The number of segments in an antenna varies amongst insects, with higher flies having 3-6 segments, [21] while adult cockroaches can have over 140. [22] The general shape of the antennae is also quite variable, but the first segment (the one attached to the head) is always called the scape, and the second segment is called the pedicel.
The second antennae are plesiomorphically biramous, but many species later evolved uniramous pairs. [2] The second antennae may be significantly reduced (e.g. remipedes) or apparently absent (e.g. barnacles). The subdivisions of crustacean antennae have many names, including flagellomeres (a shared term with insects), annuli, articles, and ...
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns (whose larvae are often referred to as roundheaded borers), are a large family of beetles, with over 35,000 species described. [2] Most species are characterized by antennae as long as or longer than the beetle's body.
Some moths have knobbed antennae akin to those of butterflies, such as the family Castniidae. [18] Antennae are the primary organs of olfaction (smell) in Lepidoptera. The antenna surface is covered with large numbers of olfactory scales, hairs, or pits; as many as 1,370,000 are found on the antennae of a monarch. Antennae are extremely ...
The physical variation of antennae is important for the identification of many beetle groups. The Curculionidae have elbowed or geniculate antennae. Feather like flabellate antennae are a restricted form found in the Rhipiceridae and a few other families. The Silphidae have a capitate antennae with a spherical head at the tip.

The development of the halteres varies according to the systematic group: in the Tipulidae are they are thin but long and clearly visible, but are usually hidden by the wings in most other groups. In Calyptratae which includes the most advanced Diptera, the halteres are protected by calyptrae (small membranes above the halteres).
