Caloptilia sassafrasella
Sassafras Caloptilia Moth
Caloptilia sassafrasella is a small moth in the family Gracillariidae. The species is a specialist herbivore whose larvae mine leaves of sassafras trees (Sassafras spp.). Native to eastern North America, it has been documented from Canada south to Florida and west to Texas. Adults are nocturnal and attracted to light. The species was first described by Chambers in 1876.
Heilipus
pine weevils
Heilipus is a genus of New World weevils in the family Curculionidae, containing over 280 described species distributed from the southern United States to northern Argentina. The genus is characterized by two primary feeding guilds: seed borers that develop within fruits of Lauraceae, and trunk borers that tunnel into stems of host trees. Several species are significant agricultural pests, particularly of avocado (Persea americana) and other commercial crops. The Brazilian Atlantic Forest has been proposed as a possible center of origin for the genus based on high diversity of both weevils and host plants.
Heilipus squamosus
Avocado Weevil, Avocado Tree Girdler
Heilipus squamosus is a large weevil native to the southeastern United States and the sole species of its genus occurring in North America. It gained notoriety as the "avocado tree girdler," causing significant economic damage to Florida avocado groves from the late 1930s through the 1950s, with larval feeding resulting in 8-10% tree mortality. The species was historically considered rare outside avocado-producing regions, but 21st-century citizen science observations have expanded its known range from eight to fifteen states. Long confused with the French Guiana species H. apiatus due to an erroneous distribution in the original 1807 description, this nomenclatural issue was clarified in 2022.
Hylobiini
Hylobiini is a tribe of weevils within the subfamily Molytinae (Curculionidae). The tribe includes approximately 89 species in the genus Heilipus, which are distributed across the Americas. Members of this tribe are primarily associated with the plant family Lauraceae, with some species functioning as seed predators in fruits and others as bark-boring pests. The tribe contains three subtribes: Epistrophina, Hylobiina, and Incertae sedis.
Lauritrioza
bay sucker
Lauritrioza is a monotypic genus of psyllids (Hemiptera: Triozidae) containing the single species L. alacris. The genus is defined by its obligate association with Laurus species, on which it induces distinctive leaf-edge galls. Adults and nymphs inhabit these galls, with nymphs producing white waxy secretions. The genus has expanded from its native European range through human-mediated introduction to western North America, Brazil, and Jordan.
Lindera
spicebush, spicewood, Benjamin bush
Lindera is a genus of 80–100 species of flowering shrubs and small trees in the laurel family (Lauraceae). Most species occur in eastern Asia, with three species native to eastern North America. The genus is characterized by strongly aromatic leaves and dioecious flowers—male and female flowers occur on separate plants. Many species produce small red, purple, or black drupes dispersed by birds.
Papilio troilus
Spicebush Swallowtail, Green-clouded Butterfly
Papilio troilus, the spicebush swallowtail, is a black swallowtail butterfly native to eastern North America. Adults are primarily black with distinctive green-blue (male) or bright blue (female) half-moon markings on the hindwings, along with cream-yellow spots and orange basal patches. The species exhibits two subspecies: the widespread P. t. troilus and the Florida-endemic P. t. ilioneus. Larvae are notable for their dramatic ontogenetic color change, shifting from bird-dropping mimicry in early instars to snake-mimicry with large eyespots in later stages.
Phyllocnistis hyperpersea
Phyllocnistis hyperpersea is a microlepidopteran moth in the family Gracillariidae, described by Davis & Wagner in 2011. The species is notable for its distinctive leafmining behavior on Persea species, creating serpentine galleries on the upper leaf surface with an unusually broad median frass trail. Its specific name references this habit of mining on the upperside (hyper) of Persea leaves.
Phyllocnistis subpersea
Phyllocnistis subpersea is a microlepidopteran moth in the family Gracillariidae, described in 2011. Adults are tiny, with forewings measuring 2–2.7 mm. The species is a specialist leafminer on Persea borbonia, creating distinctive serpentine mines on the undersides of leaves. Its specific name references this sub-leaf mining habit. The species has a restricted known distribution in southeastern United States coastal regions.
Preponini
Preponini is a tribe of butterflies within the subfamily Charaxinae (Nymphalidae), comprising approximately 22 recognized species. Molecular systematics studies have significantly revised the group's classification: Anaeomorpha splendida was excluded to maintain tribal monophyly (reinstated as tribe Anaeomorphini), Noreppa was synonymized with Archaeoprepona, and Agrias was synonymized with Prepona. The tribe is distributed in the Neotropical region and includes some of the region's most visually striking butterflies.
Xyleborus glabratus
Redbay Ambrosia Beetle
Xyleborus glabratus is a small ambrosia beetle native to Asia that has become a destructive invasive pest in the southeastern United States since its detection in 2002. The species is the primary vector of Raffaelea lauricola, the fungal pathogen that causes laurel wilt disease, which has killed millions of native Lauraceae trees including redbay, sassafras, and avocado. Females are the dispersing sex and initiate galleries in host wood, where they cultivate fungal gardens as food for their offspring. The beetle's rapid spread threatens both forest ecosystems and commercial avocado production.
