On Rosa multiflora, observed separately.
I had originally thought this might be Fenusa julia which iNat does not have.
See https://www.researchgate.net/figure/10-Fenusa-julia-8-9-Mines-in-Rubus-woodsii-10-Prepupa_fig1_317068119 and of particular note, it "is the first record of a leafmining sawfly of Rosa in North America".
Reticulate pattern and globular soredia on lobe margins
On a small type of birch (yellow?).
I want to say Marmara sp., but this seemed to be more of a spiral around the branch, so I am not really sure.
On Eastern Hophornbeam (mines are all from the same tree, with some tree identification photos included)
On Eastern Hophornbeam. These were on the other side of the bridge from the last observation. (a couple different trees)
Small aspen shoots on a fallen section of tree (I think - sure looks like aspen at the top)
I tried to rear this but it got moldy
ID based largely on host. This is definitely White Ash, Green Ash doesn't occur in this part of Nova Scotia (or in much of NS at all)
Small moth (6mm) inside the house.
Based on the tests I have down to date (C-, K+ y-r), I think this is Cladonia subcariosa. To be sure, I am not certain it requires more chem tests like TLC
