The forewing is gray-brown with prominent black antemedial and postmedial lines. The hindwing is yellow-orange, with a narrow inner black band which reaches the inner margin. There is a large yellow spot at the apex, and the fringe is faintly barred. The underside of the wings is deep yellow with black bands.
"AM line thick at costa, gradually becoming thin toward inner margin, or appearing “beaded” due to alternating thick and thin areas; dorsal forewing surface usually evenly brown; dorsal hindwing with bands brownish orange; edges of apical spot on ventral hindwing usually not well defined." David Hawks
"One of the two largest species in the complex, with mean forewing costal margin length 27.1 mm males, 30.5 mm females. The only species similar to C. delilah is C. desdemona. Both are similar in size, with a brown thorax, but C. desdemona has a paler and more yellowish abdomen that contrasts with the thorax. The forewing antemedial line is wide (ca. 2 mm) at the costa in both species, but in C. desdemona it abruptly becomes thin just past the radial vein; in delilah the line becomes thinner gradually. The brown line just basal to the antemedial line is usually less conspicuous in C. delilah. In contrast to C. delilah, the forewings of almost all specimens of C. desdemona are speckled with white or yellow scales, which gives the wings a distinctly gray cast." David Hawks
Subspecies C. delilah desdemona has now (2010) been elevated to full species status as Catocala desdemona.
The Catocala delilah caterpillar feeds on Quercus virginiana Mill. (in Texas and Florida), Q. fusiformis Small (Texas), and Q. laurifolia Michx. (Texas).
