Giant mosquitoes with blood shots like a knife make many people confused.
The Gallinipper mosquito with scientific name Psorophora ciliata possesses a painful injection like a knife.
This wildly aggressive mosquito is about 20 times larger than a normal species so the danger level is even greater.
Females often lay eggs on the moist soil near the shore where water is flooded with tropical rain.
The eggs will wait until the flood season to grow.
Mosquitoes Gallinipper lived in Florida longer than native people but never carried a contagious pathogen except a bone-stinging pain.
Adult mosquitoes have wingspan of 7-9 mm.Most are yellow, black heads, white belly, with bright yellow stripes running down the body.
In particular, males have a pair of rough beards to "tone" their children.
Rhombus eggs are about 0.8 mm long, 0.4 mm in diameter and can lie on land for a long time.
After hatching, these newborn Gallinipper were very fierce to attack smaller mosquito larvae, even tadpoles.
With this characteristic, giant mosquitoes are being studied to be used as biological weapons to kill larvae, intermediate organisms that infect humans.
The time when mosquito eggs grow to adulthood is only about 6 days.
