A movable, articulated organ of sensation, attached to the heads of insects and Crustacea. There are two in the former, and usually four in the latter. They are used as organs of touch, and in some species of Crustacea the cavity of the ear is situated near the basal joint. In insects, they are popularly called horns, and also feelers. The term in also applied to similar organs on the heads of other arthropods and of annelids.
modified paired appendages used for touch and chemical sensation (taste; smell)
The second, paired, cephalic appendage. It consists of four short, robust, proximal segments, two long, intermediate segments, and a long series of tapering annuli, called the flagellum. The third basal segment bears a smaller, lateral appendage called the antennular scale that is homologous to the exopod in other Crustacea.
a long, slender organ or feeler located on the head of an insect, crustacean or other arthropod; or any long, slender rod used for gathering or transmitting information.
a jointed, moveable part of an insect's body through which it may touch, smell or taste; antennae grow in pairs from insects' heads
The long segmented appendages located behind the eyestalks. These allow the crab to interact with its environment by touch and chemoreception.
A sensory structure on the front of the head, which is thread-like on Hymenoptera (Fig. 62A), and club-like on Diptera (Fig. 63).
( antennae, pl.): A pair of segmented appendages located on the head above the mouth parts; usually sensory in function. (Fig. 1)
one or two paired segmented appendages arising from the anterior part of the head, anterodorsal to the buccal mass
a pair of segmented sensory organs, one on each side of the head, used for sensing touch, taste, and smell. Commonly called "feelers".
one of a pair of mobile appendages on the head of e.g. insects and crustaceans; typically sensitive to touch and taste
a jointed appendage that grows from the head
a sensory organ found on the head of insects
Sensory organ on the head for hearing and smell.
The usually club-shaped appendages on a butterfly's head that serve as sensory organs.
The clubbed sensory organ found in pairs on the head of a butterfly.
A slender feeler located on the head of some animals. The feeler contains sense organs.
(more than one = antennae) Main sense organ on insects, crustaceans, and some other animals. Antennae are used to collect information from the environment, including the location of food sources and possible dangers.
(plural: antennae): Elongate sensory structure located between the stemmata and clypeus or labrum near the bottom of the head of a caterpillar (see Figure 3).
The paired sensory organs, borne one on each side of the head.
The pair of sensory appendages on the top of the head, also known as feelers.
elongate sensory structure just forward from the eyes.
One of a pair of "feelers"on an insect's head. (plural: antennae)
(plural antennae): A feeler; an appendage, sensory in function, that occurs in pairs on the heads of crustaceans, insects, and certain other animals.
One of two long segmented sensory filaments located on the head of the bee, which enable bees to smell and taste.
Elongated, movable sensory structure found on the head
A paired, segmented sensory appendage of the head between the compound eyes, which consists of three segments having intrinsic muscles (see also scape, pedicel, and flagellum).
A pair of segmented appendages located on the head above the mouthparts and usually sensory in function.
one of a pair of slender, movable, segmented sensory organs on the head of insects, and other arthropods.
Long appendages found behind the eye stalks
(noun, plural: antennae) - one of a pair of slender structures located on the head of some insects. Butterfly antennae are used for balance and for detecting smells and wind speed.
jointed, flexible sensory appendages on head of a crustacean or insect (lobsters, like all crustaceans, have two pair); in Huxley, however, it often refers specifically to the second (typically larger) of the two pairs of antennae in crustaceans
whiplike, generally long sensory organ arising from anterior region of cephalothorax.
one of pair of jointed, flexible sensory appendages on head of crustacean or insect
The clubbed sensory organs projecting from the front of the head.
a pair of appendages on the head of an insect used as sensory organs
(plural antennae) The sensory organs on the head. Stag beetles have two antennae or 'feelers' with a characteristic shape at the end, which is the same for all the beetles that belong to the Lucanidae family. It is with their antennae that stag beetles pick up important pheromone signals.
One of a pair of sensory appendages on each side of an insect's head.
Paired segmental sensory appendage on the head, composed of the scape, pedicel and flagellum. [drawing
Antennae (singular antenna) are paired appendages connected to the front-most segments of arthropods. In crustaceans, they are biramous and present on the first two segments of the head, with the smaller pair known as antennules. All other arthropod groups, except chelicerates and proturans which have none, have a single, uniramous pair of antennae.
