Is it a giant mosquito? Will it bite me?
Here are the common insects that are not mosquitoes, but fool many people every year in the cities:
Crane Flies aka Mosquito Eaters
Size: Larger than a quarter - at least 2 inches in length
If it's bigger than a quarter, it's NOT a mosquito.
These long-legged insects will terrify anyone who thinks they're bloodsuckers. Contrary to popular belief, these are not mosquitoes. Crane flies are also called "mosquito eaters" or "mosquito hawks." But when viewed under a microscope, crane flies do not have any biting mouth parts!
They do not bite. They drink nectar for sustainance.
Crane flies are a sign of a healthy ecosystem. They usually emerge out of the soil when warm weather follows a rain event.
Next time you see a crane fly, wave it outside. Let’s save those wing-crushing blows for the real threat: mosquitoes.
Size: 1/4 inch - Approximately same size as most adult mosquitoes
Mosquitoes in cities are unlikely to swarm. If you see small insects swarming, they're most likely midges.
Swarmers, not biters - This small insect is often confused with mosquitoes, but does not bite. They are routinely seen hovering in swarms on warm summer evenings. Our local mosquitoes in cities do not swarm in the same spot. Fortunately, midges do not make people sick, but are considered nuisances.
In our area, control measures are only necessary in extreme cases when numbers of adult insects are high. This insect also breeds in flowing waters, and tends to prefer the shallow, nutrient rich waters found in the storm drain systems in our area.
As they are physiologically and genetically very similar to mosquitoes, the larvicidal agents used for mosquito control (insect growth regulators) also work well to control midge populations.
