[Leps-l] New Regional Monarch Nectar Plant Guides Now Available

[Bill Cornelius]

My brother in NZ raises monarchs just to release at his house, he says it's been harder the last few years because wasps have become too numerous. This includes hornets and yellow jackets which he can trap, but paper wasps ignore the traps. I'm wondering if there's something about global warming or agricultural development (such as wasp habitat or commercial tachinid flies) that's favorable to monarch predators.
