i have a suggestion:
The aim of the game is to eat all your opponents herbivores and plants/ have the most territory
There are three types of card: territory, carnivore and herbivore. The territory cards represent different habitats and have different plants.
Only cetain herbivores can ''eat'' them. When you place a herbivore card on a territory card ( you can only place herbivores on a territory with plants it can eat), it is occupied and no other insect can move on it, unless the herbivore is ''eaten'' by a carnivore ( only certain carnivores can eat certain herbivores).
When your opponents herbivore is eaten, you can occupy it with your own herbivore. Certain herbivores can only be ''eaten'' by one or two carnivores beacuse in real life they have chemical defences. You can expand your territory by placing more herbivores and territory cards.
Carnivores will eat different herbivores over their lifetime( to make herbivores/carnivores metamophose, you need to have a card that allow it to do so and the card representing the next stage/instar
Example: I put down Tropical Rainforest Card and i put a caterpillar on it. My opponent sends a hierodula to eat it So that card belongs to my opponent T_T I put down postman butterfly caterpillar but the hierodula can't eat it becos it is chemically protected. So if i have postman butterfly pupa and a '' Move to next stage in life cycle'' card, it will become a pupa.
