Raasay, East of Arnish

It was ten years since I had last checked up on the Allium vineale (Wild Onion) on Sìthean Mòr. It looks much as it did in 1991 when I first found it and it remains the only known location in the vice-county.

Yesterday was a very pleasing day with lots of locally unusual but not rare plants such as Calamagrostis epigejos (Wood Small-reed), Carex otrubae (False Fox-sedge), Carex remota (Remote Sedge) and Vulpia bromoides (Squirreltail Fescue).

The butterflies are really out and about now with lots of Common Blues and Small Pearl-bordered Fritillaries.

There were quite a few moths too

plus other insects that I could identify like Common Green Grasshopper, Common Ground-hopper and Common Earwig. I don’t remember seeing a Ground-hopper on Raasay before but they are well camouflaged and leap quickly if disturbed.

There was a leaf mine on Sonchus asper (Prickly Sow-thistle) that I thought might lead to a useful record

but it turns out that there are two species of the dipteran genus Chromatomyia that might be responsible and the difference is visible only in interior details of the male genitalia so the only way to distinguish them is to rear the adult, hope for a male, and then have the skill and patience to check out the anatomy. Thanks for that, Murdo.
