Ive been biten by a tiger mosquito?

It was black and a white mosquito. I was in the back helping my aunt moving the pool floaties and watering them down. Then all of a sudden I started feeling this sting and it was hurting and I look down on the lower back of my leg (not on my ankle) and I saw it there just sucking my blood I guess and I slapped it off. Should I be concern or is it just a regular mosquito bite. I'm in Norfolk,Virginia by the way. (I've put acohol on my leg and let it sit there. I taped it to my leg.. For about.. 2hours and I haven't tooken it off yet.)
