I am on the search to buy larva as well. " Live Monarch" in Florida looks good - good prices (www.livemonarch.com). Too bad I'm in Canada and they don't ship here. I can only find "painted lady" larva - unless I buy the butterflies at $15. each. Wonder what the odds are that I'd have any sucess with them mating and laying eggs?
It should be easier than it is.....One source says less than 1% of the generation survive....it's fairly obvious the good people here increase those odds by a significant amount. I'm ready to help....the stats say I'm not.
