Catocala neogama euphemia (wingspan: 75 (ER)-90mm), flies in Arizona and New Mexico.

At one time this moth was treated as a separate species, euphemia.

Forewing ground colour is charcoal grey, often with a bluish tinge.

The am line is thick and dark along the costa and extends in three more narrowly lined lobes, the upper two of which are notched, toward, but not reaching the midpoint of the inner margin. The pm line has the two upper teeth elongated, followed by a much short tooth and then a longer tooth along the extended line of the subreniform spot. Below the line is an elongated rounded tooth followed by a much shorter rounded tooth along the inner margin.

The concolourous to slightly lighter subreniform spot is "pork chop shaped", but closed (approximately, usually) with an extended tail joining the pm line.

The thorax is grey, and the abdomen is a golden orange.

The hidwing ground colour is yellowish-orange, with a rather large yellowish orange apex intruded by a black vein extension. The fringes are also yellow-orange and are divided by black along the veins.

Larval Food Plants

Listed below are primary food plant(s) and alternate food plants. It is hoped that this alphabetical listing followed by the common name of the foodplant will prove useful. The list is not exhaustive, although some species seem very host specific. Experimenting with closely related foodplants is worthwhile.
