Antennae (sg.: antenna) (sometimes referred to as "feelers") are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
This is extremely useful when the antenna is at a very high point, and the edge of the signal is likely to miss the target (broadcast audience, cellphone users, etc.) entirely. With electrical tilting, front and back lobes tilt in the same direction. For example, an electrical downtilt will make both the front lobe and the back lobe tilt down.
The members of the Cerambycidae (Longhorn Beetles) family are named for their long antennae, sometimes exceedingly so. The antennae of males are usually longer than those of females, and often the antennae are attached to the head in a strange notch at the front of the eye. Styloxus fulleri is a smaller species, at about 12–13 mm in length.
Members of this family are commonly called round fungus beetles due to the globular shape of many species, although some are more elongated in shape. They are generally small or very small beetles (less than 10 mm in length) and many (but not all) species have clubbed antennae .
In a few beetles within the same subfamily Lepturinae, the males establish copulation by mounting the females with their head placed over the female's and grasping an antenna with their mouthparts. [9] They pull on the antennae until they are copulating, with the male's abdomen probing down to make contact with the female's ovipositor.
A once-invited guest, Asian lady beetles are now considered an invasive insect in the U.S. — and they may be an uninvited guest in your home right now as the insects swarm, searching for a warm ...
Anthrenus carpet beetles are small beetles a few (1.8-4mm) millimeters long with a rounded shape. Their antennae bear small clubs at the end, which are larger in the males than in females. Many have a delicate pattern, with a dark body covered in colorful scales of various brown, tan, red, whitish and grey hues.
Adult drugstore beetles are between 2.5 and 3.5 millimetres (3 ⁄ 32 and 1 ⁄ 8 in) long and have a reddish-brown colour with a cylindrical body. The beetle looks superficially similar to the cigarette beetle, another ptinid beetle regarded as a pest, but can be distinguished under magnification by the lack of serration on the antennae and the presence of clubbed segments on the last several ...
