Catocala of Florida

Catocala connubialis, Hillsborough County, Florida,
May 10, 2010, courtesy of Ken Allen.

The following is adapted from a list obtained from James K. Adams, Dept. of Natural Science, Dalton State College, Dalton, Georgia. The list is at

http://www.daltonstate.edu/galeps/list%20page%20folder/Noctuidae%20Erebidae.htm

Those species listed from Georgia to Texas or Arkansas have been included to comprise this tentative Florida list.

The list probably contains several omissions. It will be updated and refined as sighting data arrives over the years. Please send images with dates and collecting locales (including county) to Bill Oehlke.

Subsequently I have found a list for the Biodiversity Inventory of the University of Florida Natural Area Teaching Lab and have added some species confirmed by that list for the immediate area and Catocla messalina from nearby.

Rick Gillmore (RG) has corrected this list for Florida and has provided some foodplant information, added to the individual species files. I delisted eighteen species from my original list and added those indicated by Rick.

Rick adds, "C.P.Kimball's book, Lepidoptera of Florida is a good book, but an example of another mistake in Kimball's book is with Catocala vidua. He lists five specimens of C. vidua from Starke, Florida, May 1951. Steve Roman and I found all five specimens in the Florida State Collection in Gainesville, Florida, back in the early 70's. The five specimens were all Catocala maestosa."

I have added Catocala charlottae (now Catocala praeclara charlottae) to the list based on an identification by Vernon Brou.

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.

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

**8878 Catocala alabamae; Alabama Underwing; 30-40mm; Uniform greenish-grey fw may have thin but dark (contrasting) lines or they may be nearly absent (titania); alabamae often with dash in median/anal angle area, missing or nearly absent in titania. Brown shading between pm line/subterminal line. Hw inner black band thin, outer band thick, truncated before being followed by large black dot. Early flight season.

**8878 Catocala praeclara charlottae; Charlotte's Underwing; The upper half of the am line is dark, thick and oblique, and turns in a slightly obtuse angle to the inner margin in a straight line. The pm line is black, thin, but distinct, with a single pronounced "tooth". The reniform spot sggests a figure eight and the subreniform spot is closed but cnnected to the pml with a weak line.

**8878 Catocala amica; Girlfriend; wingspan: 35-40mm
The black postmedian band is absent from the dorsal (upper) surface of the hindwing, but it is present on the ventral surface. Moths come in to lights and to bait.

Catocala connubialis, Hillsborough County, Florida, May 10, 2010, Ken Allen.

Catocala pretiosa Precious Underwing; 40-50mm unconfirmed; This species is quite similar to crataegi and mira, but pretiosa has considerable creamy white colouration in the median area. The lower portion of the basal area is also light, not dark as in crataegi. The inner black band of the hindwing forms a loop and the outer band is broken (not complete as in mira, followed by a dot that tapers to the anal angle.

Catocala pretiosa texarkana Texas-Arkansas Underwing; 40-50mm; The median area is quite light with a wide whitish band paralleling the antemedial line from the costa almost to the inner margin. The subreniform spot is distinctly brown.

The black basal dash distinguishes clintoni from illecta and abbreviatella, both of which lack the dash.

Vernon Brou image.

** 8847 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.

** 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.

** 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.

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 delilah; 58-65; The forewing is gray-brown with prominent black antemedial and postmedial lines. The hindwing is yellow-orange, with a narrow inner black band which reaches the inner margin. There is a large yellow spot at the apex, and the fringe is faintly barred. The underside of the wings is deep yellow with black bands.

** 8851 Catocala coccinata; Scarlet; wingspan: 57-70mm: There are usually diffuse basal and anal dashes on an otherwise light grey, mottled fw. Hw 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.

** 8772 Catocala consors WO; Consort, wingspan: 70mm plus. Fw with irregular am and pm narrow black lines. Dark patch outside the reniform and subreniform spots.

Hw 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 atocala, Underwing, (wingspan: approximately 70-75mm). Similar to agrippina, but reniform is more clearly defined in atocala. Closed subreniform of atocala may be open or closed in agrippina. Distinct basal dash of agrippina females is nearly absent in atocala females. Hw undersurface white areas on agrippina are beige on atocala. Hw bulge (discal spot) on atocala, is not present on agrippina.

** Catocala myristica; slightly smaller than robinsonii, myristica has a browner cell spot and a darker bottom line on the longest extension of the pm line near the inner margin. Probably only in Black Belt on nutmeg hickory. unconfirmed

** Catocala myristica; slightly smaller than robinsonii, myristica has a browner cell spot and a darker bottom line on the longest extension of the pm line near the inner margin.

Reniform indistinct, brown, sub-reniform almost obsolete, lighter than surrounding areas.

** 8793 Catocala maestosa SM, 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.

Large Orange-Salmon Underwings: Wingspans: 65mm, usually 70-95mm

** 8801 Catocala ilia; Ilia; wingspan: 65-82mm
Catocala ilia specimens come in several different forms, but most of them have the characteristic white area in and around the reniform spot. There is also a diffuse dark arc running from this spot to just below the outer apex.
Except in worn specimens and the darkest forms, the white dots near the outer margin of the forewing are in character with the overall "contrasting" appearance of this moth.

** 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.
