Well, they seem to kill themselves in a lot of creative ways...
Some caterpillars seem to lose their ability to contract, so they just keep lengthening, and eventually become immobile bars.
Others seem to have reproduction problems, and keep dividing until they become a huge ugly ball of fungus. Then they sit there in a unicellular cluster and do nothing...
Still others seem to break their tie-forming code, and form a pretty cool-looking "spider web", snatching any caterpillars that pass by and getting them tangled in it's mess. These guys not only kill themselves, but kill any caterpillars in tying range as well... which is annoying...
I guess these signs mean that the genome is too fragile? How do I make a genome more durable? I can't just make it have five copies of every gene, can I?
TY!
