What is a defining visual characteristic of the wings of the Vestal Cuckoo Bumblebee?

Answer

They are dull and smoky in appearance.

The wings of the Vestal Cuckoo Bumblebee display a dull, smoky quality rather than being fully transparent or brightly colored. This characteristic contributes to the generally darker and less vibrant visual profile of the species. When combined with the sparse fur and the visible, shiny black exoskeleton, this wing appearance is a consistent trait that helps differentiate these parasitic bees from their more colorful social counterparts.
