Giant Crane Fly
Tipula abdominalisAlso known as Giant Tipula
Giant crane flies emerge near shaded streams and woodland seeps during warm months, fluttering clumsily through the understory on delicate, oversized wings. Despite their intimidating mosquito-like appearance, adults are completely harmless and lack mouthparts capable of biting. The aquatic larvae play a crucial ecological role in river ecosystems by shredding fallen leaves into nutrient-rich organic detritus.
