“Fresh Sheet” is our weekly shipment report of pupae on display in the emerging window. Visit Pacific Science Center’s Tropical Butterfly House and meet our newest residents.


  1. Hi, I love seeing the new butterflies. Any chance of adding pictures next to the names?

  2. Hi Anonymous,

    Thank you for your interest. Unfortunately, posting photos of each species we receive every week would be difficult for the volunteer staff member who maintains this site. We do post an image of one of the species from our weekly shipment to accompany the Fresh Sheet list, however.

    Our online Tropical Butterfly House Identification Guide [] shows some of the most popular butterflies we receive. Perhaps that will help.


  3. Hi, I just want to know if this atlas moth will make a cocoon to lay its eggs too? It is because I found an atlas moth that seems like making a cocoon to lay an egg, since it dies after guarding the cocoon for 5 days. It is different from what i knew that cocoon are made for pupa to emerge as a butterfly. I hope you can make this thing clearer.

  4. Hi Mathuselah. I will only comment on what we see here at Pacific Science Center. We do not provide host plants for our butterflies and moths, so egg laying is very much the exception, but Atlas moths will occassionally produce eggs at random, often on smooth materials such as windows or walls.

    In my experience there is no silk or cocoon material involved; the female simply deposits an egg or multiple eggs. She flies away when she is done, rather than guard it.

    While it's possible that her behavior would be different in a natural setting where she had the appropriate plants, to the best of my knowledge neither atlas moths nor any other lepidoptera produce silk as adults.

    I am very curious what behaviour you were observing. It sounds like you've spent time watching these moths and may have picked up some new information about their behavior.
