Arge
Arge is a genus of sawflies in the family Argidae, subfamily Arginae. Members of this genus are distributed across the Northern Hemisphere, with records from Europe and North America. As with other argid sawflies, species in this genus are herbivorous and typically associated with various woody plants as larvae. The genus was established by Schrank in 1802 and remains taxonomically valid.
Caliroa quercuscoccinae
Oak-skeletonizing sawfly
Caliroa quercuscoccinae is a sawfly species in the family Tenthredinidae. The larvae are known for skeletonizing oak leaves, feeding on the tissue between the leaf veins while leaving the veins intact. This feeding pattern creates a distinctive lace-like appearance on damaged foliage. The species is part of a genus whose larvae are commonly referred to as slug sawflies due to their slimy, slug-like appearance and locomotion.
Dietzella zimmermanni
minute seed weevil
Dietzella zimmermanni is a small weevil species in the family Curculionidae. Larvae are known to feed on leaves of specific host plants in the evening primrose family, including Oenothera pilosella, with this association representing the first documented larval host record for the species. The species occurs across North America with records from Canada and the United States.
Eucirroedia pampina
Scalloped Sallow
Eucirroedia pampina, commonly known as the scalloped sallow, is a moth in the family Noctuidae. It is widely distributed across eastern and central North America, with adults active from late summer through early winter. The species is recognized by its distinctive scalloped wing margins and moderate size. Larvae are known to feed on the leaves of several hardwood tree species.
Friseria cockerelli
mesquite webworm moth, mesquite webworm
Friseria cockerelli is a small moth in the family Gelechiidae, commonly known as the mesquite webworm moth. Its larvae are web-forming caterpillars that feed on mesquite (Prosopis spp.) and construct silk webs on host plants. The species occurs in Mexico and the southern United States, with adults active primarily from April to September.
Leptostales
Leptostales is a genus of geometrid moths in the subfamily Sterrhinae, established by Möschler in 1890. The genus contains multiple species, with Leptostales ignifera being the most studied due to its potential as a biocontrol agent for the invasive weed Lantana camara. Members are leaf-feeding moths found in subtropical regions of the Americas.
Rusicada privata
Hibiscus Leaf Caterpillar Moth
Rusicada privata is a moth in the family Erebidae, commonly known as the hibiscus-leaf caterpillar moth. The species was first described by Francis Walker in 1865. It occurs in East Asia (China, Taiwan, Japan) and has been recorded in North America, particularly the northeastern United States. The specific epithet and common name suggest an association with hibiscus plants.
Scelolyperus smaragdinus
Emerald Skeletonizing Leaf Beetle
Scelolyperus smaragdinus is a skeletonizing leaf beetle in the family Chrysomelidae. The species is found in North America and belongs to a genus of leaf-feeding beetles that characteristically skeletonize plant foliage by feeding on the tissue between leaf veins. The specific epithet "smaragdinus" refers to its emerald green coloration.
Schizocerella lineata
Outer Purslane Sawfly
Schizocerella lineata is a sawfly species in the family Argidae, historically confused with S. pilicornis until mitochondrial DNA analysis confirmed their separation in 2007. Unlike its congener, whose larvae are internal leaf miners, S. lineata larvae feed externally on purslane leaves. The species occurs widely across the New World from southern Canada to at least Central America, with multiple generations annually in warmer regions.
