This article gives the latest numbers tallied of the Monarch butterflies overwintering in California. Those numbers are *drastically* down, and the causes listed are pesticide use, loss of winter habitat, ... the usual suspects. What surprised me was the information that milkweed plants bought from nurseries, by well-meaning gardeners, tested positive for pesticides in their leaves even before gardeners bought them! For those of us who refuse to use pesticides/insecticides of any kind, this was a shock!!
Please read this article. There's more information that needs to be shared and highlighted, if we're going to turn things around for the Monarchs and other insects who need our help.
