Phenology

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.

Jun25	Staghorn Sumac (Rhus typhina), Canada Thistle (Cirsium arvense), Orange Day Lily (Hemerocallis fulva) in flower, UWGB (Gary Fewless).
Jun24	Milkweed (Asclepias syriaca), Common St. John's-wort (Hypericum perforatum) in flower, UWGB, (Gary Fewless).
Jun23	Thousands of juvenile American Toads emerging from tadpoles, UWGB prairie pond (Steve Price).
Jun22	Blue Vervain (Verbena hastata) in flower, UWGB (Gary Fewless)
Jun20	Black Elderberry (Sambucus canadensis) in flower, UWGB (Gary Fewless).
Jun19	Both Narrow-leaved and Broad-leaved Cattails (Typha angustifolia and Typha latifolia) in flower, UWGB (Gary Fewless).
Jun17	Bluebird feeding flying young, Manitowoc Co, Cooperstown area (Joel Trick). Lance-leaf Tickseed (Coreopsis lanceolata), Manitowoc County (Joel Trick)
Jun16	Four-toed salamander eggs hatching, Door Co (Steve Price).
Jun15	Gray Dogwood (Cornus racemosa) and King Solomon's-seal (Polygonatum biflorum) in flower, UWGB (Gary Fewless). A front moving through the area cooled temperatures last night and steady rain is falling today.
Jun14	Early Wild Rose (Rosa blanda), our commonest wild rose, in flower UWGB (Gary Fewless). Hot, humid weather continues--high temp 88.
Jun13	Reed Canary Grass (Phalaris arundinacea) in flower UWGB (Gary Fewless). Hot, humid weather arrives with high temp of 88 in Green Bay.
Jun11	Brome Grass (Bromus inermis) has begun flowering, but so far only along street edges; Ox-eye Daisy (Chrysanthemum leucanthemum) in flower, UWGB (Gary Fewless).
Jun10	These conspicuous species have begun flowering in the City of Green Bay since the 6th: Annual Fleabane (Erigeron annuus), Yellow Sweet Clover (Melilotus officinalis), Blue flag (Iris virginica), (Gary Fewless). Painted Turtle laying egss, Manitowoc Co, Cooperstown area (Joel Trick). I saw some large outbreaks of Forest Tent Caterpillars in Vilas and Forest Counties over the last several days. The caterpillars had removed virtually all the leaves in some big stands of Trembling Aspen (Populus tremuloides). Many other trees were also affected, but none as severely as the Aspen. There were so many caterpillars that they spilled over into all adjacent habitats, even clumped sedges in standing water and there was a steady stream of catepillars floating (swimming in a crude fashion) on the surface of a small creek that I crossed. Many species in the forest utilize the caterpillars as a prey species and typically these outbreaks are of short duration ( a year or two). Flesh Flies (also called "friendly flies" in the press) are one conspicuous species which acts to control caterpillars by parasitizing them. We can expect a large increase in the number of Flesh Flies during the months ahead. (Gary Fewless)
Jun06	Cool weather and rain have slowed the development of new flowers. Today was a big day for pollination in the Red Pines (Pinus resinosa) in Vilas County (Gary Fewless).
Jun01	Black Locust (Robinia pseudo-acacia) in flower, UWGB (Gary Fewless). The cold, rainy weather which arrived today will slow the development of the plants (Gary Fewless).
