You can see trapped crane flies 
While that's what the cultivar description says, that's not been my experience with growing both of them, or most red clones for that matter. I can't really tell any of them apart. Red Dragon, Green Dragon, Holland Red and Royal Red all look very, very similar in coloration. In terms of trap size and growth characteristics, Red Dragon, Green Dragon and Holland Red all have long petioles with fairly large traps. If you lined them all up next to one another without labels, I don't think I could tell them apart.i<3carnivores: Red Dragon in good lighting will turn completely turn dark red to a almost black red. Though Green Dragon will always have green on the edges of the mouth/trap. (EC)
