We all know the story of tent caterpillars and other agricultural significant insects that were introduced into the U.S.
Has there ever been an instance of introduced butterflies anywhere

The Monarch is global now, feeding on invasive milkweeds in many areas.
European skipper is common in Canada and northern US.
Papilio demoleus is common on Hispaniola now - and I'm pretty sure I saw it on Puerto Rico as well.
Polyommatus icarus (Common blue) in northern Michigan and Canada.
Cabbage Butterflies of course....
Lots of species in Hawaii...

Algais io, Pieris rapae, Polyommatus icarus in North America.
Recently, the name Hestina came up. I recalled Hestina assimilis from Tokyo Japan. But I learned then, that this species is introduced and not native.
In the 90s and early 00s, people tracked the spreading of Cacyreus marshalli. A Lycaenidae introduced from Africa to Majorca (Balearic islands) when I remember correctly. They are so widespread now that they will not disappear.
Dryas iulia (updated spelling...) has been introduced to South East Asia.
Half of the butterflies (and even birds) of Hawaii are not native. They have been introduced from various tropical places.

Hawaii of course .
P.rapae O.K. But I know of no other attempt to introduce a beautiful butterfly ?
others mentioned natural movement
With the number of butterfly zoos around ; some escapes must happen , any colonies ??
A few more swallowtail species would be O K with me.

Colias philodice is native to North America. Colias eurytheme is an unknown entity. It is more than likely of European origins and may have in breeding with a North American species. These are only speculation. Only a lengthy DNA testing would solve the puzzle.
However, if the above is true, what are the origins of our western Colias?
What are the origins of the Colias that occur in the Arctic?

When Anglais io isn't beautiful then I don't know.
Dryas iulia supposedly came from butterfly parks.
Papilio (other than Papilio demodocus) are difficult to delocalize because they are often peculiar in what they need and the host plants are missing.

Dryas iulia was first introduced in SE Asia in Phuket, Thailand. It was farmed there for purpose of releasing butterflies during Buddhist ceremonies and weddings. I’m not quite sure why they picked up this species as there are many beautiful butterflies native to Thailand. Perhaps because it’s much different wing shape and orange colour or maybe for its exotic origin. It is now quite common species in Peninsular Thailand and some neighbouring islands.

Sericinus montela was introduced from Korea to Japan in 1970 and has become widespread in Honshu. jshuey said: "Papilio demoleus is common on Hispaniola now - and I'm pretty sure I saw it on Puerto Rico as well." Yes it is on Puerto Rico, also Cuba and probably many other Caribbean islands. Supposedly it escaped from a butterfly farm when it was damaged by a hurricane. In SE Asia P. demoleus malayanus has spread from the Malay Peninsula as far east as the Solomon Islands partly as a result of deforestation and transport of Citrus plants through Indonesia. P. xuthus was introduced to Hawaii long ago, and also is on Palau, apparently also introduced on Citrus plants brought from Japan. Adam.

Euphydryas gillettii was introduced into Colorado by researchers just to see what would happen.
Papilio demoleus has been reported this year from California, not sure if it will survive long term.
Pieris brassicae has been introduced into Chile and South Africa.

Prepona laertes is now established in S Florida. entnemdept.ufl.edu/creatures/bfly/Prepona_laertes.htmWhen you say attempt that implies people would try to do this for the sole benefit of having a beautiful butterfly around. Non-native species should never be intentionally released without extensive and exhaustive research (and permits). And even when that happens there are often unintended negative consequences.

Having lived in South Florida twice. Once Butterfly World opened it's doors in Broward County, they developed and maintained population of various species of Butterflies. These butterflies were from Central and South American. Some "DID" manage escape. Although population never managed to develop while I was living in Coral Springs, Florida. I only saw one individual in the wild. However, the chances of a population developing were minisclue. But when it comes to mother nature, well, one just never knows.

mikeh said "Papilio demoleus has been reported this year from California, not sure if it will survive long term." I wonder how it could have got from the Caribbean islands to California, assuming it came from there rather than as a seperate introduction. If a gravid female is loose in California the species will certainly survive there. Papilio demoleus is capable of handling hot rather arid conditions as well as tropical habitat. As long as there is Citrus present and a supply of nectar it will multiply. Adam.

Adam, can this species diapause through subzero (Celsius) temperatures? How far north do you think it can spread?

Adam:
I do not believe the Florida citrus growers would like another pest to contend with.
While living in Florida I grew citrus tree's in my yard. I grew Oranges, lemons, limes and grapefruit trees. I never found the larva of Papilo cresphontes on any of my trees. However, the larvae were easy to find in the Homestead area. Especially in the abandoned citrus groves west of Homestead.
I also grew Papya Trees.
The Tomatoes they grow in the South Florida soil are tasteless. During a visit to my father-in-law, I brought home several five gallon pails of Kentucky dirt. I grew some tasty tomatoes in that dirt in Florida.

Adam, can this species diapause through subzero (Celsius) temperatures? How far north do you think it can spread? I expect that it is possible that pupae could survive temperatures a bit below freezing, it is found in the Middle East, where I would think it must encounter those sort of temperatures. However, I suspect that it would not survivevery low temperatures. I suspect that the best guide would be that it probably can survive if Citrus can. Adam.
