Bright-green caterpillars --- like all caterpillars --- transform over their lifespan into moths and butterflies. Countless varieties of caterpillars exist, all of which possess 12 eyes and 13 individual sections to their body. Caterpillars eat foliage for nutrients and the skin tone of the bright-green insects is attributed to a natural development which allows their colour to blend in with plants and leaves.
Find a Saddleback Caterpillar. Look for a bright, lime-green body with dark-brown wings. Identify up to three medium- to large-sized symmetrical black or white dots on the skin. Notice dark-brown bristles stemming from the front and back ends of the body. Search apple, blueberry, citrus plants, oak trees or sunflowers as natural habitats for the Saddleback Caterpillar.
Identify a Royal Walnut Caterpillar by its extensive 10-cm to 16-cm body length. Gaze at the varying shades of lime green on its wavy skin. Notice two distinct black dots above the head of the insect. Handle a Royal Walnut Caterpillar gently so you are not pricked by the brown antennae and black, thorny extensions along the head and body.
Notice the iridescent-like quality of the pale-green skin on the Green Cloverworm caterpillar. Look closely for the short and soft bristles lining the body. The faint-yellow colour of the bristles makes them almost invisible. The Green Cloverworm has 12 legs and no antennae or distinct colourful markings, making it exceptionally adept at blending into plant life.
