Wow, this is excellent! There's a few additional cautions I heard in a talk from a rep of the Xerces Society for protecting invertebrates [1]. One is that some of the new pesticides are systemic and durable. This means that you can buy a plant from a nursery that is supposedly bee- or butterfly-friendly, but if it was sprayed with one of these pesticides in it's growth, it now will actually be deadly to the very insects you are trying to attract and nurture. Also, many of the bred variants of the plants may look nice, but actually be incapable of growing the nectar, etc. that supports the insects we're trying to nurture. So, best to seek out the original native cultivars and organically grown (or at least with known transient non-systemic pesticides). Also check out the Xerces society and its materials -- they're a wealth of knowledge on the subject. [1]
