I initially saw just a couple of these bugs feeding on my milkweed and thought they were pretty and harmless so I left them alone. Now, just a couple of weeks later, they have multiplied and are devouring my (scarlet) milkweed and leaving very little for the monarch caterpillars. Every day, I now have to spend time daily looking all over the MW and picking off the adults and the larvae to attempt to slow them down before they eat all the MW. If you see these on your MW, kill them immediately before they multiply out of control. Too bad, they are pretty bugs but not prettier than monarchs!

My swamp milkweed is stripped of leaves just as it began to bloom. These nasty beetles are everywhere. When distrurbed they drop to the ground and are hard to locate in leaf litter. This is my first year to have them and I don't want them back. Thankfully I haven't been trying to feed Monarchs or I might be in short supply.

Labidomera clivicollis strips the leaves and buds off any Asclepias curassavica plants that happen in my yard. When I am vigilant, and pick the bettles off, the plant has a chance of surviving to bloom; but this year I have been too busy elsewhere in the garden, and all I have left is three bare stems.

Swamp milkweed beetle showed up in late July in Olive Branch, MS. I had just purchased the milkweed on line and planted in May. Several branch tips were also covered in yellow egg looking stuff. I pinched the tips off and threw them out. Only noted 3 beetles total. I also have some butterfly weed (tuberosa) and have had it for two years. It gets mildew but never had beetles.

My Milkweed crop is devastated again this spring, just as the Monarch's are coming in. They eat everything except the roots and leave nothing for the Monarchs. I can collect two to three dozen adults any morning.

Found one adult on common milkweed, Asclepias syriaca, in Maryland.
Editing- I've had many on Swamp Milkweed; that's the first place I ever saw them in my garden. They much preferred the Swamp milkweed. In two years they killed a very hearty specimen.
