A Striated Deer Fly (Chrysops striatus) has a lunch date with my arm as I go about my late morning wetland walk. Deer flies and horseflies can be my nemesis while doing wetland work. I am not too bothered by mosquitoes compared to many, but these flies bite you and then lap up the blood; it is hard not to be bothered by that. #deerflies #flies #wetlands #parasites
