Now here's an interesting (albeit kind of disgusting) bit of information for you. If your kids find a corn worm while you're all shucking corn and decide to keep it as a pet in a jar with a bit of corn so it has something to eat and then put it somewhere that you don't find it until three weeks later when they go back to school, the worm will not live, but some of the corn will try to grow (along with plenty of moldy stuff). Gross. Thanks kids for the science experiment.
Interesting, no? I'm sure you'll find that information useful sometime in the future. Just file it under "nastiness".
