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.

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).

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).


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).
