While the evolution is indeed slow, I was trying to point out that there are other ways to introduce new species, that are not slow.
>problem that exists independently
yes, of course, but... if new species in small amounts are introduced to an ecosystem there is relatively high probability that they might not survive in that ecosystem.
Now if there was some void in that ecostystem, the chances of that new species could be higher since their competition was removed/reduced. This of course requires some kind of coincidence - when the species accidentally introduced to the ecosystem can take over the place of moths being reduced. Since there are so many variables I believe it is close to impossible to asses the probability of such coincidence. I assume that this probability is very close to "unlikely" but still non-zero.
