Hello all; First an update on the 4 Monarch caterpillars I reported earlier in my front yard. They have all disappeared. I'd heard that butterflyweed, Asclepias tuberosa, doesn't offer the poisonous advantages of other milkweeds and can only surmise that some bird found them and chowed down. On a more upbeat note, I stopped by the house briefly this afternoon and noticed a female Monarch flying around the garden. Sure enough, she found my one butterflyweed plant and proceeded to lay more eggs! Hopefully this outcome will be better. My pipevine out back now has at least 7 Pipevine Swallowtail caterpillars on it. Haven't done a thorough search, so there may be more. Bill Haley Chattanooga, TN
