A predecessor from the third G2_2 soup, which in generation 56 becomes an 11*14 44-cell predecessor of two frutterflies with debris, that is the most common origin in reflectionally-symmetric soups. (click above to open LifeViewer)
Frutterfly has occurred semi-naturally six times combined in the C2_2, G2_2, D4_x1 and D4_x4 censuses, which are no more conducive to orthogonally-reflectionally-symmetrical occurrences than C1.[3] In one of the G2_2 soups, the two halves don't interact at all, meaning that the equivalent C1 16×16 soup also produce a frutterfly[4], and making this object natural. Finally, a proper C1 occurrence was found by Charity Engine on 2023-12-06[5].
In alien rules, frutterfly has occurred in asymmetric soups in B37e/S23-q.[6]
