Hey Paul, I'm really surprised that you don't have a drawer full for yourself. Looking at the range map of the species it should be all along the U.S./Canada border at least up until Montana.
I have to admit I am envious of bills drawer of specimens because I have never been able to find relicta anywhere near my area. Bill has said in the past that he has a population near his home. He lives in the center portion of my state which places him about 3 hours south of where I live.
He's very fortunate to say the least. That moth is a gem !!

“Oh well, this is sometimes the way of things when one is dabbling with Catocala.“. Don’t I know it.
Yes, I got one this summer here.....it’s the one at left of the two in row five. I’ve been blessed to have taken them in three locations.....a state park 15 mi away back when I had a permit, a city park 13 mi away where I got the one this year, and my back yard. One boom year I got 60 decent relicta here.......sent many to friends. The rest are from WI with two being from my buddy in AZ. Weather permitting before our coming cool down after some decent rains (we were in a drought scenario), I will head out tonight to try once more. The season is winding down atm.

Just got in. Got 1 innubens form hinda, 1 cara, 3 maestosa, and 1 junctura. We’re gonna get lots of rain and cold temps this week. Unless a good warm up follows, the season may be done for me. It was pretty good overall.
Cerogama is a good find in my book (at least out here) in Illinois. I have only collected in in the far southern counties of my state. only twice at that ! Cara is one of my ALL TIME favorites but, alas I have collected very few here as I have never had one show up at light (of any kind). Have picked up 4 whilst sugaring. Don't use traps either because of the wasps (as you mentioned) and also because I could not check them in any timely manner due to work and family responsibilities.
cara is one of the most bait-heavy species I've encountered, with concumbens being very much light only. I think I've seen a cara at light maybe once and concumbens at bait maybe twice. These two species are also never really found tapping, but I've seen cara under eaves by day like amatrix is fond of doing. I have found few few species that can be tapped, baited, and lighted with equal frequency. I have strong bait and tapping species like palaeogama and ilia be only sporadic or hit-and-runners at light. A common daytime species like epione can be common at light but never comes to bait. I think my nominee for the best jack-of-all-trades is C. vidua which I've gotten at all three commonly but light seems to be it's least favorite.
I've been busy with school and not added any Catocala for awhile. Here are the closer photos that were requested. I would appreciate opinions on whether I have praeclara or alabamae or both. Also, the smallest one with the junctura is luciana. Thanks!
In looking over tim's close up photo's I find C. amica and lineela both tough to tell apart. They are similar in size, hindwings look the same, and only the forewings appear different. Although, tim only shows (or has one amica). These little ones it seems can be tough too...
I'm not doubting tim's determination of these two. I suppose those light gray patches on the forewings of amica do make it a standout from lineela (after looking at it again)!
Thank you Rayrard for your thoughtful expertise. That is a very good observation regarding that large reniform spot on that top specimen. It is noticeably different than that of the middle specimen. I noticed that both specimens have a rather hook shaped marking below the reniform spot but, clearly the color and size of the spots are different.
Although my picture does not show it the bottom specimen does have gunmetal colored four wings; that is they have a bluish sheen overlaying the whole of the gray four wings
Rayrand, the retecta ( middle specimen) was collected in Sauk Co., Wisconsin. Looking at a county map of Wisconsin it is one of the southwest counties of the state.
There is a lot more tree cover and wild spaces in Wisconsin as compared with my state of Illinois. , If that is a little far north for the species then I suppose he is fortunate in having caught it since, it may well be at the extreme reach of its range there.
That is a nice collection of Catocala. I only collect fourteen (14) species in NE Ohio to date.
I also collected four (4) species in South eastern Coloroda, two (2) spieces in the Fort Morgan/Roggens area of Colorado. One species in NW Kansas and another in Oklahoma.
I visited Killdeer Plains Wildlife Area (Killdeer WA got a new name for 2020, it is now Killdeer Plains WA) this AM and checked my Bait Traps and four Light Traps I set out last night. The Bait Traps had numerous but worn Catocala. I had numerous females but not a keeper in the lot. I was inundated with Apamea helva, Resapamea stipata and Lithophane semiusta in the Bait Traps. All were immaculate. The Resapamea stipata was new for me.
I also Baited a number of trees. This AM I lifted tree bark and collected several winter/cold weather moths including several Seraglea.
I stopped at "The Coffee Shop" in Little Sandusky on my way home. I saw a moth on the window on the side of the Coffee Shop. A very nice Eupsilia devia. I also found a Lithophane querquera, also in excellent condition. Driving home on US30, I drove through a down pour. I actually stop under an overpass and sat until it slowed down.
I also stopped at the Sears Wood SNP west of Bucyrus. Although collecting is not permitted, just walking through the ancient forest was worth the stop. I may apply for a research permit and see what is there.
I designed a Light Trap and a method of deploying the Light Trap in the Canopy. I used it several times in 2018 while conducting a Lepidoptera Survey in Central Indiana. The Sears Wood SNP might be an excellent place to try it out again.
I will ask the question again. Has anybody ever surveyed the insects in the Canopy?

Leptraps, I imagine very, very few collectors, hobbyists, or enthusiasts have ever endeavored in any sort of canopy collecting or "surveying" --- not that its a bad idea. It just requires more time and effort to set-up a rigging (using ropes, pulleys, etc.); to get a trap up into a suitable canopy environment. Quite frankly, most collectors would just a soon bounce their light rig, bait trap, light trap, or what have you out onto an earthly (terrestrial) plane for their "small game" hunting activities.
However, I can tell you that in the late 1980's and 1990's an entomologist associated with the Smithsonian Institution was down in Peru (and perhaps some other countries) doing Canopy "fogging". His name is Terry Irwin and he perfected a method of mass surveying of a given locale using a "cattle barn" fogger of the (industrial use) type.
A cattle barn fogger as you probably know is a man portable "pyrethrum fogger". It has a thick strap which you sling over one shoulder as the device rests next to your hip. It has a 4ft. long barrel through which the pyrethrum flows and is converted into a gas. Its a "terribly" loud beast which is gas powered. I suppose much like an "amped-up" leaf blower...
Anyway, terry and his team would hoist one of these weighty "bazooka's" into the canopy of a large rainforest tree (using a rope and pulley system). Beneath, the device they would put in place some manner of sheeting (either thin tarps or king size bedsheets); to cover as much of the area beneath the tree as possible; allowing only "channels" wide enough to walk through. Once, all was in place the team would wake very early the following morning (like 3 a.m.) when the air was heavy with moisture and still.
Then the fogger would be fired up and the ensuing pyrethrum fog would "hang" in the canopy where its "knockdown" effect became readily apparent. An insect "rain" (deluge) would very soon be upon them. The sheeting caught the ensuing biomass and within 15 minutes or so a contingent of workers were collecting up and / or bottling up everything possible. Using this method, he was able to do a rapid assessment of the localized fauna. Enough work really for the coming years...
One article which I read reported that he had found nearly 40 species of ant on just ONE rainforest tree ! Based upon several such surveys which he conducted he theorized that our estimates of possible insect species is far TOO low. He thought that perhaps as many as 10 million species of insect might be possible based upon his incredible diversity findings.
I don't know if such surveying has continued into the decade of the 2000's but, YES canopy surveying has been done with great success by the Smithsonian team of entomologists.
