This "orange form" does pop up now and then. I'm guessing maybe 1 in 1000? I don't know what causes it, but they fly with normal polyxenes, so I'm guessing it's not environmental.

Paul & Mothman55- your personal observations are invaluable, keep posting!

In "Butterflies of Viginia" 1953(?) Clark & Clark went off-topic and delved into many pages on forms and ranges and flight periods found throughout eastern North America. For the most part, there has been no significant effort to add to that study- most of what we know is by-product of specific study (e.g. the description of appalachiensis).

About Tigers in the Toronto area, both Wang and Schmidt have published papers that discuss the ranges of glaucus, canadensis, and MST, including maps. I've posted links in this thread somewhere in the past. They are, of course, not comprehensive, and the range of MST (at least) is fluid. But the Canadians do have a far better view of the range of the three taxa than can be found for NY or anywhere in NE USA.

So I'd urge everyone who's interested to offer observations of any sort concerning Tigers, and not just in the east, there are "issues" in the west, and in the US south.

.......................

25 May 2024 I went up near the Lake Ontario shoreline to search for small Tigers that I believe a hybrid between Spring Form and canadensis. Hiking through some real tough deciduous regrowth for hours I saw nothing. Only when I got back in the truck did I see one, flying high along the forest edge as they do. Then garbage weather came in, and continues through today 5/28.

Observed 1, captured 0.

I had an aberrant female a few years ago, also with heavier than typical black markings.

Yes, she is on the spreading board now. Just as I was about to sweep the net, a male came and chased her to the other side of this huge lilac stand.I had to search for a few minutes as there were many males around. Finally found her again and made no mistake this time.

That's quite an incredible capture of a VERY unique female.

I have never seen anything quite like that in all my life !

"Proboscis case" in Sphingidae pupae (continuation)

by lamprima2 » Sun May 26, 2024 4:09 am

A while ago, I asked Insectnet members if something was published on the
structure and function of Sphinginae pupae's maxillary loops (aka "jug handle”). There was no reply. I contacted a few specialists in this area. One of them replied: "If you would look inside, you will see that the galeae extend from the head into the loop, then the galeae bend sharply back and turn back to the head of the pupae. On the pupae, you can see the distal part of the developing galeae in the midline of the pupae between the developing wings." I spent some time trying to find something illustrating this observation and finally found this amazing photograph by M. Albrecht (from Danner et al., “Die Schwarmer der westlichen Palearktis,” Herbipoliana, Band 4/2, 1998, Plate 46).

That female looks awesome!!
I only saw males and despite lilacs in full bloom I wasn’t able to spot a female. I’m still missing a female of this species leaving in Canada for over 3 decades. I suppose I did not make enough effort.

One of the more difficult hairstreaks to find is the early hairstreak (Erora laeta), rarely found and only in May in this area (Central Ontario). I was fortunate again this year to find a female, here are a couple of pics. Also an aberrant silvery blue (Glaucopsyche lygdamus), note

the absence of the usual spots on the ventral side. Its a female.

In the previous post, the elfins in order are hoary, brown, and bog. The two that follow here are eastern pine and henry's.

A great year for elfins

by mothman55 » Sat May 25, 2024 6:28 pm

Early this May is the time for elfins in Central Ontario. But this year was a great year for these little brown critters. There are five species in this area, and four of the five were as numerous as I have ever seen. The more rare one in the group, the bog elfin (Callophrys lanoraieensis) was also seen in multiple bogs this year, and I was fortunate to see my first ones. The other four species, brown (C. augustinus), hoary (C. polios), henry's (C. henrici), and eastern pine (C. niphon) were found in mass all over central Ontario. In my favourite elfin spot, I saw well over 100 elfins in a 3 hour period. Here

I had to look at the polyxenes I raised a few years ago from Ohio stock. Your butterfly has more orange, my specimens have smaller orange eyespots and no orange on the border.

Unique papilio polyxenes

by mothman55 » Sat May 25, 2024 6:17 pm

Yesterday while watching the lilacs for female Papilio canadensis north of Toronto, I got this interesting female polyxenes. It was the only one of this species I saw in amongst numerous P. canadensis, and in fact I see very few polyxenes in this area (Coe Hill, Ontario). Note the orange spots on the dorsal hindwings, certainly not typical, at least not around

I was also a couple hours north east of Toronto the past 3 days. Canadensis males all over some of the backroads, in the hundreds. But this year the early lilacs are in full bloom the same time as canadensis major emergences. The past few years the early lilac was dead by the time the majority of canadensis came out. So with the lilacs in full bloom and canadensis out in droves, it was a good chance to see females (they don't puddle like the males). There were some especially heavily barred females like the one in this pic from yesterday.

So quick review on tigers.
Toronto And Mississauga: they are flying here around first two weeks of June, one generation only. They are larger than Canadensis and somehow looks like hybrid between glaucus and canadensis.
West of Toronto ( Hamilton, Cambridge and south west of it) I never recall to see tigers there in the spring but I maybe missed them. They are flying starting in end of July, August. I assume these are true P.glaucus as they certainly look like.
North/ east of Toronto ( about 100km ) we can easly find true canadensis around last two weeks of May, begin of June. They are much smaller.
I also found once at Georgian bay Tiger in mid July which I thought was canadensis but it was too late in the season and it is also larger specimen.
It is complex group and to exactly specify fly times and which actually species flies when and where one has to spend more time like Chuck is trying to do now in his region.
