So it's kinda self-explanatory. But here are the rules or else it wouldn't be a challenge...
1: You must create, for your starter pair, a Rogue Male (Derp snout, deformed paws, etc.) and a Ladybug (Red fur, black small spots, wings, antennae). Only if you can't find a suitable Ladybug mate (any red-furred Nicheling) you can mate with the rogue male.
2: ONLY the Ladybugs in the tribe can mate, unless: A: you have no other compatible males/females B: you see a wanderer with some particularly good genes.
3: If you have a child who looks more like the Rogue Male, either use the console to give it at least red fur, or set it to the side.
4: If a female mates with a rogue male, either banish her from the tribe (cruel leader), set her to the side (regular leader), or rank her to an Alpha, aka leader, and have the leader declare she is his/her mate/companion (kind leader).
5: Once a ladybug has her child, her, her child, and her mate (optional) move to a different part of the island with at least one line of darkness between them and the tribe center.
6: Try to only eat leeches, snails, etc. Think of those as aphids. Rabbils and berries can also count as aphids, but only if you can't find any bleeches or snails.
7: I recommend Grass Mingle, Grass Adventure, or Sleepy Reeds, really any island that has swamp, for the playthrough.
Goal: Your goal is to have a tribe of 20-30 Ladybugs completely: Red Fur, Antennae, Wings, Black Small/Large Spots, even No Pattern.
