Currently, where I live is going through one of those fascinating life cycles found in nature. Our trees are inundated with thousands of red eyed cicadas. Despite having experienced this phenomena several times in my life in various parts of the country, I am always amazed at how loud they are. This got me thinking about what that might be like if they were bigger…much bigger.
What the cutting locust left, the swarming locust has eaten. What the swarming locust left, the hopping locust has eaten, and what the hopping locust left, the destroying locust has eaten. — Joel 1:4

These wandering giant insects are normally only found in groups of one to four; however, if threatened they will start vibrating their abdomens, creating a noise that attracts more tettixi. Every round that a group of tettixi makes this noise 1d4-1 more will show up.
In addition to attracting more tettixi, this noise effectively acts like a Silence 15'r. spell — the noise is so loud that speaking and casting spells becomes impossible. Further, if there are ten or more in the same area making noise, the sound becomes so loud as to do damage to other creatures. Each round this sound will do 1d6 damage for every 10 tettixi in the area (half if a save versus dragon breath in made).
The abdomen of the tettix is highly valued because they can be used as a one-use Detect Lie device (it rattles if a lie is detected).
