When there are no moths at the top left you can always drop into this same spot and needolin, no need to react as there is guaranteed to be at least 1 moth spawn between those 2. The lower left moths are close enough to consistently activate ASAP.
Then once they start to activate delay a bit (about 2 or 3 nail swings depending on if you mantle skip) and run across the platform towards left exit and react to whether you can see the moths moving up left or not to either drop or continue as shown.
For down exit this is about 0.2 slower than my fastest time without doing this setup, but this saves nearly a full second on left exit compared to greeding towards down exit any more.
