: ( You're absolutely correct Daniele, Got so excited at a possible ident that I did'nt notice the lack of hairs/spikes. Thank you
DanielePralong
Viv, on the pics I've seen the Julia Longwing's caterpillars are hairy/spiky. Which website are you referring to? Maybe we're looking at different instars?
KarenSaxton
The passionflower is the food plant(for caterpillars) for longwings like the gulf fritillary, Julia Longwing and other similar species

Here is the Crinum in all it's glory http://www.projectnoah.org/spottings/7508764

Can I ask you both a question please? One of my early spotting was the following http://www.projectnoah.org/spottings/7508756 which has not been identified, Having just checked out a website on Julia Longwing I'm sure these are the caterpillars. Could you please take a look for me and tell me what you think : )
VivBraznell
Why do you specify Passion fruit plants Karen?
KarenSaxton
It isn't really THAT surprising, if you consider how many plants and animals have spread themselves around the world with the help of humans
DanielePralong
You're welcome Karen! The answer to your question is both! From what I've read they come both from local butterflies farms and imported plants, and have now been naturalized in several part of Thailand for a few years.
KarenSaxton
Thank you for the info Daniele, as I was pondering that possibility. Did they come over via butterfly gardens or on passion fruit plants is the next question
VivBraznell
Thanks Daniele! I was'nt 100% certain it was the same butterfly as my previous spotting of last year, I have only ever spotted one butterfly in the garden here.
DanielePralong
Dryas julia is actually now an invasive species in Thailand...
KarenSaxton
My guess is found in a butterfly garden, as this is an American species that is very popular in butterfly exhibits
