Epic Battle: Ant vs. Maggot
The ant (Aphaenogaster tennesseensis) was trying to pull the maggot from a patch of fungus. The maggot put up an epic fight despite being bitten over and over again. I watched for about 20 minutes. They were still at it when I left because it was getting dark. Rock Creek Park, Washington, DC, USA.
