Search for the “Silver Shade” Eana argentana

Saturday 20th July: 10. 30am – 4pm Glen Tilt, Blair Atholl


The Silver Shade (Eana argentana) is a small silvery day-flying moth that is only known in the UK from Glen Tilt.  It was first discovered in the glen in 1875 and this remains its sole location in the UK.  It was originally thought to be confined to “one small spot” but in 1878 it was said to be “distributed over several miles”.  However, there have been very few sightings since 1940 and it was last seen in 2014. 

The moth has been found on steep south facing grassy slopes.  The caterpillars have never been found in the wild in the UK but are thought to feed on grasses.

The adult moths are on the wing from around mid-July through to about mid-August.

We need you help to help determine the current status of the moth in the Glen. 

We plan to look for the moth on the slopes where it was last recorded and then elsewhere in the glen.  Hopefully attendees will also go on to look for the moth in other parts of Glen Tilt and even adjacent glens. 

Weather permitting moth traps will have been run the night before and these will be opened prior to beginning the search.  All moths caught will be released unharmed.

There will also be a chance to take part in the Big Butterfly Count.

Meeting place and timings

We will meet at the Blair Atholl Visitor Information Centre which is on the Main Road in the centre of the village and immediately to the west of the bridge over the Tilt (Grid reference NN875654) at 10.30am.  If using a sat nav PH18 5SP is the nearest postcode. 

After gathering at the Centre for tea, coffee and hopefully cake there will be a short talk about the moth, its history and requirements before we set off up the glen to the site, in as few cars as possible, to begin the search. We will aim to finish about 4pm.

What’s needed

Plenty of sunshine, packed lunch, stout walking shoes and a good sense of humour!  Midge repellent and/or a midge hood may also be useful, as would a hand lens and butterfly net if you have one, though the latter can be borrowed.


It is not necessary to book – just turn up!  The event is free and everyone is welcome - you do not have to be a member of Butterfly Conservation Scotland.
