On August 30, Professor David Angelini made a solo survey of Allen Island looking bumblebees. He found 59 individuals of 5 species, all north of the ponds in the middle of the island. The species of our greatest interest, Bombus borealis made up about 20% of the bees, down from being the overwhelming majority of foraging bees on Allen in July. However, this number is still high compared to most areas of the mainland.
