Antlion:

These unique insects are hunters and they dig holes in the sand and when ants or other unsuspecting insects come along, the sides of the cone collapse and they end up at the bottom where the antlion is waiting and sucks the fluid out of them and then flips the dried carcass out of the cone waiting for its next victim. 

Oddly enough I have known people who have the same traits as the antlion. Fortunately they are only few in number but the pattern is the same. Strange how some people mimic insects.
