Not all arthropods use spiracles to obtain oxygen, but many do. Spiracles are openings on the exoskeleton that lead to a network of tracheae, allowing gas exchange. Aquatic arthropods, such as many crustaceans, typically use gills instead of spiracles for respiration. Therefore, while spiracles are common in terrestrial arthropods, they are not universal among all arthropods.
Butterflies have nine pairs of spiracles. These are pores open to the air and tracheae which carry air through the body of an insect. Spiracles are located on the abdomen and thorax.
