Aceria negundi
box elder pouch gall mite
Aceria negundi, commonly known as the box elder pouch gall mite, is an eriophyid mite that specializes on box elder (Acer negundo). This microscopic arachnid induces characteristic pouch galls on its host plant. Like other members of the Eriophyidae, it has a worm-like body with four legs and is among the smallest plant-parasitic mites, measuring less than 0.2 mm in length. The species has been observed across a broad geographic range with over 4,700 documented observations.
Archips negundana
Larger Boxelder Leafroller Moth
Archips negundana, the larger boxelder leafroller moth, is a small tortricid moth native to North America. Adults are active in July and have a wingspan of 18–21 mm. The species was first described by Harrison Gray Dyar Jr. in 1902. Larvae are known to feed on boxelder (Acer negundo), nettle (Urtica), and honeysuckle (Lonicera), rolling leaves for shelter.
Boisea rubrolineata
Western Boxelder Bug
Boisea rubrolineata, the western boxelder bug, is a scentless plant bug native to western North America, ranging west of the Continental Divide. This species is a specialist herbivore primarily associated with boxelder maple (Acer negundo), feeding on both pollen from staminate trees and seeds from pistillate trees. Distinguished from its eastern counterpart B. trivittata by prominent red veins on the corium, it exhibits complex semiochemical-mediated behaviors including aggregation and host foraging. The species undergoes incomplete metamorphosis and seeks sheltered overwintering sites in autumn, often becoming a nuisance pest when entering human structures.
Caloptilia negundella
Boxelder Leafroller Moth, boxelder leafroller
Caloptilia negundella is a small moth in the family Gracillariidae, commonly known as the boxelder leafroller moth. The species was first described by V.T. Chambers in 1876. It is attracted to ultraviolet light sources and has been documented at moth lighting events in Colorado.
Contarinia negundinis
boxelder gall midge, boxelder bud gall midge, boxelder leaf gall midge
Contarinia negundinis, commonly known as the boxelder gall midge, is a species of gall midge in the family Cecidomyiidae. It induces galls on boxelder (Acer negundo) and is the only North American species in its genus known to enter diapause during the pupal stage. The species is distributed in parts of the United States including Vermont.
Contarinia undescribed-species-on-boxelder
An undescribed species of gall midge in the genus Contarinia associated with boxelder (Acer negundo). As a member of the family Cecidomyiidae, this species likely forms galls or induces other plant growth abnormalities during larval development, though formal taxonomic description remains pending. The specific epithet reflects its documented association with this host plant rather than a formally published species name.
Elaphria festivoides
festive midget
A small noctuid moth of eastern North America, distinguished from close relatives by genitalia and subtle wing pattern differences. Adults are active from spring through mid-summer with multiple generations. Larval host records exist for boxelder maple. The species was taxonomically revised in 2003, with Canadian populations reassigned to the newly described E. alapallida.
Periphyllus negundinis
Box Elder Aphid
A North American aphid species specialized on box elder trees. Forms dense colonies on leaves and stems, often becoming conspicuous due to honeydew production and associated sooty mold. The species was first described in 1878 and remains a common, well-documented member of the aphid genus Periphyllus.
