Hi Lorax. No argument over photography here (I didn't think there really was one?) :) Yes, I'm sure there would be merit in tracking the beetles. To give you an idea how little is know in this area, when I asked Marc that given the beetles are scared of daylight, where did they live during the day? and where did the pregnant female go to lay her eggs? he replied 'nobody knows' - so if you're going to attach sensors to them Lorax and track them, you'll most likely be the first to make this discovery? I'd also imagine the 'lifestyle' (by that I crudely mean how far it wanders) of whatever it is that enjoys eating the plants berries (are there several types of animals?) will also have an impact on the distribution of the plants. I've got a feeling all of this could make a lovely project for someone mathematically inclined. I was going to write a little more about my visit to Kew but I got a bit busy here, but it's done now so I'll add it in as the next post.
