To Ollach Lochs

June 6, 2019

South of Healabhal Beag (MacLeod’s Table South) there is a group of three lochs that had not been visited by a recording botanist for over fifty years. The tetrad they lie in had a few post-1999 records from when I dropped into the northern edge from Healabhal Beag in 2015, plus a few more from Nick and others. It now has 147 post-1999 species recorded.

Beinn Bhac-ghlais had the sort of things one might expect: Diphasiastrum alpinum, (Alpine Clubmoss), Salix herbacea (Dwarf Willow), Vaccinium vitis-idaea (Cowberry), etc.

One of the lochs had several of this large Caddis-fly which I fear will have to go unidentified:

and I spotted this micro-moth, the Yellow-Faced Bell (Notocelia cynosbatella) (thanks Keith for ID):

There were Clouded Borders and Chimney Sweepers too.

The area around Orbost turned out to be rather more poorly recorded than I had realised and I added lots of records to adjacent tetrads. Bromus hordeaceus (Soft-brome) is pretty infrequent on Skye and Schedonorus arundinaceus (Tall Fescue) even more so, but both were present along the main track:

When Skye Nature Group was at Uig last week we noted some Alopecurus pratensis (Meadow Foxtail) where the lower part of the inflorescence seemed to be eaten away. There was more like that at Orbost and a similar effect on Anthoxanthum odoratum (Sweet Vernal-grass). I tried to take some photos but they didn’t turn out well enough to share. I am interested to know what causes this, though.

There was also a planted shrub that I haven’t yet managed to identify:

Later: It is a Spiraea, perhaps Spiraea hypericifolia. There is the same thing in Dunvegan Castle grounds and Ingrid has promised to check their records for an ID.

I spotted a fly mine on Atriplex prostrata (Spear-leaved Orache) which Seth tells me is probably Pegomya sp. but one has to rear the fly for a firm ID.

There was also this on Populus tremula (Aspen), which I am hoping will turn out to be caused by an interesting moth:
