scopula

American Heritage® Dictionary of the English Language, Fourth Edition

1. n. A dense brushlike tuft of hairs, as on the feet of certain insects.

Century Dictionary and Cyclopedia

1. n. In entomology:
2. n. A small scopa or brush-like organ. Specifically— A series of bristles or bristly hairs on the tarsi (usually the hind tarsi) of certain hymenopterous insects. These are well marked on the first joint of the hind tarsi of honey-bees, forming a part of the corbiculum. (See cut under corbiculum.) The drones of honey-bees and the parasitic bees have scopulæ, not for pollen-bearing, but for cleansing the body. These are called brushlets, and a group of solitary bees is named Scopulipedes from this character. A bee's leg so furnished is said to be scopulate.
3. n. [capitalized] A genus of pyralid moths.
4. n. In sponges, a fork- or broom-shaped spicule, consisting of a long axial shaft to the distal end of which generally four slender rays are attached.
