Observations by Gary Fewless for Green Bay WI (Lat.N 44.51° Long. W 88.02° ), except as noted. For flowers lacking conspicuous petals or sepals I define "anthesis" as release of pollen by mature anthers.

June 2002

Observations by Gary Fewless, except as noted

Date Observation (Click on links for photos)

Clasping Dogbane (Apocynum sibiricum) and Enchanter's Nightshade (Circaea lutetiana) first day of flower. Also Tall Anemone (Anemone virginiana) in flower, but not first day, UWGB (Gary Fewless).

Very hot and humid, high temperature of 92F, the hottest day of the year to date. Many plants "wilting" in the heat, and animals too, as in this photo by Matt Welter of baby Robins on Friday (Gary Fewless).

Many people have commented on how rainy June was this year. It did rain many times, at least a trace of rain on 18 of 30 days. However the amount of water received was only about 1/16 inch above average for June.

Note a couple of late entries for butterflies on June 23 and 28.

June29 Purple Loosestrife (Lythrum salicaria), Canada Thistle (Cirsium arvense), Swamp Thistle (Cirsium palustre), Yellow Pond Lily (Nuphar variegata), Wild Parsnip (Pastinaca sativa), Black-eyed Susan (Rudbeckia hirta) and Hedge Bindweed (Convolvulus sepium) all in first flower or very close. White Water Crowfoot (Ranunculus longirostris) apparently in flower for at least several days. Deer Flies abundant and obnoxious. Marinette County, Town of Peshtigo (Gary Fewless).

Lesser Goat's-beard (Tragopogon pratensis) in flower, Allouez (Gary Fewless). Note that our other (and much more common) species of Goat's-beard, Tragopogon dubius, began to flower 06/02.

Orange Day Lily (Hemerocallis fulva) and Mayweed (Anthemis cotula) first flower, UWGB (Gary Fewless). The fact that "Mayweed" doesn't flower until late June is not as illogical as it may seem. This species is found in all 50 states, north from Newfoundland to Alaska and south beyond the borders of the U.S.A., in addition to it's native range in Europe, so it probably does flower in May in some parts of its range. It is closely related to Chamomile, and is roughly similar in appearance, but it has an unpleasant odor quite unlike Chamomile. Daylilies also in flower in Shawano County (Joel Whitehouse).

The water level in Green Bay (and Lake Michigan) is up about 10 inches compared to last year at this time. On average the lake level reaches an annual high point in July and then falls until January or February. Major deviation from average weather can alter this cycle to some extent.

The first Pearl Crescent butterfly (Phyciodes tharos) that I've seen this year, City GB (Gary Fewless). If someone has seen this one long since, please let me know.

Aphrodite fritillary (Speyeria aphrodite), T. of Cooperstown, Manitowoc
County (Joel Trick).

Both Yellow Pond Lily (Nuphar variegata) and White Water-lily (Nymphaea odorata) flowering in Oconto County (Joel Trick).

Haze from fires in southwestern U.S. arrive finally here, making sunsets more colorful, sunlight more golden and shadows fainter and more purple, West De Pere (Matt Welter).

Ovenbird chick fledged and food begging. Butterfly milkweed (Asclepias tuberosa) and Grass Pink (Calopogon tuberosus) in Flower. Bog Copper butterflies flying about in "bog", Black River State Forest, Jackson County, WI (Andy Paulios).


I have made late entries for several flowering dates as far back as 06/21, after bringing together all my "pocket notes" and even a few photos that captured dates not otherwise recorded (gf)

Sow Thistle (Sonchus uliginosa) in flower, UWGB. Common St. John's-wort (Hypericum perforatum) also first flower, just a few plants along Highway I43 near UWGB. Many other plants have partially open buds and will flower in the next day or two (Gary Fewless).

A few flowers of Chickory (Cichorium intybus) in flower in Ashwaubenon (Matt Welter), Bellevue and City of Green Bay (Gary Fewless). The first flowering plants are immediately adjacent to curbs. These sites warm up a little quicker in the spring and many weedy species flower a few days earlier near curbs or along the edges of sidewalks, etc.

First flowers of Little-leafed Linden (Tilia cordata), West Depere and downtown Green Bay (Matt Welter).

White Trillium (Trillium grandiflorum) still in peak flower in northern Florence and Forest Counties; none of the flowers had started to turn pink. There were even a few of the northern Spring Beauties (Claytonia caroliniana) still in flower.
