oaks (Quercus) and other Fagaceae. The tribe is primarily distributed in the Holarctic region, with significant diversity also in Mexico and Central America. Cynipini species induce structurally diverse galls on various oak tissues including leaves, buds, branches, petioles, catkins, acorns, and roots. Most species exhibit cyclical parthenogenesis, alternating between sexual and asexual generations that often produce different gall morphotypes on the same or different host tissues.
Ectoedemia
Ectoedemia is a genus of minute moths in the family Nepticulidae, established by August Busck in 1907. The genus comprises four subgenera: Ectoedemia, Etainia, Fomoria, and Zimmermannia. Species are distributed across multiple continents including Europe, Asia, Africa, Australia, and the Americas. The genus is notable for its leaf-mining larval ecology, with many species exhibiting narrow host plant specificity on trees and shrubs.

Greenideinae is a subfamily of aphids (Aphididae) comprising approximately 179 extant species across 18 genera in three tribes: Cervaphidini, Greenideini, and Schoutedeniini. Species are primarily distributed in eastern and southern Asia, with many exhibiting specialized associations with woody host plants, particularly in Fagaceae. The subfamily has been extensively studied for its complex symbiotic relationships with microbial associates, including the primary endosymbiont *Buchnera aphidicola* and diverse secondary symbionts.
New-genus-near-neurobathra
This genus represents a newly recognized lineage of leaf-mining moths within Gracillariidae, positioned phylogenetically near Neurobathra. It comprises species that construct serpentine or blotch mines in living leaf tissue. The genus was erected to accommodate taxa previously misassigned or undescribed, distinguished by unique genitalic and larval morphological features.
Synergini
inquiline gall wasps
Synergini is a tribe of inquiline gall wasps in the family Cynipidae. Members have lost the ability to induce their own galls and instead inhabit galls created by other cynipid wasps, primarily those in tribe Cynipini. The tribe includes genera such as Synergus, Saphonecrus, Lithosaphonecrus, and Ufo. Most species are associated with oaks (Quercus) and related Fagaceae. A 2015 taxonomic revision transferred three former Synergini genera to other tribes: Ceroptres to its own tribe Ceroptresini, and Periclistus and Synophromorpha to Diastrophini.
Tischeria quercitella
Oak Blotch Miner Moth
Tischeria quercitella is a leaf-mining moth in the family Tischeriidae. Its larvae create distinctive blotch mines on the leaves of oaks (Quercus) and chestnuts (Castanea). The species is documented across eastern North America, with records from Ontario south to Virginia and west to Missouri and Illinois.
Tuberculatus
Tuberculatus is a genus of aphids in the family Aphididae, established by Aleksandr Mordvilko in 1894. Species in this genus feed exclusively on trees in the family Fagaceae, including oaks, beeches, and chestnuts. The genus exhibits a cosmopolitan distribution and contains species with two contrasting ecological strategies: ant-attended and non-attended populations. Research on Tuberculatus has focused extensively on its symbiotic relationships with ants and bacteria.
