The tiny brown stink bug has been reported in 33 states so far this year. They get their name due to their smell of decaying garbage when they are squashed–and they lay 30 eggs a year! It seems to be spreading from its usual home along the mid-Atlantic coast to states throughout the US (due to climate change?) While they are not dangerous (just unpleasant), they DO bite, and they like to infest beds and sofas.
Roaches, that is: Many insects of today are tiny, compared to their ancient ancestors, but the biggest cockroaches that have ever lived are living in your kitchen today–they’re the size of steaks–and scientists are trying to figure out why. Many insects grow larger when the air is more oxygen-rich, because bugs breathe through their skin.
