I enjoy the occasional brush with nature while on the golf course, as I am sure many others do also.  I came upon several antlion "nests" recently.  I always thought the insect was "ant lion" but Wikipedia told me it is antlion.  The larvae of the antlion build a funnel shaped trap in loose soil or sand.  Insects, typically ants, blunder into the cone and slide down to the bottom and meet their fate.  The things one sees while searching for that darn golf ball!
