Wingspan.
Flight Time.
Description. Very variable, occurring in markedly different forms. FW in typical form (sancta Hulst) white, with strongly contrasting black lines, blackish splotches, and prominent brown shading between pm and st lines. In form "cordelia" H. Edwards (amasia Smith & Abbot), FW whitish, with splotches and shading as before, but lines faint or obsolete. In form "pulverulenta" Brower, FW uniformly greenish gray, with previous pattern faintly discernable, or absent. The form "broweri" Muller is the melanic, with FW entirely deep green-black. HW yellow-orange with black bands; outer band usually sharply broken (with straight edge at break), with separate anal spot. 40-45 mm. H 35: 1 (typical, as amasia). B & Mc 9:19 ("cordelia"), 21.
Similar species. Some specimens may be similar to certain variations of micronympha. The abrupt, straight break in the outer black band of the HW is quite consistent in connubialis,and clearly differs from the usual irregular or rounded break at this point in micronympha.
Range. Southern Canada (Nova Scotia) to Florida and west throughout area.
Status. Generally rather rare, but very local. Perhaps increasing in numbers at present to the northeast in its range (e.g., Nova Scotia and New England).
Larval foodplants. Oaks (Quercus). Reared on Red Oak (Q. rubra) (AEB).
Notes. Moth rests head-down on tree trunks.
