||Observation (Click on links for photos)
||New species in flower in Brown County: Cichorium
intybus (chickory), Calystegia sepium (=Convolvulus
sepium, hedge bindweed), Melilotus alba (white
sweet-clover), Cicuta maculata (common water-hemlock),
Sonchus arvensis (sow thistle).
Several additional plants began to flower in the last few days:
Verbascum thapsus (mullein), Catalpa speciosa (northern catalpa,
cultivated only), Sambucus canadensis (black elderberry), Agropyron
repens (quack grass).
This appears to be a banner year for Penstemon digitalis in the
UWGB Cofrin Arboretum prairie. They are numerous and robust and
in peak flower now.
Fireflies or lightning bugs (Lampyridae) common now; I didn't
record the first date I saw them, but I think it was about one week
ago. Town of Cooperstown, Manitowoc County (Joel Trick).
The above note is very interesting. Lightning bugs appear in my
neighborhood (Allouez, Brown County) in many years in late May or
early June. It has been my observation that they are strongly inhibited
by rainy and cool weather, and May and most of June would certainly
qualify in that area this year. We saw lightning bugs on May 20
in far southwestern Wisconsin (Grant county), but still have not
seen them in our neighborhood (Gary Fewless).
Phleum pratense (timothy) and Geum aleppicum
(yellow avens) in flower (anthesis) UWGB.
Cool weather continues in northeastern Wisconsin with highs of
71 F and lows of 49 in Green Bay for each of the last two days.
Rhinelander's highs were in the 60's and the low was 39 F on the
Cirsium arvense (Canada thistle) in flower, City
|| A couple of species in flower that I neglected
to enter here previously: Coreopsis lanceolata (sand coreopsis),
Viburnum rafinesquianum (arrow-wood), Thalictrum
dasycarpum (tall meadow-rue).
||Severe thunderstorms and a few "funnel
clouds" reported at various places in Wisconsin. The tornado
sirens went off several times in the evening, but most of the severe
weather passed either south or north of my location in Allouez.
Heliopsis helianthoides (false sunflower) and Melilotus
officinalis (yellow sweet-clover) in flower, UWGB.
Tragopogon pratensis (lesser goat's-beard) in flower,
||Cornus racemosa (gray dogwood)
and Hypericum perforatum (St. John's-wort) in flower,
Rubus allegheniensis (blackberry) in flower, Florence
A cold morning in the north--Rhinelander reported a low temperature
of 36F (Green Bay's low was 47).
The rainy weather of May and the first half of June has kept many
rivers high and potentially dangerous for boaters and others
spending time on and near the rivers. There have been several fatalities
already this year in Wisconsin streams.
Mosquitos are more abundant than they have been in the the
last couple of years, but not particularly bad (in my experience)
in northeastern Wisconsin (others have reported heavy mosquito populations,
but over the long run, this year doesn't seem extreme to me).
After a couple of days in Florence County, I have seen very little
damage to the forest from the forest tent caterpillars (we tend
to note only when they are abundant and omit comment when they are
not). As a consequence, the "friendly flies" that parasitize
the forest tent caterpillars are also not abundant. Both species
may yet make a showing if conditions are favorable.
||The common old field weeds Hieracium
aurantiacum (orange hawkweed) and Chrysanthemum leucanthemum
(ox-eye daisy) are conspicuously in flower on disturbed, sunny
sites in northeastern Wisconsin.
||1.27 inches of rain in Green Bay.
Medicago sativa (alfalfa) and Bromus inermis
(brome grass) in flower, Allouez.
Baptisia alba (white wild indigo) and Rosa multiflora
(multiflora rose) in flower UWGB.
First day of flower for Convolvulus arvensis (field bindweed),
Allouez, and Carduus nutans (nodding thistle).
Geum triflorum (prairie smoke--planted individuals)
is in fruit.
While I was out of town for a few days the following species began
to flower (since June 9) on UWGB: Crataegus crusgalli (cockspur
hawthorn), Lithospermum officinale (common gromwell),
Robinia pseudoacacia (black locust), Galium mollugo
I have seen very few Tiger Swallowtail butterflies in northeastern
Wisconsin this year.
||Vitis riparia (wild grape)
and Tradescantia ohioensis (spiderwort--just a few flowers)
in flower, UWGB.
||Plants beginning to flower: Hieracium
florentinum (yellow hawkweed), Acorus americanus
(sweet flag) Tradescantia ohioensis (spiderwort--just
a couple of open flowers today), Smilacina racemosa (spikenard),
Solanum dulcamara (bittersweet nightshade), Iris
virginica (blue flag), UWGB.
||Dactylis glomerata (orchard grass)
in flower (anthesis), UWGB. It started 2 days ago in Allouez and is
now in peak flower there.
Iris pseudacorus (yellow iris), Zizia aurea
(golden alexanders), Hieracium aurantiacum (orange
hawkweed), Lotus corniculatus (birdfoot trefoil),
Sanicula gregaria (clustered black snakeroot), Heuchera
richardsonii (prairie alumroot), Osmorhiza claytonii
(sweet cicely), Chrysanthemum leucanthemum (ox-eye
daisy), Achillea millefolium (yarrow) first day
in flower, UWGB.
Geranium maculatum (wild geranium) and Hydrophyllum
virginianum (Virginia waterleaf) are among the most conspicuous
flowering plants in Mahon woods, UWGB.
Populus deltoides (cottonwood) is dispersing its
seeds now. This is the "cotton" from which it derives
its common name.
Any guesses on the 3 flowers shown above? One is easy, one medium
difficulty and one difficult, not necessarily in the order shown.
Rubus occidentalis (black raspberry), Heracleum
lanatum (cow parsnip), Vicia cracca (cow vetch)
in flower, UWGB.
Mosquitos just now getting obnoxious on UWGB, and only in
the wetter woods.
Dactylis glomerata (orchard grass) in flower (anthesis),
Acer saccharinum (silver maple) dropping mature fruit,
Allouez (some immature fruits were dropped earlier).
Lonicera dioica (red honeysuckle) in flower and Osmunda
cinnamomea (cinnamon fern) dispersing spores, Ashwaubenon.
||Cornus alternifolia (alternate-leaved
dogwood) and Anemone canadensis (Canada anemone)
in flower, UWGB.
Potentilla simplex (common cinquefoil) in flower,
Potentilla argentea (silvery cinquefoil) in flower,
DePere (on barren sites in full sun this species may flower at least
a week earlier than in lawns, grassy roadsides, etc.).
This is the first day that I've seen Oxalis stricta (wood
sorrel) in flower on UWGB's Cofrin Arboretum (some flowered
earlier near buildings). There is widespread flooding of local streams
following the recent rains (1.6 inches in the last two days on land
that was already thoroughly saturated).
