minuta yes

** 8864 Catocala grynea ; Woody Underwing, wingspan: 40-50mm

The forewing is a dull greenish grey with orangey-brown shading along the inner margin. The antemedial, median and postmedial lines are quite faint.

Praeclara is somewhat similar but has a break in the brown shading between the am and pm lines. Praeclara also has a paler orange hindwing color.

** 8865 praeclara; Praeclara Underwing, (40-50mm); The forewing is a pale greenish-grey with considerable contrasting brown shading beyond post medial line.

There is a black basal dash very close to the inner margin and another dash, higher up in the median area.

Note the contrasting shapes of the reniform and subreniform spots. Tim Dyson image.

** 8858 Catocala crataegi unconfirmed; Hawthorn Underwing, wingspan: 40-50mm Determination is based on dark (black) shading in forewing basal area continuing along inner margin to anal angle and brown shading beyond postmedial line. Definite greenish cast to median area. Lower wing has outer black band, broken near anal angle, distinguishing crataegi from blandula.

** 8857 Catocala ultronia; Ultronia Underwing, wingspan: 50-63mm.

Fws typically gray-brown, with a distinct and very dark inner margin and characteristic light brown patch, underscored by very dark arc, near wingtip. Underwings can be yellow to orange to salmon.

** 8857 Catocala ultronia form lucinda; Ultronia Underwing, wingspan: 50-63mm.

In form lucinda most of the forewing is bright grey.

On all forms there is extensive orange-salmon colouration on hw ventral surface, and there is a dark discal lunule.

Catocala ultronia, form nigrescens, the Ultronia Underwing, wingspan: 50-63mm. In the melanic form nigrescens, the dorsal forewing is very dark. Even darker subapical arc, basal dash and dash near anal angle are still visible. Dark basal hairs on hindwing. Harold J. Vermes slide, used with permission from his son.

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.

** 8770 Catocala innubens; Betrothed; 55-72mm. Forewing is mottled with white, grey and brown, and subrenifrom spot tends to be lighter in colour, although it is sometimes obscured by an indistinct blackish bar which runs from middle of basal/thorax connection to just below much lighter apex at outer margin.

** 8770 Catocala innubens form scintillans; Betrothed; 55-72mm.

In form scintillans most of the basal area (all but lower third) and all of the median area of the forewing is dark reddish brown. The area outside the pm line is grey.

Solid Black Underwings: Smallest to Largest, Similar Species Paired

** 8781 judith, Judith's Underwing, (wingspan: 45-55mm), is one of the smaller "black" underwings.

The forewing is a uniform light grey with thin and only slightly darkened antemedial, median and postmedial lines. There are no darkened dashes (slight anal dash) or transverse lines. The reniform area is slightly darkened while the area just before the subterminal line is a bit lighter. Note absence of hw white fringe. Joe Garris photo. unconfirmed

** 8782 Catocala flebilis, yes; Mournful, wingspan: 54-65mm. Diffuse black band runs from basal area to outer margin just below the apex, interrupted by a pale grey subreniform spot. The reniform spot is filled with brown and there is additional brown outside the postmedial line. There is no anal dash as there is in angusi. The hindwings have white fringe. J. K. Adams image.

** 8773 Catocala epione , yes; Epione Underwing, wingspan: 55-65mm

The pm line is squared and has a brown band and then a light band just outside the line.

The hindwing is black with pure white fringe with no barring.

Catocala residua, Residua Underwing, yes, (wingspan: 58-73mm), Distinguished from C. obscura by grey hindwing fringe of residua. C. obscura has white to off-white fringe, tends to be less common in northern portions of its range. Fw subterminal line/area of C. residua tends to be pale as is its open, elongated subreniform spot.
Devoid of significant markings except for hint of dark bar running from basal area through reniform spot to om just below apex.

** 8792 Catocala vidua, yes; Widow; wingspan: 70-80mm
The ground colour of the forewing is light grey. There is a distinguished dark arc running through the top of the reniform spot to just below the apex. There are heavy, dark anal and basal dashes, connecting to a dark median bar, running parallel to the inner margin.
The am line is thick and black in its upper half.
The reniform spot consists of two almost concentric irregular ovals. The subreniform spot is light, open, but constricted as it meets the pm line. The hindwing is black with broad, white fringe, only lightly interrupted. Marie Winn image.

** 8802 Catocala cerogama; Yellow-Banded; 70-80mm. Several different forms. Pm line distinct, dark and has elongate pair of projections. Pm and am lines meet inner margin in relative proximity. Closed subreniform spot lighter than surrounding areas, shaped a bit like an arrowhead with point toward body. Hws are distinctive. Jean-Benoît Duval image.

** 8802 Catocala cerogama; Yellow-Banded; 70-80mm.

Form ruperti: Forewings are almost uniform grey-brown with white scales outlining subterminal line.

The hindwings are distinctive. Tim Dyson image.

** 8802 Catocala cerogama; Yellow-Banded; 70-80mm.

Form bunkeri: Forewings are dark in median and basal areas. Hw golden band is reduced in thickness. Basal hairs are brown instead of yellow.

The hindwings are distinctive. Tim Dyson image.

palaeogama yes
neogama yes
marmorata yes
briseis yes

** 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".

** 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.

** 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.

** 8771 Catocala piatrix ; Penitent, wingspan: 68-84mm. Fw: light-colored band/bar extending from light coloured, triangular subreniform spot along the am line to the costa. Brown, kidney-shaped reniform spot surrounded in pale grey, outlined in black, usually with distinct black along wing veins in a dark area outside the reniform spot.

Hw: fringe lightly barred;s lighter in color than deeper orange on rest of wing.

** 8832 Catocala cara; Darling; 70-85mm. Note deep maroon almost purple cast to fws, mixed with very pale green. Lower half of am & pm lines is barely visible. There are no distinctive bars or dashes. The two upper "teeth" on the pm line are thin and long.
The hindwing bands are pink. There is heavy black checking on the off-white hindwing fringe. The relatively thick black median band of the hindwing almost reaches the inner margin which is usually heavily adorned with dark hairs.
