Agonopterix pteleae
A small moth in the family Depressariidae, described from North America in 1920. Adults have distinctive mottled brown forewings with prominent dark markings. Larvae are known to feed on Ptelea trifoliata (common hoptree). The species has a restricted distribution centered on the Great Lakes region.
Heraclides
New World Giant Swallowtails and Allies
Heraclides is a genus of swallowtail butterflies (family Papilionidae) native to the Americas, commonly referred to as the New World Giant Swallowtails and Allies. These are large, conspicuous butterflies often with bold black and yellow or black and green coloration. The genus includes species formerly classified under Papilio subgenus Heraclides, now generally treated as a distinct genus based on morphological and molecular evidence. Members are known for their strong flight and association with citrus and related host plants.
Leuronota fagarae
Wild Lime Psyllid
Leuronota fagarae (Wild Lime Psyllid) is a psyllid species in the family Triozidae, native to Paraguay and invasive in Florida, USA since 2001. It feeds on Zanthoxylum fagara (wild lime), a citrus relative in the Rutaceae family, causing characteristic rolled leaf edges that shelter developing nymphs. The species is taxonomically related to Diaphorina citri, the vector of Huanglongbing (citrus greening), and their ranges overlap in Florida's transition zones between wild and cultivated citrus habitats. A novel Wolbachia endosymbiont strain (wLfag-FL, supergroup B) has been characterized from this species, revealing potential nutritional provisioning roles and informing research on symbiont-based pest control strategies.
Thryallis
Thryallis is a genus of longhorn beetles (Cerambycidae: Lamiinae: Anisocerini) established by Thomson in 1858. The genus is known to include species that function as wood-boring agricultural pests. Thryallis undatus has been documented damaging Persian lime orchards in Veracruz, Mexico, where larvae tunnel into trunks and branches causing tree mortality. The genus name has been subject to nomenclatural confusion with a plant genus of the same name in Malpighiaceae.
Thryallis undatus
Thryallis undatus is a longhorn beetle (Cerambycidae: Lamiinae: Anisocerini) first described by Chevrolat in 1834. The species has been documented as a pest of Persian lime (Citrus latifolia) in commercial orchards in Veracruz, Mexico, where adults oviposit on trunks and branches and larvae create galleries 2–5 cm deep. This represents the first record of the species associated with the Rutaceae family. Native distribution includes Middle America and North America, with records from Guatemala and Honduras.
