We're taking our first, nervous steps in becoming bee-keepers and would appreciate some advice on a mystery substance we keep finding on our varroa floor. Apart from the odd dead mite, we have also noticed small fragments of a creamy-white powdery / crystalline substance for several days now. My husband thought it might be crystallised sugar syrup (we have been feeding) but he says it doesn't taste sweet on his tongue. Another thought we had was that it might be fragments of wax from comb building, but we took a sample today and put a match to it - it didn't melt so it's not wax.
Any ideas?
