Floodwater mosquitoes buzzing 9.12

Posted in 2007 September

Not all mosquitoes are created equal.

Just step outside and meet up with a species that hasn’t shown its face—nor its sting—much recently, and certainly not in the abundance we’re seeing now.

Of the 60 species of mosquitoes that live in Michigan, a few belong to the class known as floodwater mosquitoes. Remember the heavy rains of August? The fruit of that flooding has arrived.

Dr. Edward Walker, a Michigan State University professor who studies mosquito biology and control, said the most common floodwater species in this area are Aedes vexan and Aedes trivittatus.

“Both of those are on the wing now in very large numbers,” Walker said. “It’s all a consequence of the rainfall patterns we’ve had in August.”

Trivittatus is the smaller of the two and Walker guesses that’s the one irritating people in this area. Many species appear a little wishy-washy about their dinner; not so with the aggressive trivittatus.

“They just hone right in and let you have it,” he said. “There’s no reticence.”
