well I hope someone out there will be generous and just trade without it being "all about the money" as money is not everything as they say! There always is a few people out there who may trade just for the fun of it instead of making it a how much money I can make situation!
Even more than the monetary value difference/issue is the availability factor of each. There are not that many H. coronata ooths available for sale or trade, and even less B. mendica ooths available worldwide.... whereas there are tons of P. virescens everywhere usually.
Doubt that will happen , Like what Rebecca said P.virecens has been available for a really long time, and not as rare as Hymenopus coronatus and Blepheropis mendica, i should be attempting to breed hymenopus coronatus in a week if they are fertile, i dont think i would do such a trade.
well if not trading how bout buying them (a few nymphs) but i am sure you will ask for alot for them for being a hard to find species?Since I dont work and times are tight so I dont always got alot of money to be spending on just a hobby so to speak and trading is my other way to try to obtain something I want if I cant pay for it!
