Butterfly needles are short, small diameter needles attached to a flexible tube. The needle has two rubber wings on either side that allow the phlebotomist to easily hold onto or move the needle. The tube is attached to a rubber boot, which attaches to the blood collection tube. Blood taken from the wrist, hand and foot are usually done with a butterfly needle, which allows the patient some sort of movement without knocking the needle out of place.
