Some questions:
1. Why are they wild cards?
2. 2 feet long and swarm in the thousands? I would think the swarms would
have to be extremely rare or the entire continent would be bug food.
3. The descriptions says they never appear in small groups, but the game
stats is for a swarm in the size of a large burst template -- which strikes
me as a small group when you're talking about 2 foot long bugs.
