Anyone strolling through an oak or beech forest in the northern hemisphere autumn (fall) is sure to find them—among the countless brown leaves scattered on the ground, some are still green (very green, in fact) in one portion (see photo).
If you look closely, you discover on this leaf a whitish spot, or else a winding trail. This is evidence that the larva of a tiny leaf-mining moth is living inside the leaf.
Leaf-mining species also occur among beetles and flies.
Why don’t the infested leaves turn completely brown like the rest? The amazing thing is that the larva secretes a hormone that keeps the surrounding area of the leaf fresh.
The cells of these ‘green islands’ still keep on photosynthesizing—making food from sunlight and carbon dioxide in the air. And the tiny larvae continue to live on the carbohydrates formed by this process, even after the leaf itself has dropped to the ground and died.
Only some time later do these larvae leave the leaf and enter the ground to pupate.
This presents some riddles for those who adhere to evolution:
Which were the first caterpillars to stumble on the idea of no longer gnawing the leaves from the outside, but crawling into their insides?
How could the larvae that were thus transformed know that their tree would shortly shed its leaves, so they could prepare for that event?
What would have happened if these mining caterpillars had failed, at their very first attempt, to synthesize the right hormone? It is only being able to secrete this hormone which guarantees that they can keep on living on the forest floor.
And what should we make of the fact that fossils of such leaf miners are already found in the ‘geologically oldest’ fossil leaves of the upper Cretaceous?
This one [see photo, arrow shows trail of leaf-mining moth] is from the Dakota sandstone in Kansas, USA, which is regarded as being from the alleged ‘age of the dinosaurs.’
At most, evolutionists will not be able to produce more than some flimsy ‘just-so’ story. It makes much more sense to believe that these obvious provisions by the Creator for His creatures were programmed into the insects from the beginning.

The evolution of man is often imagined to be a progression of knuckle-dragging simian creatures evolving/morphing into a fine upstanding bipedal man.
But virtually nothing is said of the symbiotic evolution of the flora food-chain of which those simians must have eaten in order to survive and procreate.
It is very hard to imagine a similar progression of pond slimes morphing into grasses on land and then into gigantic eucalyptus trees. The dearth of evidence supporting the imagined evolution of the great diversity of plant life that exists on earth today seems never to be questioned.
