Huge Florida mosquitoes, that are 20 times the normal size, are expected to invade the area in large numbers this summer, experts say.

Last year's Tropical Storm Debby is blamed to awaken the dormant eggs of the large species of mosquito, the galinipper, according to scientists at the University of Florida. The female galinipper with hairy legs, feeds day and night are described as "notoriously aggressive."

"Because of the events last year, and the eggs laid, we can expect large numbers of these mosquitoes again," Entomologist Phil Kaufman, an associate professor with the University of Florida's Institute of Food and Agricultural Sciences said.

"We suggest people wear long-sleeve pants and shirts. Just doing that may not be enough for this type of mosquito; you're going to have use one of the insect repellants to dissuade them from landing."

Anthony Pelaez of the Museum of Science and Industry in Tampa said the galinipper bite "feels like you're being stabbed." Palaez said he suffered from the bits while working in the Amazon.

The insects that are native to the eastern half of North America is said not to be carrying diseases dangerous to humans like some of their smaller counterparts. It's less common in urban areas and tends to found near floodwater where they hatch.

They also feed on other mosquito larvae and even tadpoles and are most active at dusk and dawn.
