Well, they are actually pretty interesting creatures! The larvae of the horseflies in Malawi, Africa display a unique design behavior. When the larva is ready to undergo metamorphosis, it buries itself in wet mud. This mud can crack and kill the larva, so the horsefly larva corkscrews itself down into the mud, creating a cylindrical chamber while the mud is moist.
Once underground and sealed up, the mud around the horsefly will crack in the sun, and because of the cylindrical tube the larva created, the mud will crack around the tube. Now the larva has reached its adult stage and can emerge from its tube, fully developed.
God programmed the horsefly specifically and intentionally!
