I have a phasmid vivarium in the class and some of the young phasmids can have their colour changed by eating lichen like the type in the pic below. So I want to do that in my class to show how environments and diet can change a species appearrance Sadly I've looked everywhere and cant find lichen like this
Justin, I havent got much in the garden, I was hoping for a walk on Dartmoor, but I cant leave mum for that long.
Here is a photo of what is in the garden, there will be more next year, doesnt help you now though. If you want this I will send it, but just say if its not good.
Gardening on the wild, windy west side of Dartmoor.
Justin - that's quite fascinating and reminds me of the story of the moth (can't remember the species) that changed from a pale brown to dark brown due to pollution given off from nearby industrial chimneys. It adapted to its environment albeit one created by humans. Am I on the right track?

Yep, I need as many lichen covered branches as possible

That would be great please Bekkie! Always need more!
The smaller pieces with the lichen would be awesome, please Lyn!
Nutcutlet, received the foxglove seeds today- thank you so much
I'll leave the majority until late winter as you say but might sow a test sprinkle now for fun
Good idea Vic.
