Play all audios:
CRANE FLIES look like giant mosquitoes, but they’re not. Some people think they eat mosquitoes — hence the nicknames “mosquito hawks” and “skeeter eaters” — but they don’t. What they do is
fly around crazily like creepy-crawly bumper cars, bouncing off walls, ceilings and especially lights — like the porch light at your house. So say San Diego County officials, noting the
spring return of the critters after a wet winter. Even though they can freak people out, crane flies are absolutely nothing to be worried about, says Chris Conlan, the county’s supervising
vector ecologist. They’re harmless to people, Conlan said. They don’t bite and they can’t transmit any diseases. Conlan said we actually have crane flies around all year long, but we notice
them more in spring because it’s their peak breeding season after winter rains. However, he said we can probably expect to see more than usual this spring because we just had one of the
wettest winters we’ve seen in years. “We’ve already had people calling us (Vector Control) about them,” he said. “They think they’re big mosquitoes.” Crane flies are big for bugs. Their
bodies can reach an inch or more in length and their pole-like, spidery-long legs can make them seem even bigger. Conlan said if you’re worried that the bug you’re seeing is a mosquito,
there’s a fairly easy way to tell if it’s a crane fly instead. If it’s bigger than a dime, he said, it’s too big to be a mosquito. Conlan said crane flies are related to mosquitoes, but they
are not mosquitoes. They don’t bite; they don’t suck blood. In fact, most adult crane flies don’t eat at all. Those that do, he said, drink nectar. They’re not a public health issue like
mosquitoes or other vectors, which are the main concern for Conlan and the County’s Department of Environmental Health. Nicknames like “mosquito hawks” and “skeeter-eaters” are colorful but
totally inaccurate. Their wormlike larvae generally live in wet or moist soil, feeding off decaying organic matter. Some even live underwater. Adult flies don’t live long, about 10 days at
the most, unless they’re gobbled up before that by birds, lizards or other creatures. Because crane fly populations are high in the spring, and especially because they’re naturally drawn to
lights like the ones we have next to our front doors or porches, this is the time of year that crane flies can get into your house. “They’re very attracted to lights, so if you have any
around openings to your home, it’s very easy for them to get accidentally swept into the house,” Conlan said. “And then they end up freaking you and the cat out!” Again, crane flies aren’t
harmful. But Conlan said that if they really unnerve you or family members, you can turn off your front door and porch lights, or retrofit them with yellow bug lights, and try to limit your
outside lighting. That way, he said, fewer crane flies and bugs in general will be drawn to the lights, where they can fly into your house when you open the doors to get in. _— County News
