Catocala of Wyoming

Catocala relicta, form "clara", courtesy of Tim Dyson copyright.
This tentative checklist has been compiled by Bill Oehlke.

The following Catocala species are speculative, based on what I think are reasonably accurate lists for Montana (M), Colorado (C), Idaho (I) and Utah (U). Those species followed by (M/C/I/U) are believed to be in Montana, Colorado, Idaho and Utah, and are therefore expected in Wyoming.

Please report sightings to Bill Oehlke. If you send electronic images, I can probably do the ids or find someone who can.

aholibah yes (M/C/I/U), June until October; oaks
amica yes, probably just eastern Wyoming

briseis yes (M/I/U); July until September, probably northern only; willows and poplars
californica possibly, no confirmed reports western (M/I); June until August; willow or walnut ??
grotiana yes (M/C/I/U); August until September; willows
hermia yes (M/C/I/U); August until September; poplars and willows

** 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.
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.

irene yes
junctura yes (M/I/U); May until October; poplars and willows
neogama probably (M/I/U);
parta probably (M/C/U); July until October; poplars and willows
relicta yes (M/C/I/U); June until October, probably N.& E; poplars and willows
semirelicta yes, northern (M/I/U); June until October; poplars and willows

** 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.

** 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. June until October.

** 8803 Catocala relicta ; Forsaken, White, Relict; 70-80mm: Considerable variation with regard to black/white concentrations on fws. Form phrynia: evenly dusted with grey over entire forewing. 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, poplars and willows

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

** 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.

unijuga probably (M/C/I/U); June until October, willows
