There is beauty to be found in the changing of the Earth’s seasons, and an inner grace in honouring the cycles of life.

~Jack Cornfield

A recent post discussed the eclosure of several Cecropia Moths that had spent the winter with us as cocoons. There was a mated pair when I found them that morning. I released all but that pair, keeping those two one more night to try to get some eggs, which the female obligingly laid on the inside of the mesh butterfly cage.

Yesterday, the eggs started hatching. Eggs were laid on May 30 and began hatching on June 10.

First instar larvae are gregarious feeders (I have put them on Black Cherry, one of their listed host plants). They are small (~3/8 inch), dark, and covered in black spikes. They will undergo five molts with each stage lasting about a week. So, for the next 4 or 5 weeks, we will be busy feeding some very hungry caterpillars. The changes will be amazing and I’ll be sure to share photos along the way.

    Thank you for the lovely pictures of the Cecropia Moth life cycle!  During my childhood my mother and my grandmother would both get very excited when they spotted a Cecropia.  However, I had never seen the eggs nor the larvae. The Roads End Naturalist brings us all much pleasure.  Thank you again. Nancy McCumber, Durham

      Thanks, Nancy. I’m looking forward to watching these little guys grow.

    Lovely pictures. I have plenty of black cherry on my property if you need any. I would love to find one of those moths. I think I mentioned before that North American Butterfly Association has a project where they are trying to photograph all stages of butterflies on host plants. They post them in their magazine which is quarterly. You have some great photos and great timing to capture eggs to adult. Thanks for all the photos. What do you recommend for mesh type enclosures for butterflies? I typically raise monarchs, spicebush, and pipevine each year. I usually release the caterpillars that overwinter outside. I’ve got a bunch of plastic aquarium containers which are easy to clean but would also like some mesh containers.

      Thanks, Barbara. I really like the Pop-up Rearing and Observation Cages sold by Bioquip (https://www.bioquip.com/search/DispProduct.asp?pid=1466AV), although I see similar cages offered now at various online vendors.

    Beautiful pictures of the Cecropia Moth development. I especially enjoyed the egg hatch pic. I just had a Polyphemus moth emerge from its cocoon today! I’m so happy!

      They are another of my favorites. I especially like their cocoons.

    […] quick update on the Cecropia caterpillars we are raising…you may remember an earlier post where the eggs from a Cecropia Moth began hatching. That was on June 10. We are almost a month out […]
