Insect antennae come in a variety of forms, and are an important characteristic to examine when trying to identify an insect. Some insects, like Proturans, lack antennae. If the antennae are not clearly visible, use a hand lens to get a better look. Do they appear threadlike or are they club-shaped? Do the antennae have an elbow or bend? Are they feathery or bristled?
