Species abortivaria (The Bad-Wing - Hodges#7648)
Hodges Number
7648
Other Common Names
The Bad Wing
Explanation of Names
Called "The Bad-Wing" because the small hindwings are difficult to pull into position for pinning. The name of the genus also means bad wing - from the Greek "dys" (bad, difficult) + "pteron" (wing). Even the specific epithet abortivaria doesn't sound good, perhaps suggesting that various attempts or methods of pinning the wings have been aborted.
Numbers
the only species in this genus in North America
Size
Wingspan 20-28 mm
Identification
Adult: completely green, including head, thorax, abdomen, legs, and wings
forewing bluish-green, grayish-green, or bright green; costa with inward curve near apex, giving round-tipped appearance; antemedial (AM) and postmedial (PM) lines faint white, fairly straight, fading just before reaching costa; small white discal spot near middle of wing; hindwing similar color to forewing but much smaller (less than half the size of forewing)
Range
eastern North America (Quebec to Florida, west to Texas, north to Manitoba)
Habitat
Near edges, woodlands, with hostplants.
Season
Adults fly from mid-April to August.
Food
Larvae feed on grape (Vitis spp.) and Virginia Creeper (Parthenocissus spp.)
Adults likely do not feed.
Life Cycle
two generations per year
See Also
other green geometrids (in the subfamily Geometrinae) do not have such a pronounced curve in the tip of the forewing, and they usually have some yellowish or brown color on the head and/or abdomen, rather than being completely green
