Do I need to report interest income from savings accounts that total less than $20? I never receive a 1099 from the bank.

I have 3 savings accounts and the total amount earned from interest fro mall 3 accounts is less than $20.  Do I need to worry about this income?  I usually add all 3 up and claim it as income but I never get a 1099 from the bank and I assume its because its not enough money to have to claim on my taxes..
