Occasionally the lower wings will be yellow instead of orange.
There is considerable variation in forewing pattern as shown in this specimen from Ontario, courtesy of Lynn Scott, the specimen from Marion County, Florida, courtesy of Leroy Simon and in the three specimens courtesy of Vernon A. Brou at botom.

The forewings are typically gray-brown, with a dark lower margin and a characteristic brown patch near the wingtip.
The hind tarsi have three rows of spines. The outer wing margin (lower wings) is heavily barred with a pure white patch at the apex.

In Concan, Texas, moths have been taken in late April.
Tim Dyson of Ontario, Canada, sent me this nice image copyright of an apparent Catocala "fan". Tim has been using some red wine in his bait (August 14), but "me thinks" the "frog" is happy for other reasons.
Moths come in to lights readily and also to bait.

(Jamaica Bay area of New York) July 6.
The Catocala ultronia caterpillar shows a preference for members of the Rosaceae family: Malus (apple), Prunus pensylvanica (pin cherry), Prunus serotina (wild black cherry), Prunus virginiana (choke cherry), Fraxinus pennsylvanica (green ash), Tilia americana (American basswood, American linden) and Populus grandidentata (Big Tooth Aspen).
ECLOSION:Adults eclose from pupae amongst ground litter or near the soil surface.Usually when adults alight on a vertical surface, they align themselves with bodies vertical (ultronia rest with head down). I wonder if this specimen is trying to take advantage of the horizontal grey mortar line. Image courtesy of Lynn Scott. |
Grey, cushion shaped, sculptured eggs are deposited on tree bark in the fall and hatch the following spring.Note the prominent horn on the fifth abdominal segment. There is a distinct black line on top of head and an oblique black line running (anterior) from base of the slightly enlarged dorsal scoli of eight abdominal segment. Dense and relatively long fringe and body are grey. Image courtesy of David Wagner. |
