This would be a new prey mob, it can be caught with.. 2? insect collecting
When it spawns it crawls around 1 tile at a time and it's just a caterpillar
After a few days it will change into a cocoon form you can't collect for 1 or 2 days. After that it is a butterfly-moth looking thing.
Maybe the final form needs 1 more insect collecting than the caterpillar
It will spawn in swamps, jungles, and grasslands
Feel free to suggest other name ideas
