The first tigers are flying in central Ontario (Haliburton, Trent Lakes) this week. The heat wave this past few days has brought out the early birds. We are still probably a week or two away from the masses, which is typically early June. These are P. canadensis in this area.

Low. I have an almost 2 year old so free time is hard to come by. Let’s plan for 2025 then. Border might be open by then and we can hop back and forth.

Be interesting to know what flies in Niagara Falls. One would think we could narrow down ranges in an area populated for 300 years and now with four million humans, and motorways to everywhere. Chuck

4 million? About 88,000 people live in Niagara Falls, ON.
I think 1 in 88,001 people study Lepidoptera...

I still haven’t seen any P.glaucus around Toronto area this spring.

I have seen tigers (assume P. glaucus) in Pickering, just east of Toronto, and a friend has seen them in Mississauga (just west of Toronto), so you should see the odd one now in Toronto. Typically they would be glaucus in Toronto, and canadensis further north into central Ontario.

I have collected and or reared the Eastern Tiger Swallowtail from Northeast Ohio. They over winter as early instar larva and are on the wing by early June and the second brood in early August. I have a few specimens from late September and early October.
In the mountains of Southwest Virginia they first appeared in early April and could be found on a warm autumn day in late October. Dark females appeared in late May, became more numourus in July and August. Dark females came in numorous and marked rather Bazaar.
Fields of Clover, Milkweed and Joepeye Weed could produce some phenomenal collecting.
Several of my drawers of Pterourus glaucus appeared in another thread. I am sure others will find them and repost them.

Interesting, as our glaucus in Finger Lakes overwinter as pupae.

You sure about that? I have never heard of glaucus larvae hibernating.

Where is the glaucus/ canadensis split on the Lake Ontario north shore?
You know how many times I’ve been in Mississauga, darling, picton, Kingston and ignored the tigers? Doh. Heck, I’ve been on Main Duck Is, false duck, and Galloo. And ignore the yellow ones.

I concur with eurytides remark.
I have never read or heard of P. glaucus or any other swallowtail species over-wintering in any larval stage here in Neartic zone.
As we all know the chrysalids of butterflies are surprisingly durable throughout our Northern winters. Of course, somewhat sheltered situations afford even more protection for them.
Eggs of course makes sense to me as well for overwintering.
I have both read and heard that certain moth larvae are able to make it through our winters by either making a flimsy cocoon in leaf litter and such or through a thick coating of hair such as wooly bear (larvae) have.
I have collected at least 3 early (spring) form P. glaucus as early as the first week of May; here in Illinois. They are noticeably smaller than any that I pick up in late June.
But, honestly most springtimes I rarely see any P. glaucus at all ! I believe our weather is (most often) too unsettled in May to allow any eclosed adults to survive more than a couple two or three days.
Our spring time here (April/May) is overall a pretty tough season for most of our butterflies; except of course for the hibernating nymphalid species. Seems like anything else you may catch a glimpse of probably has a very very short existence as an adult.

In North America and Eurasia there are many groups of butterflies and moths that overwinter as larvae, but as far as I'm aware all Papilionidae in this region overwinter as pupae, except Parnassius which overwinter as ova.

As a qualification to my last remark, there are a few Parnassius that have a 2-year life cycle, so the second winter would be spent as a larva or pupa. But all Papilio certainly overwinter as pupae.
