Fulgoridae

Latreille, 1807

lanternflies, lanthorn flies

Tribe Guides

is a large of planthoppers within the order Hemiptera, containing over 125 worldwide with exceptional diversity in tropical regions. Members range from moderate to large size and often exhibit brilliant, varied coloration that superficially resembles Lepidoptera. The family is commonly known as "lanternflies," a name derived from the historical misconception that the elongated processes of some could produce light. These insects possess adapted for feeding on plant phloem sap.

Identification

Distinguished from other planthopper by larger body size and often elaborate ornamentation. Superficial resemblance to Lepidoptera due to coloration, but can be recognized as Hemiptera by the beak-like rostrum folded beneath the head and the structure of the wings. The family-level identification of nymphs is challenging and often requires rearing to adulthood for definitive determination.

Habitat

Primarily tropical and subtropical forests; some extend into temperate regions. Associated with diverse plants including trees and shrubs. In North America, limited species occur in prairie and glade on specific host plants such as Silphium terebinthinaceum.

Distribution

Worldwide distribution with exceptional abundance and diversity in tropical regions, especially Southeast Asia, the Americas, and Africa. In the United States, native diversity is limited with only a few reaching as far north as Missouri; the spotted lanternfly (Lycorma delicatula) has established expanding in the eastern United States from Pennsylvania to multiple surrounding states.

Seasonality

Activity patterns vary by and latitude. In temperate regions, are typically active from late summer through autumn. Tropical species may be active year-round. The Lycorma delicatula in North America shows adult activity from September through December with -laying during this period.

Diet

Phloem-feeding; and nymphs pierce plant vascular tissue with needle-like mouthparts to extract sap. Some are , feeding on multiple plant species, while others show more restricted host associations. Heavy feeding produces copious honeydew .

Host Associations

Ailanthus altissima (tree of heaven) - primary Preferred for Lycorma delicatula
Vitis spp. (grapes) - Significant crop damage reported from Lycorma delicatula feeding
Juglans spp. (walnuts) - Commonly used by aggregating
Acer spp. (maples) - Frequently utilized trees
Silphium terebinthinaceum (prairie dock) - Documented for Poblicia fuliginosa in Missouri glades
Brickellia eupatorioides (false boneset) - Observed for Poblicia fuliginosa

Life Cycle

Hemimetabolous development with , nymph, and stages. Eggs are laid in masses, sometimes covered with waxy secretions; in some , egg masses are deposited on non- objects including stones, vehicles, and furniture. Nymphs pass through multiple instars (typically 4-5) before maturing to adults. Nymphs often show progressive color changes through development, such as the transition from black-and-white to red-black-and-white patterning in Lycorma delicatula.

Behavior

are capable of but often prefer to hop when disturbed; some are described as "rocket propelled" and extremely difficult to capture by hand netting. Many species exhibit negative geotaxis, crawling upward when placed on substrates. Adults of some species aggregate on preferred trees. Flash coloration may be employed: bright abdominal colors visible in flight disappear when wings fold over the at rest, potentially confusing . Some species participate in , being attended by geckos and that collect honeydew .

Ecological Role

Primary consumers as phloem-feeders; significant honeydew producers that support growth and attract other insects including stinging , hornets, yellowjackets, paper wasps, and honeybees. Some serve as trophobionts in mutualistic associations with other arthropods. such as Lycorma delicatula can cause substantial economic damage to vineyards, orchards, and forest through direct feeding damage and secondary effects of sooty mold.

Human Relevance

Several are significant agricultural and forestry pests, particularly the spotted lanternfly (Lycorma delicatula) in North America, which threatens grape production, orchards, and timber. Historical misconception that processes produced light led to such as laternaria, phosphorea, and candelaria. Some species are used in traditional Chinese medicine. measures and efforts are ongoing for invasive . Natural enemies including (Anastatus orientalis), predatory insects, and fungi ( bassiana, Batkoa major) are being investigated and utilized for .

Misconceptions

The "lanternfly" originated from Maria Sibylla Merian's 18th-century claim that the process of living insects was luminous at night. Carl Linnaeus perpetuated this error by coining specific epithets (laternaria, phosphorea, candelaria) reflecting the supposed luminescence. No actually produce light; the head structures are hollow cuticular processes with no bioluminescent capability.

Taxonomic instability

Molecular analyses in the 21st century have questioned the monophyly of as traditionally constituted. The Zanninae may not belong within Fulgoridae, and broader relationships within Fulgoromorpha remain under investigation.

Defensive chemistry

Lycorma delicatula sequesters cytotoxic alkaloids from plants, rendering it toxic to ; this is advertised by aposematic coloration. Some birds have been observed vomiting after ingestion.

Dispersal ecology

While capable of only limited self-powered (3-4 miles by , hopping, and flying), some are extraordinarily effective hitchhikers. Human-assisted transport of masses on vehicles, goods, and materials has facilitated rapid range expansion of across hundreds of miles.
