They report that late-instar larvae have been found on almost any type of foliage but it was unknown whether they can complete development on non- <i>Quercus</i> species. In their study, 1 st through 4 th instar larvae were raised on <i>Quercus nigra</i> (Water Oak), then switched to various alternate hosts in the 5 th instar, while others were successfully reared to pupation on <i>Q. nigra</i>. Suitable alternate hosts included: <i>Q. velutina</i> (Black Oak), and <i>Prunus serotina</i> (Black Cherry).

The largest of all <i>maia</i> populations. Wings decidedly brownish-black, solid opaque. The brownish tint is variable. While some individuals are black, a small percentage are clearly brown. Median bands are cream-colored. The forewing median band is located exterior to the discal streak in most specimens, thus maintaining a continuous band (inner edge of the median band intersects the discal streak). Some individuals have the posterior portion of the forewing median band faded or reduced to small white patches</p> |
