Has anyone ever bothered to ask themselves that the ridiculous propagation of the idiotic ritual killing of every terrestrial arthropod by suburbanites throughout every municipality east of the Mississippi might actually be a major contribution to this outcome?

I'm pretty sure the ruralites kill way more arthropods since they spray much larger areas.

I don't have a clue what you're talking about, but then again I'm from west of that river. Mind elaborating?

Monsanto sells products to annihilate most insects to ensure monoculture lawns. Have you not seen that throughout America?

In California I haven’t seen much advertised in this regard. You’re saying it’s common elsewhere?

We planted milkweed at our home, 9 years ago in Colorado, but never saw any visiting Monarch.

Some milkweed came up next to my garage a few years ago. I let it go and it spread. This last summer I saw Monarchs around it a couple times. Once I thought I saw one lay an egg and later when I checked the plant, I saw what looked like an egg in that spot. I never saw any caterpillars. There are other insects that also like milkweed and I saw plenty of those.

We can help the humble Monarch butterfly by planting milkweed seeds: https://www.thebutterflyfarm.com/free-milkweed-seeds-0

There are many different species of milkweed. Please, only plant the species that are native to where you live. If you are unsure what species are native to your area, contact a local plant society, for example the California Native Plant Society, the Oregon Native Plant Society, etc., and ask them. They would be more than happy to help and can tell you where to buy seeds.

edit: here is what I would consider a better guide from the Xerces Society, with links to regional seed suppliers.

As it happens, I just got back from seeing the Monarch grove in Mexico. It's an amazing sight. When the sun comes out from behind the clouds and they all warm up and take off within a couple minutes, the air is so full of them that they darken the sky. And the mountain (in Michoacan province, about 2 hours by car from Mexico City) is beautiful and the people are friendly. If you've seen the Monarch groves on the Cali…

Note that there are multiple species of milkweed. If you find milkweed unappealing, look into other species. In the late 1980s/early 1990s, I found a couple of monarch pupae on some plants in the wetlands in my back yard. The plant stems were more stiff and the leaves less velvety than the milkweed I was familiar with in the local park.

I asked our local nature center if Monarchs only eat milkweed, why they would pupate on this plant. They identified the plant as https://en.wikipedia.org/wiki/Asclepias_incarnata , a variety of milkweed.

If it helps, milkweed is also known as "swan plant" due to the shape and colour of the flowers. Can help convince some gardeners to invest, if the word "milkweed" puts them off as it sounds unpleasant.

The native milkweed where we live is beautiful, and smells wonderful. It's also gorgeous in winter. I'm surprised it doesn't get planted more.

The assertion here by this activist group that the decline is due mainly to herbicides used on GMO crops doesn't seem to hold up on closer inspection:

In fact, herbicides are crucial in the fight against one of the major threats facing monarchs.

The invasive Dog Strangling Vine is related to milkweed and monarchs will mistakenly lay their eggs on it, where they fail to mature. It is a very prolific invasive species, and is significantly outcompeting milkweed in many areas.
