In my balcony I had potted a tomato plant. While I was watering that plant I observed a leaf with white spots underside of the leaf.  I wanted  to observe those patches under the foldscope. While I was cutting the infected leaf I noticed small flies.

Then I put a piece of leaf under the foldscope but I couldn’t see clearly.

Later I caught hold of the insect and put it on a cavity slide and placed a coverslip gently over the insect. It is a white fly.  

I saw some black ones which may be the 3rd instar stage of the fly. 

Later  I peeled the lower epidermis of another leaf which was less infected and observed the following.
