I monitor activity almost daily. Have found at least 2 doz. larva since June 26 but only 1 chrysalis! Today July 19 I saw 1 instar; yesterday I saw 2 on different plants in about the 4 or 5 instar stage.. Have posted questions about several pictures and would greatly appreciate info on them. I’m often asked if milkweed is invasive. I have not found it to be so. It seems to be a slow growing plant when it gets no watering. My goal is to have several six foot patches close to the winery and larger patches further away so there is “natural habitat” for monarchs. In the six years since I first planted milkweed they have not spread as much as I imagined or hoped for.
