Compiled by Bill Oehlke. Please help me improve the documented accuracy of this page and the linked files by sending data and electronic images to Bill Oehlke.

All photographs I use on my webpages remain the property of respective photographers and are credited to same.

I will do my best to help with identifications if you need/want assistance.

As of April 4, 2010, this page has been further updated as per research data compiled by Larry Gall.

I would like to continue to refine the listings to county levels so images and data (date, location at least to county level, bait, lights) would be very much appreciated. Please send same to Bill Oehlke. All images that I use on my websites remain the property of respective photographers and images are credited as such.

The Identification Keys Diagram should help you understand the terminology I have used in describing the various species.

faustina allusa. unconfirmed White interior outline of terminal line is typical of this species and two jagged upper "teeth" of postmedial line are typical of most poplar feeders. There is also a dark bar a few mm up from inner margin of the forewing. Subreniform spot and area interior and above tend to be lighter. willows and poplars

** 8821 semirelicta; Semirelict Underwing; wingspan: 65-75mm. Fw ground colour white with dark lines and shadings. Diffuse dark bar runs from center of basal area to outer margin a few mm above anal angle. Note regular dentation of st line. Inner black bar on lower wing usually terminates well before inner margin. The form "atala" has forewing that is uniformly grey. Unijuga is usually larger and has less contrasting black lines. Inner black bar on unijuga usually reaches inner margin. Tim Dyson image.

** 8822 meskei TM; Meske's Underwing; 65-75mm. Fws less distinctly marked compared to unijuga, some red-orange at the hindwing apex and just inside the fringe along the outer margin in meskei that is lacking in unijuga. Fw subreniform spot is opened or connected to the postmedian line. The hindwing postmedian band nearly straight, turned in and tapering near anal angle. Tim Dyson image.

Catocala grotiana; Grote's Underwing: 70-80mm: The white outlines outside the postmedial and inside the subterminal lines make this species stand out. The hindwing inner black band is even and relatively thin and terminates well before the inner margin. The fringe is heavily checked and charcoal grey along the inner margin. Hindwings can be orange or red. August until September; willows

Catocala jessica; Jessica Underwing: 75mm: Fw is bluish grey with some brown scaling. Am line is irregular, meets i m almost at midpoint. Pm line has one upper tooth produced, second is much less so. Third is little more than a sharp point on smooth curve to fourth tooth, somewhat produced over opening of large subreniform spot. Reniform spot is double and dark in darker region of median area.

Large Orange-Salmon Underwings: Wingspans: 75mm and larger

** 8801 Catocala ilia; Ilia; wingspan: 65-82mm. unconfirmed Several different forms, most have characteristic white area in and around reniform spot. Diffuse dark arc running from this spot to just below apex. Subreniform spot squarish, concave inner and outer edges and elongated constriction connecting it to pml. White dots near fw om in character with the overall "contrasting" appearance.

** 8801 Catocala ilia; Ilia; form conspicua

In this form the entire reniform spot is heavily suffused with white scaling on an otherwise darker ground colour. Hence the form name "conspicua".

Tim Dyson image.

** 8801 Catocala ilia; Ilia; form satanas

In this melanic form the entire forewing, including the reniform spot is very dark. Hence the form name "satanas".

The dark basal streak is still evident on this form.

Tim Dyson image.

** 8801 Catocala ilia; Ilia; form normani

In this semi-melanic form the entire forewing, excluding the reniform spot, is relatively dark. The brownish, kidney-shaped center of the reniform spot is outlined in white.

The basal streak and subapical arc are still visible.

July until September, probably southeast; oaks

Catocala junctura; Joined Underwing; 67-85mm. Fw usually dark brownish-gray to evenly powdered blue-grey w/o significant markings. Doubled reniform spot often obscure. Thin, slightly darker am, pm lines run from costa to im, not widely spaced at im. Hw salmon/ orange-pink, narrow inner black band turns in sharply, does not meet dark-haired im. May-October; poplars and willows

** 8805 unijuga; Once-married; wingspan: 70-90mm: Catocala unijuga has a fairly wide black inner band (almost reaching inner margin) in hindwing and very distinctive patterning in forewing. Meskei tend to have narrower band and dustier (less distinct) looking forewing. Semirelicta tend to have inner bands that terminate well before inner margins. Also note the very white fringe on both the forewings and hindwings. Carroll Rudy image.

** 8805 unijuga; Once-married; 70-90mm.

Form agatha has a much darker, evenly grey forewing.

Hindwings have some darker hairs in basal area. Note very white fringe on both forewings & hindwings. June to october, willows

aholibah; 80-90mm: Fw is mix of grey and brown, with preponderance of brown in subterminal area. Double reniform spot has diffuse brown outline of inner oval. Subreniform spot is small, distinctly outlined in black, light coloured and does not connect to pm line. Upper two teeth of pm line are elongate and are followed by relatively smooth line til next tooth below the subreniform spot. Hindwing salmon or pinkish.

** 8803 Catocala relicta ; Forsaken, White, Relict; 70-80mm: Considerable variation with regard to black/white concentrations on fws.
Typical specimens have basal and subterminal areas with blackish scales.

Black hws, with brilliant even white inner band and white fringe, are distinctive. June until October, probably N.& E; poplars and willows
