What is the function of antennae in insects and what are two common antennal types?

Antennae are the primary sensory tools of insects, acting as their main chemosensory and tactile organs. They host numerous sensory hairs and receptors that detect odors (smell), contact, humidity, and temperature, helping insects find food, locate mates, and sense their environment. Two common antennal shapes are filiform, which are long and threadlike, and moniliform, which look like a string of beads. The specific shape affects how much surface area and sensilla an antenna has, influencing sensory capacity, but both types serve the same general function of sampling chemical and tactile information from the surroundings. Hearing and balance aren’t the main roles of antennae in most insects, though some specialized species may have adaptations related to those senses.
