The horseflies this year have been notably numerous,
perhaps because of the mild winter and hot and dry conditions.
I see them everywhere - in limbs of trees,
hanging on the window grooming,
or buzzing at my head when swimming and aiming to take a chunk out of my arm.
The females of these true flies can inflict a rather painful and quick bite with their razor sharp mandibles and are in need of a blood meal in order to reproduce.
On a more positive note,
they are also play a role in pollination as they also feed on nectar and pollen.
