Antennae are the primary olfactory sensors of insects [7] and are accordingly well-equipped with a wide variety of sensilla (singular: sensillum). Paired, mobile, and segmented, they are located between the eyes on the forehead.

Apr 18, 2020 · The Insect Head: Guide To The Antennae, Eyes & Mouthparts. The insect head is sometimes referred to as the head-capsule and is the insect’s feeding and sensory centre. It supports the eyes, antennae and and jaws of the insect

Sep 17, 2024 · Insects have both compound eyes, made up of multiple ommatidia for sensing movement and providing a wide field of view, and simple eyes (ocelli), which aid in determining light intensity. These modifications of insect antennae help insects move, communicate, and thrive in a variety of habitats.

Oct 1, 2019 · Insect antennae are segmented, and usually located above or between the eyes. How Are They Used? Antennae serve different sensory functions for different insects. In general, the antennae might be used to detect odors and tastes, wind speed and direction, heat and moisture, and even touch.

Sep 25, 2024 · Insects possess specialized sensory appendages known as antennae, which play a vital role in their interaction with the environment. These structures are primarily responsible for detecting chemical signals, vibrations, and other stimuli, …

Mar 4, 2025 · Antennae (singular: antenna) are sensory appendages found in the head region of insects and other arthropods. They are primarily involved in detecting chemical cues (smell and taste), tactile sensations, temperature, humidity, and even sound vibrations.

Insects with large and elaborate antennae usually have a better sense of smell. Some insects can detect odors from over a mile away! Insects have a pair of large compound eyes with many tiny lenses. Some insects’ eyes wrap around their entire heads, allowing for 360-degree vision.

Insects detect these odors with receptors mostly located on the antennae, and the diverse shapes and sizes of these antennae (and sensilla) are both astonishing and puzzling: what selective pressures are responsible for these different solutions …

The antennae of insects are modified in many ways. Some of these modifications just provide greater surface area for sensory receptors, while others are unique adaptations that bestow special sensory capabilities, such as detecting sound vibrations, wind speed, or humidity.
