First i saw them under my bathroom slab. They stick to the walls and the day and at the night they fly towards the light. why is this ? i found them only in my bathroom. they were not in any other room.

you can look at them. they are under my bathroom slab

first it looked like they are dead but not. they were living. they were moving and flying you can see it in this video

what type of insects are they? what is their name?

HOW I MADE MY SLIDE: First I caught them in my zip lock packet. it was very easy as they don’t fly with a great speed. then i took them in my freezer and took a picture of it. you can see below.

Then I made a slide of it.

OBSERVATIONS: I observed that it looked like a small fish which is transparent. it had very small eyes and we could look inside the body of that organism

New update for wings and antenna.
