Which body part of an insect is located between the head and the abdomen and has legs attached?

The body part of an insect that is located between the head and the abdomen, and to which the legs are attached, is the thorax. This section of an insect's body is specifically designed for movement and locomotion, accommodating the three pairs of legs that insects typically possess. Additionally, in many cases, the thorax can also support wings, which are crucial for the flight capabilities of certain insect species.

The head is the front part of an insect, primarily responsible for sensory perception and feeding. The abdomen is located at the rear of the insect's body, containing vital organs and being involved in reproduction and digestion. The cephalothorax is a term used primarily in arachnids (like spiders and scorpions) that refers to a fused head and thorax, which is not applicable to the structure of insects. Therefore, the thorax stands out as the correct answer due to its definitive placement and role in an insect's anatomy.
