||Observation (Click on links for photos)
||Immature Little Brown
Bats (Myotis lucifugus) hanging out on on shaded
sides of building during the day. I now expect to hear from people
who have bats in their homes as immature bats are curious about new
openings and spaces such as dryer vents, bathroom ceiling fan vents
and other odd "entrances" to peoples homes. Best bet is
to leave your a door or window open and let them find their way back
out. Broadway District if Green Bay (Matt Welter).
||A few leaves of Virginia
Creeper (Parthenocissus inserta) turning red, Oneida County
||The first sign of fall leaf
color change in northeastern Wisconsin (at least for this year) is
the yellowing of the leaves of Spreading Dogbane (Apocynum
androsaemifolium), Florence County (Gary Fewless).
(Solidago nemoralis) in flower, UWGB (Gary Fewless).
I'm seeing a few red leaves on Virginia Creeper
(Parthenocissus inserta) and Gray Dogwood (Cornus
racemosa) on UWGB's Cofrin Arboretum, but most plants are still
(Asclepias verticillata) in flower, Brown County, Town of Suamico
(Gary Fewless). It appears to have been in flower for several days.
Great Blue Lobelia
(Lobelia siphilitica) well into flower, Baird Creek area
(Gary Fewless). It has probably been flowering for at least 3-4
We are getting to the point where there are not
many species of plants that haven't flowered yet. The conspicuous
species not yet in flower include several prominent Asters, Goldenrods
The trees in the Green Bay area are still in full
summer green. We may begin to see color change in the earliest species
within the next couple of weeks, especially in stressed or less
robust individuals. Staghorn Sumac (Rhus typhina)
and the vine Virginia Creeper (Parthenocissus inserta)
are among the first woody species to begin leaf color changes in
||Purple False Foxglove
(Gerardia purpurea) well into flower, Door County. I estimate
that it has been in flower for at least 4-5 days and maybe longer
(Aster macrophyllus) is in flower in Brown County (Gary Fewless).
It has probably been flowering for at least several days and maybe
more. In forests this species may be present in very large numbers
as sterile (non-flowering) plants. If an opening in the canopy occurs,
they may flower in large numbers in the next growing season.
(Silphium terebinthinaceum) in flower, UWGB (Gary Fewless).
This is a planted individual in the prairie on the Cofrin Arboretum.
In 9 years of observations of this same individual plant this is
by far the latest it has flowered. Previous observations ranged
from 07/21 to 07/29, with an average of 07/26. Prairie Dock makes
a very good phenology subject because individual plants are large
and easy to locate, the flowers are large and conspicuous, and individuals
live for a very long time.
Common Nighthawks migrating,
Sauk County (Andy Paulios).
(Eupatorium rugosum) in flower, Bairds Creek area (Gary Fewless).
are beginning to aggregate in the East River adjacent to the marshes
at night (Gary Fewless). A sign of the imminent change of seasons.
||The first open flowers of
Canada Goldenrod (Solidago canadensis) at UWGB (Gary
Fewless). This is a good time of year to see clearly the clonal nature
of the Golednrods. As you look across a field you can see the earliest
flowering plants (mostly Solidago gigantea at this stage in
the Green Bay area) as distinct "islands" in the field.
Each flowering group (clone) may actually represent a single individual
plant, the stems all connected belowground.
glabra) in flower (apparently for at least several days), Florence
County (Gary Fewless).
(Aster Umbellatus) in flower, Florence County (Gary Fewless).
(Anaphalis margaritacea), Flat-leaved Bladderwort
(Utricularia intermedia) and the very first flowering plants
of Canada Goldenrod (Solidago canadensis) and Northern
Bog Goldenrod (Solidago uliginosa) in flower, Florence
County (Gary Fewless).
Yellow Warblers migrating
south,Wisconsin Point, Superior, WI (Andy Paulios).
(Ambrosia artemisiifolia) and Giant Ragweed (Ambrosia
trifida) both in flower (anthesis) Baird Creek area, and Allouez
(Gary Fewless). Common Ragweed is by far the most serious problem
for August and early September hayfever. At this time of year many
people begin to complain of "summer colds" and many will
even remark that they seem to get a summer cold every year at this
time. It may very well be that they are suffering from Ragweed hayfever.
One plant of Giant Sunflower (Helianthus
giganteus) with 3 open flowers seen, Baird Creek area (Gary
Fresh, recently emerged Viceroy and Black
Swallowtail butterflies, Baird Creek (Gary Fewless).
(Clematis virginiana), Allouez (Gary Fewelss).
(Echinocystis lobata) first flower, Allouez, along the East
River (Gary Fewless).
