Catocala ultronia form celia. In form celia there is a wide, light grey band separating a dark region along inner margin and a dark patch near the apex. The ventral surface of forewings of all forms has a generous suffusion of orange-salmon scales in the lower half of the median area.

faustina; 58 mm Forewing markings are relatively weak on almost uniform drab grey-brown ground colour. The two middle "teeth" in the forewing postmedial line are relatively short. The hindwing inner band is narrow and truncated well before the inner margin. Black extenssions into white hindwing fringe continue as thin lines along veins. June until October; willows

faustina cleopatra; 58 mm; Head and thorax dark bluish grey; abdomen brownish grey. Primaries dark bluish grey. Transverse lines, reniform and sub-reniform indistinct with some yellowish brown shading on upper surface. Orange to pinkish hw with relatively narrow bands, fringe (unbroken) white on exterior margin, grey near abdomen.

californica; 65mm. Fws dark, gritty. Markings indistinct. Dark, large reniform spot; am and pm lines indistinct. Subterminal line inwardly lined with light scales. Hw fringe white, checked halfway to outer edge with black, black lines on veins extending through fringe. Some orange bleeding at apex. Black median band ends well before im. June until August; willow or walnut??

Catocala hermia; Hermia Underwing: 58-68mm; pinkish: Fw uniform, grey-brown/clay coloured, thin, contrasting medial lines. Distinct large double reniform spot. Large concolourous subrenifrom spot usually open. Hw pinkish red, relatively even, narrow black bands. Inner band ends before im. Fringe white, checked, "bleeding" along outer band, near apex.

irene; Irene's Underwing; 65-75mm. Fw grey brown, darker upper half basal area, around reniform spot, indistinct arc near apex. Sbrnfrm spot lighter, open into pm area. Hw median black band pointed before reaching im. Outer band scalloped near a. a.. Probably southeast; poplars, willows

faustina allusa. 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; 65-75mm FW ground colour is whitish 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. Hw inner black bar usually terminates well before inner margin. The form "atala" has a forewing that is uniformly grey. Unijuga is usually larger and has less contrasting black lines. Inner black bar on unijuga usually reaches inner margin. June until October; poplars and willows

#8817 briseis; Briseis Underwing; 60-70mm: Fws predominantly mottled dark-grey-brown with some lighter areas between pm and subterminal lines, at base of am and pm lines along im, and over subreniform spot running diagonally toward costa. Pm lines lack greatly elongated and sharly pointed "teeth" near apex. Hw fringe white, unbroken; inner black band (fairly even) reaches ima. July-September, probably northern only; willows and poplars

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

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

** 8801 Catocala ilia; Ilia; wingspan: 65-82mm. 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 Tim Dyson image.

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.

Catocala junctura; Joined Underwing; 67-85mm. Fw is usually dark brownish-gray to evenly powdered blue-grey w/o significant markings. Doubled reniform spot often obscure. Thin, slightly darker am and 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 until October; poplars and willows

** 8805 unijuga; Once-married; 70-90mm. Fairly wide black inner band (almost reaching inner margin) in hw and very distinctive patterning in fw. Meskei tend to have narrower band and dustier (less distinct) looking forewing. Semirelicta tend to have inner bands terminating well before inner margins. Note very white fringe on both forewings & hindwings. June to october, willows

** 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

Large Black Underwings (Banded): Wingspans: 70-80mm

** 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

** 8803 Catocala relicta ; Forsaken, White, Relict; 70-80mm: Considerable variation with regard to black/white concentrations on fws. Form clara: basal and subterminal areas predominantly white. Typical specimens have basal and subterminal areas with blackish scales. Black hws, with brilliant even white inner band and white fringe, are distinctive.
