Species is little more than a convenient way to classify creatures that typically breed together and share a habitat. That has little value as far as Creationism is concerned, because what was created was "kinds", not species. We know, for example, that different species of cats (like lions and tigers) can breed together and produce offspring. Such offspring are usually infertile, but they ARE produced in nature on rare ocassions.
Critics often set up a straw man concerning Noah's Ark, saying that there's no way every species alive could have fit on it. But that wasn't necessary. Let's take dogs for an example. It's plausible that all of the worlds modern dogs, foxes, wolves, dingoes, hyenas, and jackals are descended from a single pair of dog-like creatures that survived on the ark. They would have had a very robust genome, with all of the information needed to produce each of the 'species' listed above. As population groups spread accross the globe, certain genetic information was lost over time in each group, leaving other genes to be expressed. That is a process that creationists call speciation, and it's NOT the same as evolution because it represents a LOSS of genetic information over time rather than a gain. Note that it's also testable, simply by breeding, say, jackals and wolves together, and seeing what happens.
That is why I don't fret over the loss of a single variety of beetle or frog in a rain forest. Those populations have already lost so much of their original genetic information that they were on the verge on extinction already. It would actually be better to 'cross-breed' some of those popluations. That would have the effect of putting fragments of genetic information back into one large pool, making it more robust.

note the consistent anti-realist position with regard to biology that runs through almost every comment. hey, they're just deteriorations from the pure idea of Gawd! Fuck em, who cares about bugs and stuff! Pass the communion wafers.
