Still, I don’ know why she lived only about a week.
I have the last group–six chrysalides–ready to eclose in the next day or two. Other birds, rodents, wasps, parasitoids, dragonflies, mantids and even automobiles will kill or injure adult butterflies. Cut back affected areas and discard…don’t compost! Posted: June 15, 2017. A better way of long-term pest management is not to manage them, but to spread out milkweed patches and plant different species of mw….and, of course, bringing in a few to raise indoors. Is that the weevil doing that or just the way the milkweed is growing?

  1. Hi Tony,
    I live the San Francisco Bay Area and have been raising Milkweed for Monarchs for 3 years now. The best sites have exposure to sun or partial shade and almost any soil. Milkweed bugs and milkweed beetle are late season pests. This is a normal part of the milkweed growth cycle.

    • HI,
      the milkweed in my side garden often has aphids and ants on it. if you have room in your garden, plant several species of milkweed and space out your patches so there is room for monarchs, pests, and predators…this creates a healthy ecosystem in your garden, and you won’t have to worry when the ravenous tussocks show up.

  2. Yes can you use floral foam the green kind florist use to soak up water and design flowers in for the varies butterfly weeds instead of tubes? I carried 4 in last night but they are not happy in the glass jar that I put them in. It doesn’t move or have legs. I have to do something but afraid of killing my babes & eggs!! LOL)
    My question has to do with leaf curling/distortion on common m/w. I know they are not the usual aphids, or the milkweed beetles, but they are nasty and look like clusters of small dirt pebbles or caterpillar poop. Armed with this information, you can easily scan this list and narrow down the possible tomato plant disease or pest problem and how to fix it. It is big enough to host a whole crop of caterpillars and the adults love the flowers. The bug does not eat through the leaves, but you can see what looks like a trail going through the leaves. I have been killing them but I want some help in finding out what it is. Do you think I should move them to another plant?

  3. I think I have a moth larvae infestation. Hard to find since they hide during the day and eat at night.

    Typical is to find the top portions of a stem wilted and hanging over. We put up a rabbit fence this season and it made a huge difference…no more rabbits in the back yard garden!

    • WOW okay I do have mice. The pendulum swings back and forth, but an equilibrium is established. ( It was AMAZING! Only my 3rd year in this garden bee balm, black eyed susan, pye eyed joe, mums and a few other things. Butterfly weed is slow to start growth in the spring. They are on almost every leaf.

They are all busy getting on with… This was around July 1st and I hope that he/she went on to become a healthy butterfly. of vectoring plant diseases such as viruses and phytoplasmas. Tony, WHERE do YOU get your plants or bulbs?

      • Hi Mary, I got ours at a plant sale in Minnesota. It didn’t work; apparently, my ants like a jolt of caffeine.

        However, I’ve managed to get the aphid problem under control, which was leading to the ant issue. TIA

        • Hi Nicole, potentially sounds like some type of fungus. More. You might want to try posting a photo of the leaf damage in an insect ID group, where there are help insect experts:
