Hi plasjas I'm glad you put more pics on that site. You asked about The Bug Book- The story was written by Edward Gorey, and he illustrated it as well. Here is the text:
There were once two blue bugs.
They lived in a teacup which had a piece missing from the rim.
They were frivolous, and often danced on the roof.
There were also three red bugs, who were cousins of the blue bugs.
They lived nearby, inside a blue bottle, which made them an interesting violet colour when they were at home.
They were house-proud, and frequently polished the glass on both sides.
There were also two yellow bugs, who were cousins of both the blue and red bugs.
They lived a little further off, on the topmost leaf but one of a plant.
They were pensive, and sometimes sat on the topmost leaf and looked into the distance.
All the bugs were on the friendliest possible terms and constantly went to call on each other
And went on excursions together
And had delightful parties.
And then one day a black bug, who was related to nobody, appeared in the neighborhood.
The other bugs were dubious, but nevertheless made an attempt to be friendly.
It was not a success.
After that, the black bug broke up their parties.
And waylaid them whenever they went visiting.
Social life came to a standstill.
A desperate secret meeting was held.
At last they decided on a plan.
They next morning they rushed from their homes and dashed to the top of a certain cliff.
The black bug followed them to the foot of the cliff, where he jumped up and down, and shouted personal remarks.
Meanwhile, they were pushing a large stone towards the edge.
It went over, and almost at once a horrid noise came from below.
Presently they descended and rolled aside the stone.
The black bug had been squashed quite flat.
They slipped the remains into an envelope
And left it propped against the fatal stone to be mailed.
After which they had a party compete with cake crumbs and raspberry punch
And everyone enjoyed himself immensely.
