TinyTuesday: Living on the Edge

I didn't notice that my tiny Red Harvester Ant was carrying something until I saw it on my computer.  The ant is only about 5mm so whatever she caught is really tiny and I can't begin to identify it.  It looks like she is on the edge of a cliff but it is really only a small pebble.  :-)
Thanks to osuzanna for hosting the TT challenge and giving great tips on macro photography in her journal!
