Neivamyrmex opacithorax - Army Ant Queen
Arizona, USA

A queen Neivamyrmex army ant.  Her enormous abdomen houses ovaries for egg production.  Queen army ants are among the most fecund of all insects, as army ant colonies may have tens or  hundreds of thousands of worker ants (such as the small ant pictured riding on top) and the reproduction is the work of a single mother queen.
