Is C. residua the correct I.D. for this one? Attachments:

Going up to Bayfield, WI this coming weekend. (Lake Superior area) Bringing the moth bait & MV light along. Maybe we can find a stand of white birch or aspen to find some C. relicta.

I received a report that over 163 Catocala relicta were captured in Eau Claire County, Wisconsin, the last two days, mostly at bait traps. You should be able to get them now in Wisconsin wherever there are good stands of poplar/aspen. I suspect those hosts are plentiful in Bayfield County, WI. Bill Oehlke

I envy you Catocala collectors up north. We don't have nearly as many species in east TX. C. ilia is the only species that is common here, at least from my experience. I visit MN occasionally. What species are found there?

Driving up to Minneapolis today for business & stopped at a rest stop just south of Black River Falls, WI & found 4 C. relicta on trees at the edge of the woods. Luckily I had my net & killing jars with me. I had to call home & tell my boys what I had found for them. They were very excited with the news. Rest areas along highways have always been a good area to find insects.

Wow--in my backyard (an oasis of trees in the middle of cornfields in LaSalle Co.) in tonight's first hour-and-a-half, I got: 4 Catocala relicta (two were form phrynia and one form clara) 1 Catocala unijuga1 Catocala briseis----which I have never seen here before and only my second. The first was from WI. I'll post pics later on of my IL August action(here and two other locations) when they come off the boards I thought the night was too cool, but the moths didn't. Boy, does sugaring ever work grrrrrreat. This last weekend I travelled to north central WI for a night of lights and sugaring. It was very cool. No light action, but got 1 C. relicta with sugar slop. This was in Waushara Co. As cool as it was, I was lucky indeed to nab the one.

My Catocala of North America page is at www.silkmoths.bizland.com/catocala.htmlThere are pictoral checklists there, via the links, for every US state that has Catocala species. As far as I know there are no Catocala reported from Hawaii or Alaska. The other forty-eight states do have Catocala species. Because of the reference material coverage on Catocala, many people think of them as a northern (northeastern) genus with moths flying in the fall. In many of the southern states there are large numbers of Catocala species, but they are often on the wing in the spring and summer months before the cooler weather sets in. As far as I know all Catocala species are single brooded. The eggs are the overwintering stage, and the larvae hatch as soon as it is warm enough in the spring for the trees and bushes and other host plants to support foliage. The moths usually emerge 3-5 weeks after pupation (smaller species developing more quickly). Thus there is a much earlier flight season in the more southerly states. I have 67 species listed for Texas, some from specific regions of Texas as opposed to throughout the state. I have 33 species listed for Minnesota. I am always interested in updating the websites with sigthing data (date, location, wingspan, bait or lights, elevation, etc.) and digital images. I do prefer not to post just data, unless I can also see and post the respective digital images. Many of the Catocala species are difficult to id. I make exceptions when I know the data is from experienced collectors. To Bill Garthe: I have just updated LaSalle County, Illinois page to include briseis, at www.silkmoths.bizland.com/ilLaSallecat.htmBill Oehlke

So are they not double brooded in Florida? Catocala to me are a cool season moth, we see them first thing in the spring and last thing in the fall, but not much if at all in between. I swear that they are double brooded here but not being terribly interested in them I may be mistaking different species. I have sugared out of curiosity of course. Do they have an astonishingly long larval stage, 4-5 months or more? I guess I have a new project!

I have heard/read speculative reports that maybe Catocala ilia is double brooded, but I do not think anyone has documented that, and I would be surprised if it is true. I have never received an image submission of an ilia larva from summer months from one of the southern states, but I have received them often enough in the early spring to know that people do encounter them. I would not be surprised to learn that the adult moths mights estivate during summer heat and reappear later in the season (like mourning cloak butterflies), nor would I be surprised to learn that pupal stage in southern states might be prolonged during hot summer months, but I think more likely there is just a single brood each year no matter where one is located. It is interesting that this genus is only found in the northern hemisphere. There are some very beautiful species in Japan, China and Europe, but nothing south of the Equator, not even close, to my knowledge. Bill Oehlke

Hmm... that is interesting. I am going to have to try to rear some here to see what happens. They are definitely around as early as February-March in my area and then as late as October-November. It never occurred to me that these could be the very same adults. Seems very long lived for an annual moth but wouldn't surprise me in the least considering the range of habits in just Lepidoptera. I would say that I have encountered only one or two adults during summer months here (can be almost half the year some years, from May to September, even April to October during warm phases), they clearly do not like our summer temps in general. Hemileuca, which are not supposed to be double brooded ever I think, will definitely produce two generations here although the second is only partial with the remaining ova overwintering as would be expected. Now I'm very intrigued and will make a goal of trying to investigate over the next year or two. Any idea what happened to them in the southern hemisphere? More commonly we see divides where oceans fall, not north to south so that is very interesting indeed. Wow, I think I am becoming a Catocala convert. Always after Sats of course. Nothing is better, not even all those garish rare Papilio the rest of you guys go crazy over

Bill, there have been a couple of species recorded in Mexico. Check out Biologia Centrali-Americana. Also, Southern Illinois is a very good spot to collect Catocala's. When I could collect at Bald Knob Cross, I would take away as many as 100 specimens and 15 species, including Catocala atocala, which is not very common. Jeff Prill

Yes, that Bald Knob spot was a gold mine ineed. Too bad the situation is what it is...legal battles over who has control etc. When those lights were on, so also was the collecting. Maybe they'll work out the kinks and someday those big ole lights will again light up the Shawnee Nat. Forest for miles around.
Catocala atocala is a gem. I never saw one there, but surely think they would be if it was what it was.
