I read this as a direct attack, although the parent's argument is clear. Let's say you trap 2 in 10k insects, which sounds high. If 50% of those insects had a slight evolutionary advantage against traps (which sounds a lot), that the two that did get caught didn't possess. Great, they now have a 0.02% evolutionary advantage. My point is: I assumed a lot of things, yet came up with a tiny advantage. I don't think (didn't compute) this is going to do much difference in the short term (although long term, it could have a bigger effect). So yeah, as in your argument, Zs die of, but very slowly, and there might be other greater pressures fighting against this. Assuming the rates of my post, I'd be curious to see how much time it would take to achieve a meaningful difference in terms of population. (These catch rates are very high, and insects tend to reproduce quickly, so I wouldn't be surprised if it wasn't much).
