How does the carder bee's method of material transport contrast with that of bumblebees?

Answer

Carder bees use a scopa on the abdomen, whereas bumblebees primarily rely on pollen baskets (corbiculae) on their hind legs.

The carder bee utilizes the scopa on her abdomen for bulk transport of fibers, which contrasts sharply with bumblebees that primarily rely on corbiculae located on their hind legs for carrying materials like pollen.
