Insects have two main types of feelers, antennae and palps. Antennae are long, thin appendages that protrude from the head of an insect and are used for sensing their environment. Palps are short, finger-like structures located near the mouth of an insect and are used for tasting and manipulating food. Both antennae and palps are important sensory organs for insects, allowing them to detect changes in their environment and to interact with their food sources.
