Here is two pics from this summer, I need to start again somewhere and here it is... This is a start.
The top picture is a melon caterpillar ... When I would cut up the watermelon so it had formed shapes that looked like the right caterpillar, very exciting, I think.
The picture below is a real caterpillar I run into in one of our beautiful islands in the Gothenburg archipelagos some weeks ago.
