The secret about lice

On December the 6th I got lice on my head. I was curious to see what it was. So me and my Dad took two lice that I had on my head and put it under the Foldscope. I learned lots of new things about lice. I learned that lice are insects because they have six legs. I saw that the antenna had five brick-like things in the adult louse and four brick like things in the young-ling. I read they are called flagellomeres. I saw that the lice digested my blood in its gut. In the microscope I saw that there are two claws on the legs. One was big and shaped like a hook and the other one was small and shaped like a baby hook.  It looked like a thumb and the index finger.  I learned that when the louse is dead the blood becomes dark red. From the two lice, I saw that the big one and the small one looked a bit different from each other.

I decided to draw all the parts of the big and small louse using a projection. If you look below my pictures are there.

Happy New Year.

    Truly truly inspiring work @Aditi. The level of details of your drawings is absolutely spectacular. I really love the idea of joining fields of view in the last photo.

    Isn’t it amazing that lice were some of the very first things that were observed; and your drawing is also an inspiration of some of the most famous drawings via a microscope – in the book Micrographia. (

    I wonder how you felt when you saw your own blood being digested. When I first saw a sand fly feeding on me – I had a very strange reaction to it. Watching my own blood in another animal, made me somehow connected to this bigger process of life. You might enjoy my old post here:

    Keep up the amazing work. Happy new year.

    Dear Manu uncle. Thank you for your comments on my lice post. When I saw my blood in the gut of the louse, I was surprised that my own blood is digesting in another insect. I also felt scared.
