Mosquitos Are Here

There were some biting mosquitoes in my yard this morning and a few got in the house. Later, working near Gee Creek, there were many more, swarming  and biting through a thick t-shirt.  I had swatted one earlier and took a photograph to ID it later.   Every few years, in the weeks before July Fourth, Ridgefield is plagued with mosquitos.  This could be one of those years.

 

From an article in Wikipedia, a drawing of a flood mosquito was a good match,  Flood mosquitoes lay their eggs on moist ground that is likely to flood later.  It has been very dry in Ridgefield from mid-April until today’s rain.  However, since the Columbia River has been high this spring, much of the refuge has been under water until a few days ago.  This could be the source of our mosquitos. In checking with the county mosquito control board, it was noted that the county does not spray for mosquitos.  Rather, they go after the larva by treating wet areas.  With much of the refuge being flooded  this spring, that would have been unlikely.

County mosquito control  states that there is no current threat of Zika Virus or West Nile Virus for Clark County residents.  So they are just annoying.  Vexans is derived from the Latin word meaning to annoy.    It’s early in the season but we will know soon just how annoying they are going to be.
