Examples: Carrion beetles of order Coleoptera. However, this segment would have evolved into a reduced and inconspicuous piece, now being unappreciable. Because the segments are of uniform widths, there is no taper to filiform antennae. So, insects taste, smell, touch and communicate in part through antennae, thus allowing them to gather information about food sources, potential mates (pheromones), enemies, dangerous substances (e. g. a poisonous plant), nesting places and migratory routes (as in the case of the monarch butterfly). Second antennae uniramous. They vary widely in form but are always made of one or more jointed segments.

For example, the relative antennomere lengths for Tasmanopeltis grandis (top of page) are 2>3>6>(4,5). Antennae are bead-like in shape. Hadley, Debbie. The 13 Forms of Insect Antennae. Segments have a lateral projection, so they look like combs. Clavate - the segments become wider towards the tip of the antenna. I love this type of antenna! Capitate. 2) Pedicel: the second antennal segment or the one that comes just after the scape. This is the simplest model of antennae: long, thin and made of equally sized and shaped segments. However, the rest of arthropods only have a single pair of uniramous antennae. The terminal segments are enlarged only on one side to give the leaf-like shape. 4.

To see an example of lamellate antennae, look at a scarab beetle. Example: a very extended model among flies (Diptera). Technically, the capitate antennae of butterflies are also clavate because they are also clubbed, but they’re a special kind of club and get their own name (they’re capitate clavate antennae) Examples: Carrion beetles (order … Antennae are movable sensory organs on the head of most arthropods. Other organs, such as legs, palpi and even the ovipositor (organ for laying eggs) sometimes have sensorial cells. Epifita con fusti filiformi, ramificati e pendenti, di 25-35 cm. The most conspicuous of these features is clavate antennae. Geniculate antennae are found mainly in ants or bees. Example: sawflies (Symphyta, Hymenoptera), parasitoid wasps (Hymenoptera), some beetles (Coleoptera). Inside and in the base of sensilla there are sensorial neurons connected to the insect’s brain; specifically, a brain region known as deutocerebrum. Having a bigger antennal surface allows them to detect more suspended molecules, like pheromones. Aristate antennae are pouch-like, with a lateral bristle. Carapace not notched without apertures for antennae. Insects with plumose antennae include some of the true flies, such as mosquitoes, and moths. Example: Carrion beetles.

Examples: Carrion beetles (order Coleoptera). This antennae form is found most often in beetles, such as in carrion beetles. Setaceous antennae are bristle-shaped and tapered from the base to the tip. 3) Flagellum: the rest of antennal segments that form the antennae, which are individually known as flagellomeres. Except for chelicerates (spiders, scorpions…) and proturans (non-insect hexapods), all arthropods, either crustaceans, hexapods (diplurans, springtails -Collembola- and insects), myriapods (centipedes and millipedes) and the extinct trilobites, have antennae when being adults. Hairs on the margins and keels of glume III pointed and not clavate. threadlike. Adult carrion beetles feed on decaying animal matter or maggots. These flagellomeres are connected by thin membranes that allow them to move as a whole despite not having muscles. The segments of plumose antennae have fine branches, giving them a feathery appearance. Example: Cytherella. In chemoreceptorial sensilla, molecules bind with specific receptors that send nervous signals to the antennal lobe through the sensorial neurons. Clavate antennae terminate in a gradual club or knob (unlike the capitate antennae, which end with an abrupt, pronounced knob). Examples: Scarab beetles (order Coleoptera).

Antennae are microscopically covered with tiny hairs known as sensilla, which are not related with hairs found in vertebrates since they are made of chitin (as the rest of insect’s cuticle) instead of keratin. Hexapods (like insects), which seem to be closely related to crustaceans according to the pancrustacean model, seem to have just preserved the secondary pair of antennae typical of crustaceans. Epiphyte with filiform, ramified and drooping 25-35 cm stems. The antenna below at right could be described this way: Antennomere 6 widest; relative antennomere lengths 3>(2,6)>(4,5) , but the length difference between antennomere 3 and antennomeres 2 and 6 is very small, so (2,3,6)>(4,5) would also be reasonable.

Examples: Carrion beetles of order Coleoptera. However, this segment would have evolved into a reduced and inconspicuous piece, now being unappreciable. Because the segments are of uniform widths, there is no taper to filiform antennae. So, insects taste, smell, touch and communicate in part through antennae, thus allowing them to gather information about food sources, potential mates (pheromones), enemies, dangerous substances (e. g. a poisonous plant), nesting places and migratory routes (as in the case of the monarch butterfly). Second antennae uniramous. They vary widely in form but are always made of one or more jointed segments.
