to know the landEp. 260 : New Year, New Egg CaseI was out for a walk along the Eramosa River in Guelph with a pal on New Years Day, when she lifted a log and showed me some strange white patches along it.

I also wasn’t certain about egg case, but it seemed a likely guess.

to know the landEp. 225 - Walking Stick InsectsLast Thursday a call came over the radio at work. “I just want to let everyone know that there are two Walking Sticks mating on the tent”. I can’t really remember what I was doing with the students at the time, but we all dropped everything and made our way, some faster than others. I had seen a couple of Walking Sticks over the Summer, but realized, while jogging through the forest on my way to see these two going at it, that I knew very little about the life cycles, ecology and overall natural history of this specie...2023-09-1849 min
