A "tipple mosquito" is a common colloquial term for a crane fly, a large, long-legged insect often mistaken for an oversized mosquito. Despite their resemblance to mosquitoes, crane flies are harmless and do not bite humans or animals.
Understanding the Crane Fly
Crane flies belong to the family Tipulidae and are characterized by their slender bodies, exceptionally long legs, and delicate, transparent wings. They can vary in size, with some species reaching up to 2.5 inches in length, making them appear quite intimidating. However, adult crane flies typically live only for a few days, during which their primary purpose is reproduction.
These insects are known by many regional and informal names, reflecting their diverse appearance and behavior. Some of their most common aliases include:
- Tipple bug: A widely used term, especially in some regions.
- Mosquito hawk: This name can be misleading, as while they might prey on very small insects in some cases, they are not primarily mosquito predators.
- Flying daddy long legs: A descriptive name due to their long, spindly legs reminiscent of daddy long legs spiders.
- Gully nipper
- May-fly (though not a true mayfly)
- Skeeter eaters (another misnomer, as they do not eat mosquitoes)
Why They Aren't Mosquitoes
Despite the "mosquito" in the informal "tipple mosquito" name, crane flies are distinctly different from actual mosquitoes (family Culicidae) in several crucial ways:
- Mouthparts: Adult crane flies possess undeveloped mouthparts and cannot bite. They feed on nectar or decaying organic matter, if they feed at all, or simply survive on fat reserves from their larval stage. Mosquitoes, particularly females, have piercing-sucking mouthparts designed to feed on blood.
- Behavior: Crane flies are clumsy fliers and are attracted to light, often found fluttering around windows. They pose no threat to humans or pets. Mosquitoes are agile fliers known for their biting and buzzing.
- Lifecycle: While both go through complete metamorphosis, their larval stages differ significantly in habitat and diet. Crane fly larvae (known as "leatherjackets") typically live in moist soil, decaying organic matter, or aquatic environments, feeding on roots, decaying plant material, or small invertebrates. Mosquito larvae are strictly aquatic and filter-feed on microorganisms.

Ecological Role and Impact
While adult crane flies are largely harmless, their larvae, sometimes called "leatherjackets," can occasionally cause minor damage to lawns and turf by feeding on grass roots, especially in temperate climates. However, in most cases, their presence is not a cause for concern.
Crane flies also play an important ecological role:
- Decomposers: Their larvae contribute to the breakdown of organic matter in soil, aiding in nutrient cycling.
- Food source: Both larvae and adults serve as food for various animals, including birds, bats, and other insects.
- Pollinators: Some adult crane fly species may inadvertently aid in pollination as they move between flowers seeking nectar.
