Euzophera magnolialis
magnolia root borer
Euzophera magnolialis is a snout moth described by Capps in 1964, restricted to the southern United States. Its common name, magnolia root borer, reflects its specialized larval habit of boring into the roots of Magnolia grandiflora. The species has a wingspan of 34–41 mm. It is one of approximately 50 species in the genus Euzophera, a group of small moths whose larvae typically feed internally in plant tissues.

Exapion ulicis
Gorse Seed Weevil
Exapion ulicis is a small seed-feeding weevil specialized on gorse (Ulex europaeus). Adults are light gray with a prominent snout roughly half the body length. The species is native to western Europe and has been introduced to New Zealand, California, Hawaii, and other regions as a biological control agent targeting invasive gorse populations. Larval feeding destroys seeds within pods, reducing plant spread, while adult feeding on stems and spines causes minor damage.

Hylurgopinus rufipes
Native Elm Bark Beetle
The native elm bark beetle is a small scolytine weevil and principal vector of Dutch elm disease in the northern Great Plains and prairie provinces of Canada. Adults are brownish-red, measuring 2.3–2.9 mm, and complete one generation annually. Overwintered adults emerge in spring to colonize weakened or dying American elm, constructing egg galleries in the inner bark where larvae feed on cambium tissue. The species exhibits distinctive acoustic communication: males produce simple multipulse calls, stress/rivalry chirps, and bimodal premating stridulation at gallery sites, while females do not stridulate. Males become strongly arrested at attractive female galleries and engage in brief contests with rival males shortly after a resident male establishes presence.

Lipara lucens
Cigar Gall
Lipara lucens is a gall-forming frit fly (Diptera: Chloropidae) that induces characteristic cigar-shaped galls on common reed (Phragmites australis). The species is monophagous, completing its entire larval development within reed stems. Males produce species-specific acoustic signals through wing vibration and abdominal movement to locate females, who respond with answering vibrations. This substrate-borne communication reduces mate-searching time by allowing males to rapidly assess reed stems for receptive females.

Macrosiphum tuberculaceps
sweet-after-death aphid
Macrosiphum tuberculaceps is an aphid species endemic to the Pacific Northwest region of North America. It is commonly known as the sweet-after-death aphid due to its exclusive association with its host plant, sweet-after-death (Achlys triphylla). The species exhibits distinctive morphological features including antennae longer than its teardrop-shaped body, short siphunculi inflated at the base with blackish tips, and legs longer than the body length. Its highly specialized host relationship makes it a notable example of monophagy among aphids.

Myzus lythri
loosestrife aphid
Myzus lythri is a specialized aphid species that feeds exclusively on purple loosestrife (Lythrum salicaria). It has been used as an indicator species to track the distribution and spread of this invasive weed in North America. Suction trap surveys in Idaho demonstrated that aphid collection patterns successfully predicted undocumented purple loosestrife populations, representing a novel application of insect survey data for weed documentation.

Neodiprion pinetum
White Pine Sawfly
Neodiprion pinetum is a conifer-feeding sawfly native to eastern North America. Adults are broad-bodied, stingless wasps with females bearing a saw-like ovipositor used to insert eggs into pine needles. Larvae are creamy-yellow with black heads and four longitudinal rows of black spots, resembling caterpillars but possessing more prolegs. The species is frequently monophagous on eastern white pine (Pinus strobus), though larvae have been documented on several other pine species. Localized outbreaks occur regularly and can kill small stands of host trees, though natural enemies including egg and larval parasitoids typically provide substantial biological control.

Obolodiplosis robiniae
locust gall midge, black locust gall midge
Obolodiplosis robiniae is a small gall midge (Diptera: Cecidomyiidae) native to eastern North America that has become a significant invasive pest in Eurasia. The species is monophagous on Robinia species, particularly black locust (Robinia pseudoacacia), forming distinctive leaf margin roll galls through gregarious larval feeding. First described from Pennsylvania in 1847, it was detected in Asia in 2002-2003 (Japan, Korea) and Europe in 2003 (Italy), subsequently spreading explosively to 26 European countries and much of China. Climate modeling predicts substantial northward range expansion under warming scenarios, with suitable habitat potentially increasing by 35% by 2070. The midge reduces host tree growth and productivity, causes early leaf abscission, and facilitates secondary pest attacks by wood-boring beetles.
