Diaethria
eighty-eight butterflies
Diaethria is a genus of brush-footed butterflies in the subfamily Biblidinae, distributed across the Neotropics from Mexico to Paraguay. The genus is renowned for distinctive ventral hindwing patterns that resemble the numerals "88" or "89," formed by black dots surrounded by concentric white and black lines. Adults are vividly colored with aposematic black, white, and red wing patterns. The genus comprises approximately twelve described species, including well-known taxa such as D. clymena and D. anna.
Hydririni
Hydririni is a tribe of moths in the subfamily Spilomelinae (family Crambidae) comprising approximately 104 species across eight genera. The tribe is primarily Neotropical in distribution, with most species described from tropical Central and South America. Adults range from narrow- to broad-winged, with wing patterns varying from inconspicuous brown and ochre to more colorful displays. Hydririni is characterized by distinctive genitalic synapomorphies: females possess an appendix bursae on the corpus bursae, and males typically exhibit hair scale patches on the anterior edge of abdominal sternite 8. The tribe forms part of the paraphyletic 'non-euspilomeline' group within Spilomelinae.
Jadera
soapberry bugs, red-shouldered bugs, golden rain tree bugs
Jadera is a genus of scentless plant bugs in the family Rhopalidae, commonly known as soapberry bugs or red-shouldered bugs. The genus comprises 19 species restricted to the Americas, ranging from southern Canada through Argentina. Members are specialized seed-feeders on plants in the family Sapindaceae, particularly balloon vines (Cardiospermum) and golden rain trees (Koelreuteria). Jadera haematoloma is the most extensively studied species, serving as a classic model for rapid evolutionary adaptation to invasive host plants.
Jadera haematoloma
red-shouldered bug, goldenrain-tree bug, soapberry bug
Jadera haematoloma is a true bug in the family Rhopalidae, commonly known as the red-shouldered bug, goldenrain-tree bug, or soapberry bug. It feeds on seeds of plants in the soapberry family (Sapindaceae) and has become a classic model organism for studying rapid evolutionary adaptation to novel hosts. The species is notable for documented cases of contemporary evolution, including changes in beak length and life history traits following host shifts to introduced plants. It is frequently mistaken for boxelder bugs (Boisea spp.) due to similar coloration and habits.
Jadera hinnulea
Jadera hinnulea is a species of soapberry bug in the family Rhopalidae, described by Göllner-Scheiding in 1979. It belongs to a genus of true bugs that feed on seeds of plants in the family Sapindaceae. The species occurs in Central America and North America, though detailed ecological studies specific to this species appear limited in the available literature. Most research on Jadera ecology has focused on the more widespread Jadera haematoloma.
Lignyodes arizonensis
Lignyodes arizonensis is a species of weevil in the family Curculionidae, tribe Lignyodini. The genus Lignyodes comprises seed weevils associated with soapberry (Sapindus spp.) and related plants. The specific epithet "arizonensis" indicates a geographic connection to Arizona, though detailed published records for this particular species are limited. Members of this genus are characterized by their association with Sapindaceae host plants.
Melacoryphus admirabilis
Admirable Seed Bug
Melacoryphus admirabilis is a seed bug in the family Lygaeidae, native to the Nearctic region of North America. The species is closely related to other soapberry bugs and shares ecological associations with plants in the family Sapindaceae. It occurs in the southwestern United States and Mexico, typically in warm, arid habitats. Like other members of its genus, it feeds on seeds and plant fluids. The species is occasionally encountered in large aggregations.
