Inverted frutterfly is a period-4 oscillator, and is among the smallest true-period-4 oscillators not based on mold.

Much like the frutterfly, it can nontrivislly react with many small still lifes as to produce larger period-4 oscillators.

Relation to other oscillators

Inverted frutterfly is easily seen to be closely related to frutterfly, in which both halves are mirrored instead of rotated.
