Nightmare Fuel, Day the Fourth. Are they all the same?

Here's a weekend Nightmare Fuel entry; a few quick lines of poetry, as I don't have my usual commute. Enjoy!

Are they all the same?
I can't tell.
The buggers all glisten
like oil on pavement.
all look
wrong


If I kill one, do the others care?
Do they
 have a bug funeral?
Is the bug colony
different or just
smaller?
Are they all the same?
Does losing one cost them
a thing?

Are they all the same?
Can they tell that we
are all
different?
