The acorn weevil and its drilling Mechanism

The acorn weevil lives on the acorns of an oak tree. There is a moderately long snout on the head of this insect, which is actually longer than its own body. At the end of this snout, it has small but extremely sharp saw like teeth.

At other times, the insect holds this snout horizontal, in line with its body, so that it does not interfere when it walks. However, when it is on an acorn, it tilts this snout towards it. Then the insect looks very much like a drilling machine. It leans the saw-like teeth at the tip of its snout against the acorn. The insect turns its head from one side to the other, moving the snout, which starts to drill the acorn. The head of the insect is of a perfect design for the job and displays an extraordinary level of flexibility.

While drilling with its snout, it also feeds on the fruit inside the acorn.
