Insect diversity falsifies the worldwide flood.

Hi again, Faith. Not specifically for insects, but for all lifeforms, the answer is on the order of 3825 speciation events per year since the flood. That, of course, translates to nearly ten new species per day simply to get the minimum ~10,000,000 species alive today. (The assumptions are based on the creationist book, "Noah's Ark: A Feasibility Study", which claimed approximately 8500 species on the ark itself.) Hyper-evolution indeed.

Yep. Not only that, but the figures assume such hyperevolution has/is occurring right up to the present. Now, if we assume that written historical records (say from early Greek or even Roman times) would have at least noticed new species popping into existence on a daily basis - even if we're just talking "microevolution within a kind" (whatever the hell that is), then the actual rate jumps to almost 7000 per year, or 20 species a day until the hypermacroevolutionary mechanism came to a halt. Now THAT'S amazing...
