Transcript
[music] Hey it's me Destin, welcome back to Smarter Every Day. So we just got off this boat and we're gonna walk for about an hour in the jungle to find a moth pupa. OK Phil just found it.

Questions & Answers
Q: Why does the Urodid Moth pupa hang its cocoon instead of hiding it like other moths?
The Urodid Moth pupa's hanging cocoon strategy is believed to protect it from predators like ants more effectively than hiding in a silken cocoon.
Q: Why do some cocoons have holes in them?
Cocoons with holes have this feature to prevent the accumulation of water during rain, which could potentially drown the pupa. The holes allow the rainwater to pass through, keeping the pupa safe.
Q: Do pupae need air?
Yes, pupae, like any other living animal, need air to breathe. Surrounding the pupa with water, such as filling up the cocoon with rain, can lead to the drowning of the pupa.
Q: How do butterfly farmers sell butterflies?
Butterfly farmers like John typically ship butterflies in containers with padding to ensure their safety during transit. Most of the butterflies are sold to zoos and botanical gardens.
Summary & Key Takeaways
-
Moth pupae, specifically the Urodid Moth, have an interesting cocoon structure where the pupa hangs almost a foot down from a leaf instead of hiding it in a silken cocoon like most moths.
-
The cocoons have holes to allow rainwater to pass through, preventing drowning of the pupa.
-
Butterfly farmers like John ship hundreds of butterflies each week, with different species having different pupal coverings.
