What distinctive color is found on the fifth abdominal segment of the Vestal Cuckoo Bumblebee?
Answer
White
The hair located on the fifth abdominal segment, also known as the tergite, is predominantly white. This creates a clear whitetail tip at the end of the bee's abdomen. This feature, in addition to the collar color and the yellow markings on the thorax junction, serves as a primary visual diagnostic mark for identification in the field.
