Acrobasis ostryella
Acrobasis ostryella is a snout moth (family Pyralidae) described by Charles Russell Ely in 1913. The species has one generation per year and occurs in eastern North America. Larvae are specialized feeders on Ostrya virginiana (American hophornbeam), constructing silk tubes at the base of leaves where they overwinter. The species is one of approximately 60 Acrobasis species in North America, many of which are associated with woody host plants.
Agrilus corylicola
Agrilus corylicola is a jewel beetle (family Buprestidae) described by Fisher in 1928. The species is associated with Corylus (hazelnut) host plants, as indicated by its specific epithet. It belongs to the large genus Agrilus, which contains numerous host-specific woodboring beetles. The species has been documented in the eastern United States, with potential occurrence in Missouri suggested by host plant presence, though confirmed records from the state appear limited.
Argyresthia goedartella
bronze alder moth
Argyresthia goedartella, commonly known as the bronze alder moth, is a small moth species in the family Argyresthiidae. It is widely distributed across Europe and North America. The species is recognized by its distinctive coppery-golden Y-shaped wing marking and its association with birch and alder host plants. Adults are active from spring through autumn and have been observed feeding on nectar.
Calaphidini
Calaphidini is a tribe of aphids in the subfamily Calaphidinae, family Aphididae. The tribe comprises approximately 18 genera divided into two subtribes: Calaphidina and Monaphidina. Members are phloem-feeding insects associated primarily with woody host plants, particularly in the families Betulaceae and Salicaceae. The tribe was established by Oestlund in 1919 and is widely distributed across temperate regions of the Northern Hemisphere.
Caloptilia ostryaeella
Ironwood Leafcone Moth
Caloptilia ostryaeella is a small moth in the family Gracillariidae, commonly known as the Ironwood Leafcone Moth. The species is known from eastern North America, with records from Québec, Canada, and several states in the northeastern and midwestern United States. Its larvae are specialized leaf miners that feed on species of hophornbeam (Ostrya) and hornbeam (Carpinus).
Corythucha coryli
hazelnut lace bug
Corythucha coryli, the hazelnut lace bug, is a species of lace bug in the family Tingidae. It is found in North America. The species is associated with hazelnut (Corylus) and other plants in the birch family (Betulaceae). Like other lace bugs, it feeds on plant sap and produces characteristic white stippling damage on leaves.
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.

Heterarthrus is a genus of sawflies in the family Tenthredinidae. Species occur in Eurasia and North America. The genus includes leafmining species that feed on trees in the family Betulaceae. Heterarthrus vagans, a Palaearctic species, has been introduced to southwestern British Columbia, Canada, where it mines leaves of native red alder.
Macrosiphum coryli
American Hazelnut Aphid
Macrosiphum coryli is an aphid species in the family Aphididae, commonly known as the American Hazelnut Aphid. It is a specialist feeder associated with plants in the genus Corylus (hazelnuts). The species was described by Davis in 1914 and is currently accepted as valid, though it has been placed in the subgenus Neocorylobium within Macrosiphum by some treatments. It belongs to a genus of aphids that includes several economically significant species affecting agricultural crops.
Oncopsis
Oncopsis is a genus of leafhoppers in the family Cicadellidae, subfamily Macropsinae. The genus is characterized by pronotal striations that run parallel to the hind margin. Species occur across the Holarctic region, with documented diversity in Europe, Asia, and North America. Many species exhibit strong host plant specificity, particularly for trees in the families Betulaceae and Corylaceae.
Purshivora coryli
Hazelnut psyllid
Purshivora coryli is a psyllid species in the family Psyllidae that feeds on hazelnut (Corylus species). Psyllids, also known as jumping plant lice, are small sap-feeding insects with host-specific relationships to their plant hosts. This species is associated with the genus Corylus in the birch family Betulaceae. The genus Purshivora comprises species specialized on hosts within Betulaceae.
Saperda obliqua
Alder Borer
Saperda obliqua is a longhorn beetle in the family Cerambycidae, described by Thomas Say in 1826. It is commonly known as the Alder Borer due to its association with alder trees (Alnus spp.). The species occurs in Canada and the United States, with its southwestern distributional limit in Missouri.
