''Catocala amica'', the girlfriend underwing, is an Erebidae species. It is found from southern Canada (Ontario and Quebec) through the United States east of the Rocky Mountains, ranging westward to Oklahoma and Arizona, northward to Minnesota and southwestward to Texas. ==Description and ecology== The wingspan of adults is 35–40 mm. They are generally easy to recognize by the cryptically patterned forewings, the yellow background color of their hindwings, and the black pattern on the latter. This consists of a black band along the outer edge, save for the hindmost part where a separate black dot is found. Forewing hue varies a lot, but similar sympatric species usually have an additional black band running across the central hindwings. Unlike in many (but not all) other underwing moths, their tibiae are all spineless.〔Nelson & Loy (1983)〕 Adults are on the wing from June to September depending on the location; they are often attracted to UV light at night. The caterpillars feed on oak (''Quercus'') species, including.〔 Of section ''Quercus'' * Bur oak (''Q. macrocarpa'') * Chestnut oak (''Q. prinus'') * Dwarf chinkapin oak (''Q. prinoides'') * Post oak (''Q. stellata'') * Swamp white oak (''Q. bicolor'') * White oak (''Q. alba'') Of section ''Lobatae'' * Bear oak (''Q. ilicifolia'') * Eastern black oak (''Q. velutina'') * Northern red oak (''Q. rubra'') * Scarlet oak (''Q. coccinea'') 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Catocala amica」の詳細全文を読む スポンサード リンク
