Catocala of Michigan

Little Yellow-Orange Underwings: Wingspans: 35-45mm

dulciola; Quiet/Sweet Underwing, wingspan: 40-45mm; A double, black, almost smooth antemedial line (inner line broken only near the costa) with other lines obscure distinguishes dulciola. There is also a dark basal dash on an otherwise plain, light grey forewing.

Little Yellow-Orange Underwings: Wingspans: 35-56mm These tend to be slightly larger on average than preceding group. ** 8876 Catocala micronympha, the Little Nymph Underwing, (wingspan: 35-50mm). John Himmelman image. The usual specimens have grey forewings shaded with green, brown, black and white tints. There is usually a darkened band passing from the costa through the reniform spot to the outer margin. There is high variability with this species. Full size Joe Garris photo of C. micronympha form hero. ** 8877 connubialis, Connubial Underwing, (wingspan: 35-50mm). The forewing is highly variable and there are several different forms: "sancta" Hulst is the typical form and has forewings with white ground colour and sharply contrasting black lines and markings. There is also brown shading between post medial and subterminal lines; "cordelia" H. Edwards is coloured as above but markings are faint; "pulverulenta" Brower has grey-green forewings with faint markings, sometimes none; "broweri" Muller is the melanic form with forewings that are dark green, almost black. The hindwing has a separate anal spot and the outer band ends with a straight cut. Leroy Simon image. ** 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. Tim Dyson image. Catocala grynea, bait trail, Mason, Ingham County, July 12, 1996, Harry King ** 8865 praeclara; Praeclara Underwing, wingspan: 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. Catocala praeclara, Michigan, Cindy Mead ** 8867 Catocala blandula; Charming Underwing, wingspan: 40-50mm. The pale basal area of the forewing distinguishes mira from blandula (dark brown) and crataegi (black). The forewing has dark contrasting lines as in crataegi. There is also considerable brown in the subterminal area and the subreniform spot is very conspicuous and usually brown. A light area runs obliquely from the costa to the subreniform spot. The hindwing is deep orange and has a complete inner black band. The outer black band is unbroken. Lynn Scott image. Catocala mira; Wonderful Underwing, 40-50mm. Pale basal area of forewing distinguishes mira from blandula (dark brown) and crataegi (black). Forewing lacks dark contrasting lines of crataegi and blandula. There is also considerable brown in subterminal area and subreniform spot is very conspicuous and usually brown. A light area runs obliquely from costa to subreniform spot. There is also a noticeable space along inner margin between antemedial & postmedial lines. Hindwing is deep orange and has a complete inner black band. Outer black band is unbroken Tim Dyson image. ** 8858 Catocala crataegi WO; Hawthorn Underwing, 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. There is also a definite greenish cast to median area. The lower wing has the outer black band, broken near the anal angle, distinguishing crataegi from blandula. Tim Dyson image. ** 8841 Catocala abbreviatella BG; Abbreviated Underwing; 40-50mm. Fw uniformly colored with narrow black lines on anterior half. Brown reniform spot ringed with black. Hw outer black band abbreviated and then continued with dot. Inner black band terminates well before im. Similar species: C. nuptialis solid black reniform spot. C. whitneyi broad dark triangles mid fw. ** 8844 amestris; Three-staff Underwing; wingspan 43-50mm. There is a large pale patch near the apex. In form "westcotti" the hindwing outer black band is complete. In other moths, the band is broken as in abbreviatella. Hindwing ground colour is usually deeper yellow-orange than in similar species. Leroy Simon image. ** 8843 whitneyi TM; Whitney's Underwing, wingspan 45-50mm. Catocala whitneyi is similar to abbreviatella Grote, and nuptialis Walker, but generally flies later in the season where the species overlap. The two black wedges/triangles on the forewing, one over the reniform spot and the other just outside the antemedial line, distinguish whitneyi. Gerald Fauske image. ** 8775 antinympha; Sweetfern Underwing, wingspan 45-55mm. The very dark grey, almost black, forewing ground colour distinguishes antinympha. There is some brown shading in the subreniform spot and also just outside the postmedial line. The hindwing is amber to pale orange. There is also the form multoconspicua Reiff, 1919 with a pale, almost white subreniform spot. Tim Dyson image. ** 8772 clintoni; Clinton's Underwing, wingspan 45-55mm. The black basal dash distinguishes clintoni from illecta and abbreviatella, both of which lack the dash. Vernon Brou image. ** 8772 gracilis; Graceful Underwing, wingspan 40-45mm. Gracilis closely resembles sordida but the hindwing loop is not complete in gracilis as it is in sordida. Gracilis also tends to have a darker inner margin and there is frequently (99% of the time, Dale Schweitzer, via Joe Garris), but not always, a basal dash. Sordida never has the basal dash. Catocala gracilis, Pinkney, Michigan, (1968 JLS) ** 8776 coelebs; Old Maid Underwing, wingspan 54-56mm. The gray region from the forewing pm line to the outer margin readily distinguishes this species. The fringe is gray on the lower wing from the brief orange dash at the hindwing apex to the anal angle. Tim Dyson image. ** 8777 Catocala badia; Bay Underwing, 50-60mm. Fw buff-brown, deeper brown in basal area and within pm line; paler beyond pm line; lines faint, barely traceable. HW yellow-orange with black bands; often with terminal yellow-orange line at base of fringe. NH. specimens may appear transitional to coelebs, having the sharp bend of upper part of pm area and more distinct lines of that species."

Midsized Orange-Salmon-Red-Scarlet Underwings: Wingspans: 50-72mm ** 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. Catocala ultronia form celia, Mason, Ingham County, July 7, 1994, Harry King. ** 8779 serena Serene Underwing. Head, collar and abdomen are brown while thorax is grey. Am and pm lines are thin but very dark and distinct on an otherwise drab, almost uniformly olive-grey forewing. Black marginal band of the lower wings is indented at the center, and relatively narrow, deep yellow median band parallels this indentation. Basal hairs are brown. Catocala serena courtesy of Carroll Rudy, July 28, Calumet County. #8778 Catocala habilis; 55-65mm. Note large "M" on thorax and "pork chop" shaped, light coloured subreniform spot that becomes very dark in its constriction at juncture with pme line. Pm line narrow but dark and distinct, outwardly lined with narrow suffusion of white scales, followed by broader band of brown scales, and then another broader suffusion of white scales up to very regular dentation of subterminal line. There is always significant "bleeding" of yellow-orange to salmon scales into hw fringes. Large reniform spot has brown center, faintly edged with black, then white, then black again. Joe Garris image. #8817 briseis; Briseis Underwing; 60-70mm. Forewings are predominantly a mottled dark-grey-brown with some lighter areas 1) between postmedial and subterminal lines, 2) at very base of antemedial and postmedial lines along the inner margin, and 3)over the subreniform spot running diagonally toward the costa. The postmedial lines do not have greatly elongated and sharly pointed "teeth" near apex. The hindwing fringe is white and unbroken and inner black band (fairly even) reaches inner margin. Tim Dyson image. Catocala briseis, UMMZ #8795 Catocala palaeogama ; wingspan: 60-70mm Subreniform spot is closed, does not approach pm line, and is smaller than in C. habilis. All forms have characteristic orange, heavily barred fringe to apex, and irregular bands on hws. Hw basal median area is heavily suffused with dark brown to black scales. There is dark bar in outer half of median area, paralleling inner margin halfway between inner margin and light, closed subreniform spot. Joe Garris photo. #8795 Catocala palaeogama form phalanga; wingspan: 60-70mm. In this form, the forewing basal area and subterminal area are very dark against a much lighter background. The dark bar in the outer half of the median area, paralleling the inner margin halfway between the inner margin and the light, closed subreniform spot is especially evident. Joe Garris image. Catocala palaeogama, Pinkney, Michigan, (1968 JLS) ** 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. Jim Vargo image. ** 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. Vernon A Brou image. Catocala innubens, UMMZ Catocala innubens form scintillans, Mason, Ingham County, bait, July 9, 1994, Harry King. Catocala innubens form hinda, Mason, Ingham County, bait, July 11, 1994, Harry King. ** 8851 Catocala coccinata; Scarlet; 57-70mm. There are usually diffuse basal and anal dashes on an otherwise light grey, mottled fw. Hindwing fringe is white (often with some salmon scaling) and is heavily checked. I find "tooth" just below pair of very elongated "teeth" is much reduced and is quite rounded, usually allowing considerable room for lighter patch of scales. Dark bar crosses thorax. Reniform spot tends be to light, often with greenish cast. Joe Garris image. ** 8840 Catocala illecta; Magdalen Underwing, wingspan: 60-70mm The forewing pattern and colouration is much like that of concumbens, pale grey with faint black lines. Hindwings are light yellow and the irregular inner black band terminates well before the inner margin. James K. Adams image. Collecting Catocala illecta Larvae Kalamazoo, Michigan, Harry King

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. ** 8782 Catocala flebilis ; Mournful Underwing, wingspan: 54-65mm. Diffuse black band runs from basal area to outer margin just below apex, interrupted by pale grey subreniform spot. Reniform spot is filled with brown, additional brown outside the postmedial line. No anal dash as there is in angusi. ** 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. John Himmelman image. Catocala residua, the Residua Underwing, (wingspan: 60-73mm), yes, is distinguished from Catocala obscura by the grey hindwing fringe of residua. Catocala obscura has white to off-white fringe and tends to be less common in northern portions of its range. The forewing subterminal line/area of Catocala residua tends to be pale as is its open, elongated subreniform spot. Like C. obscura it is otherwise devoid of significant markings except for the hint of a dark bar running from the basal area through the reniform spot to the outer margin just below the apex. Catocala retecta; wingspan: 60-75mm Note the light coloured, elongated and open subreniform spot which interrupts the dark, diffuse ark running through the center of the wing from the basal area (body-wing juncture) to the forewing apex. The center of the reniform spot is brown and there is a brown area just below the costa running to the inner margin just outside the pm line. The off-white hindwing fringe is only lightly checked along the wing veins. Catocala rectecta, Pinkney, Michigan, (1968 JLS) Catocala dejecta, (wingspan: 56-73mm; Hodge #8790). The Dejected Underwing is quite similar to Catocala retecta. Here the light coloured subreniform spot is also open, but it has a distinct "pork-chop" shape and separates a much darker median area below the subreniform spot from a very light area to the costa above the spot. The lower quarter of the submarginal area is also much darker in C. dejecta than in C. retecta. Full size Joe Garris photo. Catocala dejecta, female, Shaw lake, Barry County, Michigan, July 18, 1986, Harry King. ** 8784 obscura; the Obscure Underwing, (wingspan: 60-72mm), has dull, grey forewings, usually void of any significant dashes or streaks, providing for easy identification. The antemedial, median and postmedial lines of obscura are faint and the subterminal line region is only slightly paler than the rest of the forewing. The hindwing fringe is off-white and lightly checked on the veins. Joe Garris photo. ulalume; Ulalume Underwing; 62-75mm. Fw colouration is a mottled light to dark grey with no strongly contrasting lines, dashes or bars. At the inner margin the antemedial line ends with in a very light coloured crescent. The subrenifrom spot is also light coloured and "comma" shaped. The hindwing is black and the fringe is pure white with thin, sharp (pointed) checking. ** 8794 Catocala lacrymosa; Tearful Underwing, wingspan: 60-82mm The forewing is highly variable with a mixture of black, brown (wing tips and outside postmedial line) and dark grey scaling. There are usually whitish crescents, along the inner margin at the base of the antemedial and postmedial lines. The hindwings are black with white checkered fringe, turning black near the anal angle. ** 8783 Catocala angusi WO; Angus' Underwing, 60-74mm. Dark dashes/streaks in basal & anal areas. Reniform spot: light brown filling. Hw fringe black except for white region at apex. James K. Adams image. ** 8783 Catocala angusi WO; Angus' Underwing, 60-74mm; Dark dashes/streaks in basal & anal areas. Reniform spot: light brown filling. Hw fringe black except for white region at apex. Form lucetta has broad black band from basal area to om, broken only by reniform & subreniform spots. James K. Adams image. ** 8791 Catocala insolabilis; Inconsolable, wingspan: 65-75mm The forewing is light grey with blackish shading along the inner margin. The antemedial and postmedial lines are thin. The hindwing fringe is very narrow and grey, becoming whiter toward the apex. The ventral surface clearly distinguishes insolabis, being almost completely black except for some white in the basal area. Vernon A. Brou image. Catocala insolabilis, UMMZ ** 8792 Catocala vidua; 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. ** 8793 Catocala maestosa WO/BG, Sad Underwing, wingspan: 78-98mm Maesotsa is quite similar to, although usually larger than, vidua. Both have the dark arc from the costa, above the reniform spot, to the outer margin just below the apex. Maesotsa, however, lacks the dark bar, found on vidua, parallel to the inner margin. The reniform spot is brown and there is brown shading just outside the postmedial line. The hindwing fringe is white, narrow and heavily barred.

** 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.
