If you’ve ever swatted at what looked like an enormous mosquito, you may have actually encountered a harmless crane fly. Despite their appearance, crane flies—sometimes called "mosquito hawks"—do not bite, sting, or spread disease. In fact, most adult crane flies don’t even eat.

Crane flies are often mistaken for mosquitoes because of their long, thin legs and delicate wings, but a key difference is their lack of piercing mouthparts. Unlike mosquitoes, which feed on blood, crane flies spend most of their lives as larvae, where they help decompose organic matter in soil and water. Their presence also serves as an indicator of good water quality and provides a vital food source for birds, fish, and other insect-eating animals.

While crane fly larvae can occasionally damage grass by feeding on roots, adult crane flies are completely harmless. They are often seen near streams, ponds, and damp woodlands, and they are naturally attracted to lights—sometimes making their way indoors. If you find one in your home, simply guide it outside rather than squashing it.

Los Angeles County residents often see crane flies in the spring and fall, especially in areas with gardens, standing water, or outdoor lighting. While mosquitoes pose a public health risk, crane flies do not, so next time you see one, let it be!
