Journal Entry for Entomology 322
A pseudopupil is the illusion of a pupil on an insect's eye, caused by the same adsorbtion of light as in our own, wherein that lack of relection shows up as a black spot. Now in specific insects such as Mantises these are distinct, whereas in others they're hardly visible.
While back in Georgia, Acworth, on holiday last spring I was able to spot a Red Paper Wasp or P. carolina. Now as a rule wasps have quite good sight, as do mantises, but one has highly visable pseudopupils whereas the other does not. It would be interesting to find out if this has any impact on sight, or if it's a matter of simple evolutionary diversion within the structure of the eye.
