Odd Bee Identified

by Carl Strang

The Beespotter folks got back to me in recent days and confirmed that the odd bumblebee I reported earlier was indeed a male Bombus bimaculatus.

This confirms in my mind that bimaculatus is an early-season species in northeast Illinois, as males appear toward the end of a species’ season. In support of that notion, in recent days I have seen increasing numbers of Bombus impatiens, the common late-season short-tongued species, as they replace the declining bimaculatus.
