Look what happens when you wait too long to release a flitty giant swallowtail:
Yep, a tail fell off her wing while I kept her captive for video & pix. Didn't notice 'til after her release.
Still, upon release, she flew fast, high and free. I've seen many a swallowtail bfly in nature with missing 'tails', which led me to research the tails' purpose.
After poking through a surfboard site (surfer lingo is fun to read. Check this out -
"The swallow tail allows the tail to be wide but still hold well in the face of the wave. Swallowtails basically handle the same as a squaretail, but they look 'way' more ominous, the first one i saw was on Jeff Crawfords singlefin board in the mid seventies(as he was dropping in on me, the punk!), and I've liked them ever since!
Nothing more serious looking than a double wing swallow with 4 channels, but really they don't do anything a squaretail can't do on a 3-fin with the normal modern tail width(13.5"-14.") Now everybody wants a 'wider thruster' called a Fish, and they just kind of go hand in hand with a swallow/dove tail for appearance sake, anyways!")
Then I made my way to an actual bfly site. Seems the 'tails' are designed to disengage in case birds or lizards grab at them. Much like a lizard tail when your house cat grabs at 'em. Eh, felt a little better about her broken tail. Not much though.
And I really must explain how exciting this emergence was.
She had pupated for WEEKS, thought she'd never come out. Then Mother's Day rolled around, we happened to have mom to our place for the day, and YES, the butterfly emerged!
So, enjoy the following photos, check out the Mom's Day video Butterfly Confessions Also Facebook Page, and know all turned out well. Mom's Day good karma made sure she flew beautifully, even without her little tail.
