Guides

  • Amblycerus vitis

    Arizona Grape Bruchid

    Amblycerus vitis is a seed beetle (subfamily Bruchinae) commonly known as the Arizona Grape Bruchid. The species is a specialist herbivore associated with wild grape species in the genus Vitis, particularly in arid regions of the southwestern United States. As a member of the tribe Amblycerini, it exhibits the typical bruchid life history of larval development within seeds.

  • Ampelomyia

    Ampelomyia is a genus of gall midges in the tribe Asphondyliini (Diptera: Cecidomyiidae), erected in 2019 to accommodate species that induce galls on grape plants (Vitis). The genus contains four species: A. conicocoricis from Japan, and three Nearctic species transferred from other genera (A. viticola, A. vitiscoryloides, and A. vitispomum). All species are specialized gall inducers on Vitis species.

  • Ampelomyia viticola

    grape tube gallmaker, grape-leaf trumpet-gall, conical grape gall

    Ampelomyia viticola is a gall midge that induces distinctive tubular galls on grape vine leaves in eastern North America. The galls are narrow, conical structures measuring 7–10 mm long, typically crimson in color though green when young or on leaf undersides. Each gall contains a single larval chamber housing one pale yellowish-green to orange larva. The species was transferred from Schizomyia to the new genus Ampelomyia in 2019.

  • Ampelomyia vitiscoryloides

    grape filbert gall midge, grape filbert gall

    A gall midge (Cecidomyiidae) that induces galls on grape plants (Vitis). Originally described as Schizomyia vitiscoryloides by Packard in 1869, it was transferred to the new genus Ampelomyia in 2018 based on morphological and molecular phylogenetic evidence. Widespread in eastern North America.

  • Ampelomyia vitispomum

    Ampelomyia vitispomum is a gall midge species in the family Cecidomyiidae that induces galls on grape plants (Vitis spp.). It was first described by Carl Robert Osten-Sacken in 1878 and transferred to the genus Ampelomyia in 2018 based on morphological and molecular phylogenetic evidence. It is one of three Vitis-associated species in this genus found in the Nearctic region.

  • Eudryas unio

    Pearly Wood-nymph

    Eudryas unio, the pearly wood-nymph, is a noctuid moth native to eastern North America. Adults are active from May through August and have a wingspan of 26–35 mm. The species was historically confused with Eudryas brevipennis, but genitalia differences in both sexes confirm their separation. Isolated populations occur in central Utah and California, with the California population potentially representing a distinct subspecies.

  • Lasioptera vitis

    Grapevine Tomato Gall Fly

    Lasioptera vitis is a species of gall midge in the family Cecidomyiidae, commonly known as the Grapevine Tomato Gall Fly. The species is associated with grapevines (Vitis spp.), as indicated by its specific epithet. Like other members of the genus Lasioptera, it likely induces gall formation on host plants, though specific details about the morphology of its galls remain poorly documented in accessible literature.

  • Phymatodes amoenus

    Grapevine Phymatodes

    Phymatodes amoenus is a small to medium-sized longhorn beetle (family Cerambycidae) found in North America. The species is commonly known as the grapevine phymatodes due to its exclusive association with grape vines (Vitis spp.). Adults are typically found on dead grape vines, where they may occur alongside predatory checkered beetles (Cleridae) that prey upon their larvae. The species was first described by Thomas Say in 1824.

  • Vitacea

    Grape Root Borer Moths

    Vitacea is a genus of clearwing moths in the family Sesiidae, commonly known as grape root borer moths. The genus contains four recognized species, including Vitacea polistiformis, a significant agricultural pest of grape vineyards in the eastern United States. Adults are wasp mimics with reduced wing scaling that gives them a distinctive transparent appearance. Larvae are subterranean root borers that feed on grapevine roots, causing economically important damage to cultivated grapes.

  • Vitacea scepsiformis

    Lesser Grape Root Borer Moth

    Vitacea scepsiformis, the lesser grape root borer moth, is a clearwing moth in the family Sesiidae. It occurs across eastern and central North America, where its larvae develop as root borers in grapevines (Vitis species). Adults are active from mid-summer through early autumn and are wasp mimics in appearance. The species is smaller than the related grape root borer (Vitacea polistiformis) and generally considered less economically damaging.

  • Vitisiella brevicauda

    Grape Tumid Gallmaker Midge

    Vitisiella brevicauda, the Grape Tumid Gallmaker Midge, is a gall midge in the family Cecidomyiidae that induces characteristic tumor-like galls on grape (Vitis) leaves and stems. The species was described by Felt in 1908 and is primarily known from eastern North America. It is a minor pest in vineyards, where gall formation can reduce photosynthetic capacity and aesthetic value of grape foliage.
