Bt-corn-induced area-wide suppression of European corn borer is one of the most-cited examples of GMO BENEFITS BEYOND DIRECT YIELD PROTECTION in modern agricultural biotechnology curricula.

Native to the Americas — INVADED AFRICA in 2016 (Nigeria), Asia in 2018-19 (India, China), Australia in 2020. One of the most rapid documented insect range expansions in modern history.

African crop losses estimated at $2-6 BILLION ANNUALLY in maize alone — devastating impact on a continent where maize is the staple food crop for hundreds of millions of people.

Attacks OVER 350 PLANT SPECIES — major impact on maize, rice, sorghum, cotton, soybean, sugarcane, alfalfa, and many other crops.

Diagnostic field-ID feature is a distinctive INVERTED 'Y'-SHAPED MARKING on the head capsule — distinguishes fall armyworm from other Spodoptera and similar caterpillars.

Bt CORN provides good control of fall armyworm — a major contrast between protected US/Argentina maize sectors (with Bt corn) and vulnerable African and Asian sectors (often lacking widespread Bt corn adoption).

One of the most economically destructive STORED-GRAIN PESTS in the world — attacks stored rice, wheat, corn, sorghum, barley, oats. Causes 10-25% loss of stored cereal grains in tropical and subtropical regions.

Larvae develop INSIDE INDIVIDUAL GRAIN KERNELS — one larva per kernel. Eats the kernel hollow over 3-4 weeks before pupating inside the now-hollowed kernel.

Essentially COSMOPOLITAN — present in every major grain-producing and grain-storing region worldwide. Spread globally with cereal grain commerce since prehistoric times.

Combined annual GLOBAL LOSSES total TENS OF BILLIONS OF DOLLARS — major food security issue in tropical and subtropical regions where storage conditions are poor and pest pressure is high.

Phosphine fumigation is the most-used commercial control approach — but RAPID RESISTANCE EVOLUTION is a major problem, requiring development of alternatives like hermetic storage and modified-atmosphere storage.

Attacks an even BROADER RANGE of host trees than its Asian longhorned beetle cousin — OVER 100 DOCUMENTED HOST SPECIES including citrus, maple, oak, willow, ash, plane tree, sycamore.

Invaded Italy in 2000 — established population in Lombardy region. Also invaded Switzerland, Netherlands, France, and the US (eradicated detections in Washington 2001 and Georgia 2008-2010).

Distinguished from Asian longhorned beetle by BLUISH-WHITE BAND OF HAIRS at the base of the abdomen (visible from below — citrus longhorned has the band, Asian longhorned does not).

Multiple intercepted shipments of Anoplophora chinensis (often inside IMPORTED BONSAI PLANTS from Asia) have been documented at US, Canadian, and European ports of entry — flagship case in plant trade quarantine.

One of the most-quarantined insects in INTERNATIONAL PLANT TRADE — extensive regulatory restrictions on movement of bonsai, ornamental plants, and solid wood material from regions where the species occurs.

Primary VECTOR of DUTCH ELM DISEASE in North America — adults emerge from infected dead elm trees carrying Ophiostoma novo-ulmi fungal spores and transmit the disease to healthy elms during feeding.

Dutch elm disease has killed TENS OF MILLIONS OF AMERICAN ELM TREES across NA since the disease arrived in the 1930s — one of the most catastrophic tree-disease epidemics in NA history.

Transformed NA cities — American elm was historically the most-planted street tree in NA, with elm-lined streets defining urban landscapes. Mature American elms essentially eliminated from most NA cities by the 1980s.

Native to Europe — accidentally introduced to NA in the 1930s via imported elm logs. Spread aggressively across NA over the past 90 years, spreading Dutch elm disease as it expanded.

Modern DUTCH-ELM-DISEASE-RESISTANT CULTIVARS — 'Princeton', 'Valley Forge', and 'Liberty' elms — have been developed and are increasingly planted to restore American elms to NA urban landscapes.

Locust borers are striking BATESIAN MIMICS of wasps — bright yellow-and-black banded body with zigzag black markings on yellow elytra. Bird and small-mammal predators avoid attacking the harmless beetle.

Single most economically important PEST OF BLACK LOCUST (Robinia pseudoacacia) in NA — larvae tunnel into the inner bark and sapwood of host trees, weakening trunk structure.

Adult activity coincides with PEAK GOLDENROD FLOWERING in late September-October across eastern US — adults gather in dense aggregations on goldenrod flower clusters in autumn.

Historically a major problem for BLACK LOCUST utility wood — substantially reduced the value of black locust used in fence posts, mine timbers, and other applications. Modern impact reduced as black locust is less commonly cultivated.

Larvae feed EXCLUSIVELY on black locust (Robinia pseudoacacia) — narrow host plant restriction defines the species' geographic range and tightly couples species' fortunes to those of black locust.

The ONLY SKIPPER BUTTERFLY IN NORTH AMERICA with prominent hindwing tails — two long ribbon-like tails extending from each hindwing make the species exceptionally distinctive.

BRILLIANT METALLIC GREEN COLORATION on the body and inner halves of the wings — the iridescent green is one of the most striking colorations among NA skippers.

Major MIGRATORY SKIPPER — adults migrate north from year-round populations in southern FL, TX, and Mexico each summer. Rare migrants reach as far north as southern New England.

Larvae are known as 'BEAN LEAFROLLERS' — green caterpillars that ROLL leaf edges of legume host plants together with silk to construct shelters where the larva rests during the day.
