We have a caterpillar that is going to turn into a cinnabar moth, we already know what bug it is but it just went into a cocoon (yay!). How long will it be in a cocoon?

Dear Seriously bugged,
According to Bug Life: “Caterpillars are feeding from July – early September and are initially pale yellow but soon develop bright yellow and black stripes to deter predators. … The caterpillars overwinter as pupa in a cocoon under the ground. The adult moths emerge around mid May and are on the wing up until early August, during which time males and females will mate and eggs are laid.” If that is accurate, you will not experience eclosion until next spring.
