Caterpillars Chrysalis. Within the chrysalis, an inching, cylindrical eating machine remakes itself into a beautiful. In order for the change from a caterpillar to a butterfly to take place within the pupa, the caterpillar begins releasing enzymes that literally digest nearly all of its own body.
Usually available from june thru september, our monarch eggs and/or caterpillars (larvae) are great for home or school rearing projects. Just before they pupate, monarch larvae spin a silk mat from which they hang upside down by their last pair of prolegs. In all caterpillars, this happens inside a protective shell known as a chrysalis, but the specifics differ from species to species.
In regards to your weather and the monarch butterflies, they should be just fine as long as they are allowed to properly hang and dry once they emerge.
Many of the organs are hidden in the caterpillar and they take a new form within the chrysalis. The caterpillars have similar coloring to the monarchs, but they have an extra set of black spikes sticking up and the coloring is brighter as they mature. They look exactly like a monarch on the outside of the wings but are a darker color and their body matches the inside of the wing color. Hanging down from the top of the inset around the windows.
