Lesser House-fly


 I think this photo is of a lesser house-fly.  It is smaller than the common house-fly and there is a difference to the vein pattern on the wings (Collins Complete Guide to Irish Wildlife).  A little browsing on the internet reveals that their full life-cycle is generally between 18 and 21 days!  Apparently they survive longer in cool conditions, so I am guessing the Irish ones live a bit longer!!!

In this photo, I liked the way the colour of the eyes matched the stripes on the leaf.  It can be technically challenging to get a good photo of an insect.  The required closeness to the subject results in a shallow depth of field that can blur parts of the insect.  It is important to get the eye in focus and try keep the body of the insect on the same plane.  The angle I held the camera at caused some areas to be out of focus, but I wanted some of the front of the head to be in the shot.  Settings used were 1/160 sec with f/8 and auto ISO gave 400.  If I was to take the shot again, I would increase the shutter speed as the little movements of the insect can cause lack of focus and the low ISO facilitates a higher speed.  Unfortunately, this lesser house-fly flew before I could adjust the settings.  I used my Canon 100mm macro lens on a Canon R6 mirrorless camera.

The photo was taken in Hunting Brook Garden, which is open to the public and well worth a visit.  Jimi Blake’s horticulture qualification and love of plants has created an oasis in the Wicklow Mountains at Lamb Hill.
