Thank you for your question and pictures.
What you have appears to be a green lacewing. Below is a link provided by Colorado State University. Please read it and let us know if you have any additional questions.
Thank you for the follow up.
It is quite common for insects to "re-use" holes or habitats that have been built by other insects.
Green lace pupae can be found located on the underside of leaves or hidden in places on plants.
Adults emerge in 10-14 days. Adults feed on nectar, pollen and honeydew, as well as on small arthropods. The green lace you found could've also been searching for food.
