[Leps-l] NYTimes article on the NABA butterfly park

[Dana, Robert (DNR)]

Those migrating butterflies may not--probably did not--spend their larval development in the area where observed. May well have spent this time a little farther east where row-crop ag and insecticide application drops considerably. What has been reported regarding the overwintering numbers in Mexico this year?

Most people familiar with the sudden decline attribute it to an external factor,
like near surface water contaminations by noenicitinoids... or airborne drift .

Some butterflies continue to be abundant where neonicotinoid insecticides
are used heavily on a region wide scale; e.g. on the corn & soybean
croplands of the upper Midwest.

Late last August 2021 I shot this video of monarchs migrating Southwest in
south-central Minnesota at the rate of 20 butterflies per minute:

And in Sept. 2020 a farmer in south-central Minnesota shot this video of
hundreds of monarch nectaring on some Liatris ligulistylis flowers
he planted. https://youtu.be/CDun70cjAK0<https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fyoutu.be%2FCDun70cjAK0&data=04%7C01%7Crobert.dana%40state.mn.us%7C96d0efdf13d74a15125e08d9ef7118cf%7Ceb14b04624c445198f26b89c2159828c%7C0%7C0%7C637804092636370726%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000&sdata=0xXI4DovZRHmQS63YefGPa%2B2Hs7ege19qdHrvwWCtM8%3D&reserved=0>
