early fall

[I Macaulay]

A while back some scientists said that the extra heat  would cause the trees to drop their foliage earlier than normal, Quite the opposite of what one would expect.   Is this what is happening or is it all just lack of water?

I found this but do not know which show it actually was on:   The CBC Radio's "Quirks & Quarks" special, "Overheated," explored the effects of global warming on the seasons, including the potential for early falls.

* we'd have to have a hot wet August to see, which wouldn't be a lot of
fun. Here the Manitoba Maples that were registered as "yellow" in this
morning's post are now brown, and the ground is covered with fallen
leaves, and the little pond is covered with fallen leaflets from the
adjacent Black Locust trees. Across the street there's a clump of small
Sugar Maples with most of their leaves looking very crispy, and a little
Elm tree which grew large leaves this spring has them all wilted &
hanging vertically.

Back in the 1999 and 2001 droughts there was some "releafing" of
Buckthorn when the droughts broke and new leaves grew on shrubs that had
shed all their leaves - I'll have to look up what my methods were then,
and be prepared for the possibility this fall.

On another note, the leaves of our scattered Milkweed out back are now
all tan & crispy, and the Ramps ("Wild Leeks") which usually put up
their flowerstalks in late June or July haven't bloomed in any of our
introduced patches.

And speaking of Milkweed, Not a single Monarch seen this year.

I have not been touring my property at all but do have a milkweed and echinacea garden on the front lawn.

Very few visitors and still very few  mosquitoes.

Senility has been a smooth transition for me.

I did see a single Monarch up near Maniwaki on Saturday.

* we've seen 3 Monarchs so far, most recently a big bright one on
drought-withered Phlox flowers here yesterday. We've never had Monarch
caterpillars on our Milkweed, and now the leaves are all dry & crisp
from the drought, so there was no egg-laying potential to detain the
butterfly.

We've had a few brief sightings of Canada & Giant Swallowtails here, but
they've generally been going past so fast that it's been hard to
identify them.

I have seen 2 more monarchs since my last reply, still no
caterpillars. I keep watering the milkweeds out front and hoping.

There have not been many butterflies, but then I haven't been out and
about that much with this miserable heat. I have a few buttonbush
bushes down by the lakeshore, and I was waiting to see what would come
to those when they were in bloom. I usually get several species.
This year, nada.

The moths have put in a good showing at my lights, picked up several
new species. So far I've seen 6 Barrens moths and managed to
photograph 5 of them. I've also had 2 walkingsticks and and a
pelecinid moth, both of which I haven't seen for a couple of years.

Temperatures are supposed to more reasonable this week, hopefully I
can go for a couple walks in my woods, which I've been missing out on
this summer. Also go out to the neighbour's fields and check out the
milkweeds and joe pye weeds at the edges, see what insects are lurking.

We have seen no monarchs around our place but giant swallowtails have been around for several weeks, including three of them playing the other day - between the phlox and the cone flowers.

We've had a few giant swallowtails pretty much throughout the summer.
They love the wet sand at the edge of the beach.

I've been checking my prickly as bushes but have not yet found caterpillars.
