Comment: This species resembles A. eburnea, but has narrower wings and is a little larger overall. Additionally, castaneae is found on Castanea sp., while eburnea is found on Quercus sp. Coloration wise, it is similar to A. aurea and A. eburnea.
NOTE: A. Hamilton noted here that due to the chestnut blight in North America and the subsequent loss of chestnut trees across the country, A. castaneae could be extinct. HOWEVER, A. castaneae feeds on Dwarf Chestnut, not American chestnut, which is still very widespread (but still affected by the chestnut blight). A. castaneae is likely very localized and a possible species of concern. |
