7/23/2017 – Saw 5 of these on Cup Plant (silphium sp.) All had very extended abdomens. A friend on Facebook pollinator group suggested it may be Bombus Fraternus. If so, this is good news as I believe they are in a threatened status. Thanx in advance for your expert assistance.

These images do indeed look like a Southern Plains Bumble Bee when compared to this BugGuide image, also taken in North Carolina. According to BugGuide: “Has disappeared from the northern margins of its range, with few or no records from the northernmost states where recorded historically, but still regularly encountered in its core range on the southern Great Plains, and still found in the Southeastern United States.” This species, as you indicated, is listed as endangered on the IUCN Red List. Congratulations on your awesome sighting and thanks so much for sending in your images with the identification.
Thank you for your response. Your staff is amazing.
