Biting Midges (Certaopogonidae)
Minute size (usually felt rather than seen!)
Also called “No-see-ums” and “Sand Flies,” these tiny blood-sucking Flies are altogether too common at the beach. So small that they can pass through window screening, they are best discouraged with a liberal dose of insect repellent.
Crane Flies (Tipulidae)
Resemble overgrown Mosquitoes Extremely long, threadlike legs
Crane Flies are associated with the wet, swampy areas behind the beach. In spite of their mosquito-like shape, they can’t bite.
