Meadowhawks have been nonexistent here this fall. The ponds I usually see them
around are almost dry so maybe that has something to do with it.

Subject: [tn-dragonflies] late season dragonflies
As we have seen with butterflies this season, some odonates will be around
late
into the fall.
Cool temps, in the upper 20s and low 30s, a frost or a light freeze, will not
necessarily kill late-season adapted odes. "A hard freeze", in the low 20s and
teens, we have not had yet in the state anywhere except maybe the
mountain-tops. That's what it would take to kill these insects and put a
final end to the season.
Even after several "frosts" Marlene reported that on 11/10 in Carter Co.she
still had Shadow Darner, Autumn Meadowhawks, and Great Spreadwings.
On 11/9 in Davidson County at Hidden Lake SP I had 2 Com. Green Darners
feeding
over the meadow, and 4 American Rubyspots on the Harpeth River. Over the
meadow
I could see small insects in the air. So unlike our butterflies which may run
out of food source before they are actually killed of by the cold, the
dragonflies can usually find some other smaller insects to feed on. Any mild
winter day there will be a hatch of small insects flying about, this is one way
our rare, wintering western hummingbirds can survive the winter the here.
The adult dragonflies are not that hardy.
