These pesky little gals were our "greeting committee" when my family went to the beach in Florida. I snapped this photo before my brother swatted them as they munched on his leg! To be so tiny (<1/8"), these biting midges sure can cause a lot of discomfort. They have little piercing mouthparts that they use to drink blood; their bites are not painful, just highly annoying! Like mosquitoes, the females must have a blood meal in order to lay their eggs. Their bites can leave small red spots on the skin.
