Coastal states in the U.S. Southeast and northeast Mexico are warm and humid enough to grow palms, so it follows that the Palmetto Weevil is found there as well. All Palmetto Weevils are not completely identical to each other. One popular color form is red with a black dots or line in the middle of the pronotum by the head, and five large black on the wing coverings. Another form is entirely black, and there are other individuals that fall somewhere between both variations. All have the long 'snout' and short, bent antennae that are typical of weevils. Their ‘snout’ is textured with tiny bumps. This is the biggest weevil found in North America and can grow just over 3 cm (just over an inch) long.
The young weevil, or grub, is destructive thanks to its feeding behavior. The plump, white, wormy grubs eat away at the crown of the palm which can cause it to fall off the tree. Cabbage palm and date palms appear to have broken their necks when this happens and the condition is called ‘popped neck’. Infestation of a palm may first be realized when young leaves start bending downward. It is difficult to treat a tree that is already infested, and it will likely die. In order to reduce a population, removing and destroying an affected tree right away kills eggs that were laid. Keeping palms healthy and quickly removing ones that are not, even if they are not noticeably infested, may help reduce the insect’s interest in the area

Antennae: Beetles have a pair of antennae on the head used for sensing.
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
Thorax: Holds the three pairs of legs as well as vital internal organs.
Elytron: One of two wing cases on a Beetle that protects its wings (plural: elytra).
Wings: Appendages used for flying and kept under the elytra until needed.
Abdomen: Houses organs related to circulation, reproduction, and excretion.
Legs: Beetles have three pairs of legs located at the thorax, numbering six legs in all.
