 Different parts of the cockraoch body were viewed under the foldscope to produce clear and sharp outcomes.


 Firstly, the mouth part of the cockroach was observed. The various segments of the mouth- the glossa, prementum and paraglossa could easily be distinguished. It appeared in shades of ochre and brown under the light.


 Next, the anal cerci of the cockroach was viewed. The anal cerci- an important sensory organ arose from around the tenth segment of the body of the cockroach. Fine hair-like structures could be seen arising from the anal cerci. Another feature of the anal cerci was the presence of light and dark segmented bands.


 The wing of the cockroach was kept under the microscope for observation. The wing, when viewed, appeared extremely textured with grooves. the wing was a glowing brown colour under the light.

 A cockroach leg was taken and viewed under the foldscope. The mid-section, joint and tip were seen clearly.


 The tip of the cockroach leg was dark brown, tapering and had hair-like structures at regular intervals.

 Next, the midsection of the leg was viewed. The mid-section was broad, with hair-like structures and faded from a dark brown colour to an ochre shade towards the sides.

 Lastly, the joint of the cockroach was observed. The joint was clearly visible and the segmented sections were precise.
