This illustrated guide is designed to help students recognize and learn the different types of antennae found on arthropods. The single Web page, which can be easily printed for use at field sites or in the lab, shows
- plumose (featherlike)
- pectinate (comblike)
- serrate (sawlike)
- moniliform (beadlike)
- filiform (threadlike)
- aristrate (with bristles)
- elbowed (with a bend)
- clubbed (the segments towards the end are larger)

Supplement a study of biodiversity with an activity drawn from this guide to types of antennae.
- Discuss how arthropods use their antennae to sense the world.
- Send students to this online guide, or print copies of it for them to reference.
- Have students select three antennae types, find an arthropod that has each one, and research how the antennae differences change the arthropod's ability to sense the world.
