The Solomon's Seal Sawfly Phymatocera aterrima has just appeared in my garden where it has trashed the leaves of its food-plant for years without any obvious long-term effects.  It is one of our TRY! targets.  If you find your Solomon's Seal being defoliated over the next few months, look for the voracious larvae on the undersides of the leaves. All records are welcome, but any from the empty spaces especially so.

*** Please look out for the Tree Bumblebee! ***
Tree Bumblebee
B. hypnorum is very obvious just now as the workers have emerged and are very much attracted to Raspberry flowers. Please make an effort to check any clumps of wild Raspberry you see for the very distinctive brown/black/white Tree Bumblebee and make sure you report it to us.  A picture would be useful for confirmation.

Records from the north and west of our area are especially welcome as that is now the advancing front of the spread.  Already it has been seen in Dornoch, on the current northern edge of the range in Britain, and spread through W Ross is very likely this year. You can see the amazing spread of this bee in Scotland in this animated map.

The expansion of Comma Polygonia c-album in Highland this year has been astonishing. The animated map below shows the spread in Highland based on records in the public domain (NBN Atlas, iRecord, HBRG).

If you know of any Walnut trees please check them for the very obvious galls on the leaves caused by the mite Aceria erinea.  NBN Atlas has only 15 records in Scotland, and we have supplie 7 of them, scattered from Lael in the west to Tain in the east.  I have never found Walnut easy to recognise - it is almost easiest from the galls!

Keep a lookout when you are putting stuff in your plastic compost bin for the tiny white moth-flies Psychoda sigma.  These appeared in early March in Strathpeffer in the same bin where they were present in numbers last autumn.  Though only a couple of mm long, they are very easy to spot on the underside of the lid, and a lens will reveal the dark Σ mark across the wings which is characteristic of the species.  Some more pictures are here.  We have only two sites in Highland, the other being Raasay, so they are bound to be more widespread.  The records are not yet on the NBN Atlas, and there is only one other Scottish record near Dumfries which, though unconfirmed, is likely to be correct. ***Update*** Another site is Fort William where it was found this year.

If you find any, remember to report the find to us.
