Playful Four Cartoon Insect Characters

Create a playful illustration featuring four cartoon insect characters. Modify their designs as follows:

1. Character 1: A blue beetle with polka dots and shorter legs, giving it a stubby appearance.
2. Character 2: A tall, slender grasshopper with elongated antennae and a bright orange body with wavy patterns.
3. Character 3: A cheerful caterpillar with a green body that has vertical stripes and oversized round eyes.
4. Character 4: A shiny, winged ladybug with a purple body and starry designs on its wings.

Incorporate whimsical elements in the background, like swirling plants and oversized flowers, without any brand references. Use a fun, coloring book style.
