Phenology

Second Week of May

Gray catbirds and wood thrushes return and sing. Orchardists look for a strong bloom on Zestar, Honeycrisp, Haralson, and other apple tree varieties, and also on pear trees. Expect the first few mosquito bites and to see the first eastern tiger swallowtail butterflies on the wing. The common morel - our state mushroom - makes fabulous eating but should not be eaten raw. Many mushroom hunters look for morels after a rainfall during lilac blooming time. Lake surface temperatures are usually in the 50s for the Minnesota Fishing Opener, which is by tradition the biggest outdoor event of the year and heralds the start of summer.

May 6, 2017: The first wildflower, the Canada violet, began blooming on this day, the same date as a year ago. The first migrating white-throated sparrows returned in numbers.
