I just discovered my puppy (about nine months) destroyed my winter slippers, so right now I'm extra cynical.

Ask Christians to what function God created the screwfly ( Cochliomyia hominivorax ), and if Noah willfully preserved screwfly specimens.

The screwfly maggot burrows into live mammals, and is the cause of myiasis or flystrike. The treatment for it is to cut the larvae out, which is extremely painful, but then so is having a screwworm eating you alive.

So hated is this critter that our scientists have actually considered if wiping them out would be too detrimental to too many ecologies, and as it is we produce neutered flies released in Panama to prevent them from getting too far into the US. Our scientific sector sometimes suggests we should totally finish the job. The screwfly is enemy to all mammal life including human beings.

The screwfly is mostly tropical but can survive far from the equator.

Ask them what lesson the screwfly was meant to teach, or what mystery it holds.
