Some claim insects evolved from prehistoric crustaceans, and they have secondary antennae like crustaceans, but not primary antennae. 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 ...
Of all the insect orders, Orthoptera displays the greatest variety of features found in the heads of insects, including the sutures and sclerites. [6] Here, the vertex , or the apex (dorsal region), is situated between the compound eyes of insects with hypognathous and opisthognathous heads.

Legend: a, antennae; c, compound eye; lb, labium; lr, labrum; md, mandibles; mx, maxillae; hp hypopharynx.
The forelegs are reduced in the Nymphalidae Diagram of an insect leg. The thorax, which develops from segments 2, 3, and 4 of the larva, consists of three invisibly divided segments, namely prothorax, metathorax, and mesothorax. [11] The organs of insect locomotion – the legs and wings – are borne on the thorax.

[1] Thus, it is the most important sensation for insects. [1]
