Eriocampa juglandis
Butternut Woollyworm, Butternut Woollyworm Sawfly, Butternut Wooly Worm
Eriocampa juglandis, commonly known as the butternut woollyworm, is a sawfly in the family Tenthredinidae. The larvae feed on leaves of butternut, black walnut, and hickory trees, and are notable for their distinctive white, woolly wax coating. Unlike true caterpillars, sawfly larvae possess six or more pairs of prolegs on their abdominal segments. The species has one generation per year, with larvae active in mid-summer and pupation occurring in soil over winter.
Goes pulcher
Living-hickory Borer
Goes pulcher is a wood-boring beetle in the family Cerambycidae, commonly known as the Living-hickory Borer. First described by Haldeman in 1847, it develops in living hickory (Carya) and pecan (Carya illinoinensis) trees. Larvae tunnel beneath the bark, damaging cambium and sapwood. The species has a 2-3 year life cycle and is distributed across Canada and the United States.
Knulliana
banded hickory borer
Knulliana is a monotypic genus of longhorn beetles (family Cerambycidae) containing the single species Knulliana cincta, commonly known as the banded hickory borer. The genus was established by Linsley in 1962 and is classified within the tribe Bothriospilini. The sole species ranges across the eastern half of North America from Canada to the Bahamas and Mexico, with one subspecies extending into the Sonoran Desert. Adults are associated with hickory and oak trees, where larvae develop as wood-borers.
Longistigma caryae
Giant Bark Aphid
Longistigma caryae, commonly known as the giant bark aphid, is the largest aphid species native to the United States. First described in 1841 from pignut hickory in Massachusetts, this species was later placed in its own genus due to its distinctive extremely long, slender stigma that extends around the end of the wing. It feeds on the bark of hickory trees and has been documented across eastern and central North America.
Periclista
common sawflies
Periclista is a genus of sawflies in the family Tenthredinidae, subfamily Blennocampinae, comprising at least 20 described species. Larvae are external feeders on oak (Quercus) and hickory (Carya) foliage. The genus is distinguished by larval morphology, particularly the presence of branched dorsal spines. Adults are typical of the family, with a broad connection between thorax and abdomen lacking the constricted waist seen in other Hymenoptera.
Phylloxera symmetrica
Phylloxera symmetrica is a gall-forming insect in the family Phylloxeridae, closely related to aphids. Like other phylloxerans, this species induces abnormal plant growths (galls) on host plants through chemical secretions that manipulate plant development. The species was described by Pergande in 1904. Members of the genus Phylloxera are known for complex life cycles involving both sexual and asexual generations, with overwintering eggs and multiple gall-forming generations per year.
Prociphilus caryae
hickory woolly aphid
Prociphilus caryae, the hickory woolly aphid, is a species of woolly aphid in the family Aphididae. Like other members of the genus Prociphilus, this species is characterized by dense white waxy secretions that cover the body, giving it a distinctive woolly appearance. The species is associated with hickory trees (Carya spp.) as its primary host. Woolly aphids in this genus are known for complex life cycles that typically involve host alternation between a primary woody host and secondary herbaceous hosts, though specific details for P. caryae are not well documented in available sources.
Purpuricenus axillaris
White Oak Branch Girdler
Purpuricenus axillaris is a large, showy longhorned beetle in the family Cerambycidae, described by Haldeman in 1847. It is one of three eastern North American species in the genus Purpuricenus, distinguished by transverse basal elytral markings that cover the entire basal half of the elytra in yellow to orange coloration. The species is strongly attracted to fermenting bait traps and has been documented in association with hickory (Carya) as its larval host. It was historically confused with the similar but distinct P. paraxillaris, which was described as a new species in 2000.
Saperda discoidea
Hickory Saperda
Saperda discoidea is a longhorned beetle species in the family Cerambycidae, first described by Fabricius in 1798. It is commonly known as the Hickory Saperda. The species belongs to the genus Saperda, a group of wood-boring beetles whose larvae develop in living or stressed deciduous trees. Like other members of its genus, this species is associated with hardwood hosts, with hickory indicated by its common name. It occurs in North America with records from Canada (Ontario and Québec) and the United States.
Satyrium caryaevorus
Hickory Hairstreak
Satyrium caryaevorus, the hickory hairstreak, is a small butterfly in the family Lycaenidae. It is found in eastern North America, where adults are active during summer months. The species has one generation per year and overwinters as an egg. Larvae feed primarily on hickory and related tree species, while adults visit flowers for nectar.
Saucrobotys fumoferalis
dusky saucrobotys moth
Saucrobotys fumoferalis is a small crambid moth found across northern and western North America. Adults are active from spring through late summer, with a wingspan of approximately 30 mm. The species is notable for its larval association with hickory trees (Carya species), where caterpillars feed on leaves. It inhabits boreal forests, mixed forests, and woodlots across a broad geographic range from the Yukon to California and from Nova Scotia to British Columbia.
Scolytus quadrispinosus
Hickory Bark Beetle
Scolytus quadrispinosus, commonly known as the hickory bark beetle, is a bark beetle species in the family Curculionidae. It is native to North America and has been documented in Canada (Ontario, Québec) and the United States. The species is associated with hickory and related host trees. Its dispersal flight behavior has been studied in relation to host specificity, with individuals attracted to host material during flight.
Stigmella undescribed-species-on-carya
An undescribed species of pygmy moth in the family Nepticulidae, genus Stigmella, associated with Carya (hickory) as a host plant. The species has not yet received a formal scientific name but is recognized as distinct based on host association and presumably morphological or genetic differentiation from described congeners.
