But major tropical events such as Tropical Storm Debby awakened the dormant galinipper eggs, and scientists are expecting a boom in the next few months.
The galinipper can penetrate through layers of clothing. It will bite pets -- even fish -- out in the wild.
"It's about the size of a quarter. ... It's about 20 times bigger than the sort of typical, Florida mosquito that you find," says Anthony Pelaez of the Museum of Science and Industry in Tampa. "And it's mean, and it goes after people, and it bites, and it hurts."
Said Pinellas County extension agent Jane Morse: "It's huge. And it hurts.
"In an urban area, it's not really their habitat, so we probably won't see them in the city so to speak," Morse added. "But if you live near a pasture-type of an area, a grassy area that floods, then that's where you would see these mosquitos most likely."
