These insects look rather fearsome, with their antennae extended, rather like a scorpion's claws. However, this is all bravado. This species is a vegetarian. Known as the Dock Bug or Squash bug, it is the only one of the family readily found. I have several of them on my rhubarb leaves, at any time, throughout the summer.

The adult was the very first subject I used to try out my Printing Nikkor 105mm 1:1.

A last instar nymph was the test subject for my Leitz Summar 12cm 4.5, with 230mm extension on my EP-2, with manual, calibrated flash.

So this bug has been a subject at important moments.

These two instars have again been captured by the Printing Nikkor (FOV 17.5mm), with TTL RC, off-camera, diffused flash.

The close crops of the early instar were with the reversed Schneider HM 40 setup, with the same flash regime. There were two individuals, which looked identical to the naked eye, and present on the same leaf at the same time. However, one (first image)has come out in much more contrasty colours than the other one. This suggests it has recently moulted.

The first 5 images are of the youngest. I know the light sometimes looks harsh but it was diffused for all images and these insects are shiny at some angles.


The low magnification shots of the younger ones are not as hoped but give an idea of how these vey active insects appear in habitat.
