scopa

The term "scopa" in zoology refers to a specialized structure found on insects, primarily bees, that functions like a brush for collecting pollen. This adaptation is crucial for pollination and varies among different bee species.12

In some primitive bees, like those in the families Colletidae and Halictidae, the scopa is a dense arrangement of hairs on the hind legs and abdomen. As bees evolved, the scopa became more specialized. In social bees, it's typically found on the outer sides of the hind legs, forming a "pollen basket" or corbicula. For leaf-cutting bees (Megachilidae), the scopa is located on the underside of the abdomen. In certain species, the scopa may be absent, with pollen carried in the crop. The term "scopa" itself originates from the Latin word for "broom".21
