Th Weevils (Curculionidae) are the most numerous of all beetles and over 40,000 species have received names. Their distinguishing mark is the long snout, which has jaws at the end of it and is used for boring holes in the seeds, fruits, buds etc. in which weevils will lay their eggs.
The Palm Weevil (Rhynchophorus ferrugineus) lays its eggs on palm trees of various kinds. The larva tunnels in the trunk and crown of the palm and often kills the tree. This little weevil is a well-known pest amongst palm farmers and there have been many research and discussions on how to prevent and control this little “evil”!
