Strange, according to the most recent studies, monarch butterfly populations were down 27% last winter in Mexico. It's strange how these scientific studies don't coincide with Wente's personal observation that she's seen a few more monarchs! Also, while there was some initial speculation that glyphosate might affect monarchs directly, it has long been known that the real problem was the reduction in the amount of milkweed as a result of widespread herbicide use (along with deforestation in Mexico). 

As for neonics, most of the scientific evidence still indicates that they do, in fact, affect bees very significantly. A quick search using Google scholar pulls up dozens of scientific studies indicating this. The study that Wente cites simply notes that many other pesticides may also be reducing bee populations. That does not mean that neonics are not having an effect, although it may well indicate that we need to reduce or eliminathe use of other pesticides as well.
