This photograph shows ants with ant brood.
Your challenge is not to identify the adult ants. In a fit of generosity, I’ll tell you what they are: Eciton hamatum army ants. No, your challenge is to identify the immature ants in that impressive brood pile. Hint: they are not Eciton.
Army ants sometimes stash prey in temporary caches before carrying it to the bivouac for their own hungry larvae to consume. This photo shows a cache we uncovered during our insect photo workshop last month in Belize. So, what are these army ants eating?
I will award 5 Myrmecos points for the first correct guesses of the identity of the prey ants.
The cumulative points winner across all mysteries for the month of October will win their choice of 1) any 8×10-sized print from my insect photography galleries, or 2) a guest post here on Myrmecos.
