I have a big male tern 4"+. He was the first mantis my LFS had ever received (on purpose). They couldn't ID him, but I bought him anyway. He's been in a 20g for about a year. I have searched high and low for other types (that N. wenn or peacocks) at on-line sources and haven't found any, but that makes it all the more spectacular when your LFS finally does get one. So far I have had glaborous and platysome, also purchased from my LFS.
