was recorded 27 times in the past 30 days across the Milwaukee region, with the most recent observations on 2026-09-17 in Wisconsin. This introduced species is widely distributed in the area as it enters its seed dispersal phase in early fall, when its fruit becomes edible to birds that spread it further. Abnormally dry conditions affecting 66.19% of Milwaukee County may reduce predation or disease pressure on this invasive shrub.

Thirty-nine bumble bee records, most from a handful of sites

August 17, 2026

Thirty-nine research-grade sightings of the were logged across the Kettle Moraines area in the past 30 days. That is the same figure from both available sources — iNaturalist's species roster and the individual observation records — pulled over the same 30-day window and the same 25 km radius. The dates fall in the late-summer stretch when colonies are provisioning new queens before the season ends. Bombus affinis was once common from the upper Midwest into the Northeast, but its range has collapsed by an estimated 90 percent since the late 1990s, and it was listed as federally endangered in 2017, the first bumble bee species in the continental United States to receive that status. A few strongholds remain, and this stretch of southeastern Wisconsin, with its mix of oak savanna, prairie remnant, and undisturbed ground for nesting and overwintering queens, is one of them. Queens of this species need to keep finding nectar and pollen right up until they enter diapause for the winter, so a bee spotted now is doing some of the most consequential foraging of its whole life cycle. She is building fat reserves that have to carry her through months underground, alone, before she can found a colony next spring. But the count itself should not be read as a trend. Eight of the 39 records come from Greenfield Park in West Allis and several more from a single address in Waukesha, so the number tracks where people are out looking at least as much as where bees are. What these records establish is presence and activity across the landscape right now — not that the population is stable, growing, or larger than last year. Separately, and worth noting without overstating its connection to the bees: the ESSENTIAL INDUSTRIES INC
