Answers To Your Butterfly Questions

Jaret Daniels is one of the butterfly experts at the University of Florida.  He’s the one we’ve helped (along with the Miami Blue Chapter of the North American Butterfly Association (NABA)) on rare butterfly surveys in southern Florida and the upper keys, and who is responsible for some of the photos and the distribution of the educational butterfly plant brochures we’ve been able to share in our booth at art festivals around the state.  I’ve had the chance to ask him some of your burning butterfly questions; here’s what he said.

On The Lifespan Of Monarch Butterflies

Question:
As I’ve mentioned in our booth (and on our website at Life Cycle of Monarch Butterfly), adult monarch butterflies live two to six weeks, but every fourth generation the adult will live six to eight months so they can make the migration.  I’ve also mentioned that we have in south Florida (and the Caribbean) a population of monarchs that doesn’t migrate (see also the Wikipedia article “Monarch butterfly migration”).  So naturally, the big question is “Does the fourth generation of the non-migrating monarchs still live six to eight months?
Answer:
No

On The Range Of Atala Butterflies

Question:
Since their rediscovery in 1979 (see Atala Butterfly) on Key Biscayne, the range of the Atala seems to be slowly expanding northward. Apparently, their traditional range was restricted to Miami-Dade and Monroe Counties (Florida’s southernmost counties)Atala study, but recent sightings have been as far north as Vero Beach on the Atlantic coast and Tampa on the Gulf coast of the peninsulasee map. The range of coontie, the host plant on which the Atala depends, on the other hand, includes most of the Florida peninsulacoontie range, which makes friends in central and northern Florida wonder “Could Atala’s live here?
Answer:
Probably not; the Atalas seem to be less cold-tolerant than the coontie.
(If it were me, I might still be inclined to go for it.)

Well, I hope this helps.  Feel free to comment.

Although I grew up in Garden Grove, California, I have lived here in South Miami longer than I've lived anywhere else in the world. I've been married to my wonderful wife, Nancy, longer than I was ever without her. We were both teachers. Nancy recently retired after 40 years. I have also spent time as an officer in the Coast Guard, a commercial property appraiser, and an electrical engineering student. Now I'm technical support for Bee Happy Graphics. That means I handle this blog, our web page, and all E-mail, I do all post-processing and printing of the images, I cut mats and glass and frames. If you have a technical question, I would be the one trying to answer it.
