First I would like to make 1 small comment: Ladybugs (and their larvae) are predators that feed mostly on Aphids. Thank goodness there were Ladybugs on the Arc or they would have been over-run by Aphids in a year's time.
This is an interesting discussion, but a little puzzling to this newcomer. Are the creationists really arguing that evolution is the mechanism that accounts for the insect diversity that has supposedly arisen since the flood?? So they are willing to invoke evolution when it suits them even though they clearly do not understand the ToE? They seem to be ignoring the abundant insect fossils that exist for most living orders. For example, there are fossils that clearly show the developement, over millions of years, of wing veination characters that define the 5 families and 3 sub-families of living dragonflies. Are we suppossed to believe that these same features evolved all over again since the flood?
Monarch butterflies for example need living milkweed plants to survive. No living milkweed no monarchs. Do you suppose Noah was cultivating some milkweed on the ark for the monarchs.
Randy, you have not even addressed how the monarchs get transplanted from Mt Ararat to North America. Even for monarchs that is a bit far to migrate. Not to mention the literally millions of other species found on continents completely seperated from Turkey. It is not just insect species diversity, but their distribution that makes the flood story disagree with observable evidence.
Enjoy
