The following thumbnail table displays the Catocala species that are generally recognized as flying in Massachusetts and/or species which I feel are likely to be found in Massachusetts.

Please help me improve the documented accuracy of this site by sending sighting data (date and location, bait, flowers, lights) and electronic images to Bill Oehlke. I will do my best to identify specimens if you need/want assistance. All images that I post on my websites are credtied to respective photographers and remain the property of the photographers.

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.

Many thanks to Dave Small of Athol, Worcester County, who has sent many images and data from his locale. I am able to refine some of my descriptions, notably Catocala praeclara, based on his efforts.

Many thanks also to Barbara Spencer, Josua Rose, Betsy Higgins and Brian Klassanos who have also sent images and data for Massachusetts.

Many thanks to Ray who provides the following images of a small (65mm) Catocala unijuga from northwestern Massachusetts.

** 8806 Catocala parta; Mother Underwing, 70-85mm. Black dashes in basal, subapical, anal areas help to identify this species. Hws may be yellow to yellowish-orange but more often are salmon-red. Note face-head-like markings on thorax. Hw: first (nearest apex) black protrusion into white fringe "noticeably" larger than others.

** 8798 Catocala neogama; 70-85mm. Brown head, thorax, larger size compared to C. palaeogama. Neogama tend to be smaller than subnata, have darker grey brown fws with more pronounced markings. Examination of hind tibia needed for id. Neogama's: flattened, unevenly, sparsely spined; subnata's: cylindrical, spines dense, uniform in distribution.

** 8797 Catocala subnata; Youthful Underwing: 75-90mm. Fws greyish white with blue-grey and light brown scales, usually with hws brighter yellow than those of neogama. Neogama usually have basal dash; absent in male subnata, but present in females. Magnification of hind tibia needed for id: subnata: cylindrical hind tibia; neogama: compressed or flattened hind tibia. subnata: ventral surface of tibia densely covered with evenly distributed spines; neogama: ventral surface of tibia sparsely covered.

** 8796 Catocala nebulosa ; Clouded; 75-86mm. Prominent dark brown upper-half-basal patch extends to and ends at am line. Apical area also tends to be brown, much darker than median area but not as dark as basal patch. Anal angle has darker brown scaling. Pm line: distinct near costa and inner margin, but becomes weak between them. It meets inner margin in relative close proximity to am line. Closed subreniform spot: large, connects to pm line via thin line. Maybe ??

** 8804 Catocala marmorata ; Marbled Underwing; 85-95mm. Dark fw arc from costa through reniform spot to outer margin just below apex distinguishes this species from other "pinkish-red" underwings. Subrenifrom spot light, bordered inwardly above by white patch, connected to pm line by line rather than being open. Unlikely ??

Large Pink Underwings: Wingspans: 70-95mm

** 8833 Catocala concumbens Sleepy Underwing or Pink Underwing (wingspan: 60-75mm). This brown thoracic collar is quite evident in this image as is the interruption in the pm line by the open subreniform spot. The white hindwing fringe is only lightly checked on the wing veins. The vibrant pink bans are distinct in colour and also in their relatively smooth contour.

** 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 barely visible. No distinctive bars, dashes. Two upper "teeth" on pm line are thin, long. Hw bands: pink. Heavy black checking on off-white hw fringe. Relatively thick black median band of hw almost reaches inner margin which is usually heavily adorned with dark hairs.

** 8834 amatrix Sweetheart Underwing; 75-95mm: Very skittish, frequently hides in caves, under bridges, under tree bark, etc. by day, resting with head down. Hw patterning; colouration similar to that of C. concumbens, but large size (75-95mm) & dark bar running from basal area to just below apex distinguishes C. amatrix.

** 8834 amatrix form selecta Sweetheart Underwing; 75-95mm: Very skittish; frequently hides in caves, under bridges, under tree bark, etc. by day, resting with head down. Several forms, including selecta (left) which lacks dark bar on forewing. Hesseli: melanic form; pallida: very pale form.

** 8834 amatrix form hesseli Sweetheart Underwing; 75-95mm: Very skittish, frequently hides in caves, under bridges, under tree bark, etc. by day, resting with head down. Melanic form hesseli is very dark; displays dark basal hw hairs.
