Locusts and honey

Matthew 3:4 - John's clothes were made of camel's hair, and he had a leather belt around his waist. His food was locusts and wild honey.

How many locusts are there in one serving? What I'm getting at is this: How many locusts did John have to eat to survive out there? Were the locusts plentiful or scarce? Were they hard to catch? How much honey was available? Was it easy to find? Was there any competition with the local wildlife?

I wonder how long John maintained this diet? Was this his only food in the wilderness or just the unusual items that people mentioned first and most often when John's name came up in the conversation?
