First bumblebee I’ve seen this year! No clue what specific kind it is though. The very last photo has it taking off/flying. It’s on lance-leaved coreopsis!
Lance-leaved coreopsis observation: https://www.inaturalist.org/observations/209284835
in the native plant garden plot at the DEP site.
ID confirmation appreciated
Or is it one of those “mottled” hybrids?
