29th: Cuckoo still calling at Treshnish wood and a Collared Dove calling at Treshnish Old schoolhouse and seen later at the cowbarn (it is obviously just a matter of time before they breed here).

Slow Worm at Treshnish Old Schoolhouse.

A Calgary neighbour told me she saw one at exactly this spot a few days ago and sent Carolyne.

Probable Orange-tailed Mining Bee at Treshnish Old Schoolhouse.

At least 10 Painted Ladies between Treshnish wood and Haunn.

Peacock butterfly larva in our garden.

Broken-belted Bumblebee to northeast of Treshnish Old Schoolhouse. The yellow hairs on the first tergite of the abdomen is diagnostic.

zoomed in

28th: 1 Swift below Treshnish House

and at least 1 Painted Lady along the sea cliffs there.

1 7-spot Ladybird at Treshnish boathouse beach. I think it is my first for Mull!

1 Sea Pea plant at Treshnish boathouse beach (rare on Mull)

along with a Scots Lovage on the beach (usually they are on or near sea rocks).

27th: Whitethroat

At Treshnish wood waterfall: 1 mini-miner, furrow bee as well as 1 small metallic furrow bee, 1 Little Nomad Bee, at least 2 blood bees one of which has bee accepted as Furry-bellied Blood Bee.
At cliffs to south of Ensay Burn mouth at least 2 blood bees, most probably Furry-bellied Blood Bees, 2 Little Nomad Bees. and a Crossocerus solitary wasp at its nest hole. This is not the same species as at west cottage Haunn. It has yellow markings behind the head and on the legs.
The first 2 shots show it bringing a prey item to its burrow. Unfortunately it was in a dark situation and i had the shutter speed top slow and missed a close up flight shot at it left the burrow.

Also at the cliffs top south of Ensay Burn mouth, probable Red-legged Shieldbug Pentatoma rufipes mid instar nymph.

A new micro moth for me near Treshnish wood waterfall, Argyresthia brockeella. It has been recorded on Mull by others.

26th: An adult White-tailed Eagle was seen taking a prey item from the Common Gull colony at Treshnish lochan. Some of the Common Gull chicks took what was thought to be their maiden flights away from the lochan today but in retrospect I think they are last years birds.

This season Herring Gulls have been seen around the lochan and have presumably bred too. 1 Cuckoo at the waterfall.

1 Little Nomad Bee, 1 large nomad bee, and a tiny metallic furrow bee at Treshnish wood waterfall.

1 Little Nomad Bee and a small metallic furrow bee at cliffs to south of Ensay Burn mouth.

1 possible Slender-footed Robberfly Leptarthrus brevirostris at Treshnish wood waterfall

Flowering Coltsfoot at Treshnish Burn cattle-grid. Usually it flowers early in the spring.

25th: 1 adult Peregrine over Treshnish lochan

and 1 Sparrowhawk over Treshnish wood. Both good records for the breeding season. Grey Wagtail family still at Ensay Burn mouth.

1 Northern Emerald to northeast of Treshnish Old Schoolhouse and again 6 hours later. I may have also seen it earlier in the week. This is a rare species on Mull although I saw it for the first time last year on the 3rd June over the hill about a mile to the south.

showing the diagnostic calliper shape

Nearby was a solitary wasp, probably Argogorytes mystaceus, which I have seen twice before.

Finally re-located the Wall Mason Bee at the cliffs to south of Ensay Burn mouth. It was about 20m to north of where I saw it on the 21st May.

Other bees at the cliffs to south of Ensay Burn mouth: 3 blood bees, at least 2 Little Nomad Bees, several small metallic furrow bees. and 1 possible Tormentil Mining Bee.

The face.

At Treshnish wood waterfall: 1 blood bee, furrow bees including 1 small metallic furrow bees.

1 Dark Green Fritillary at Treshnish wood waterfall (my first of the year).

24th: Cuckoo heard around Treshnish wood.

23rd: Cuckoo heard around Treshnish wood. 4 or 5 female/juvenile Goosanders or Red-breasted Mergansers upstream at Ensay Burn mouth. Grey Wagtail family also still present there.

At the cliffs to south of Ensay Burn mouth, an accepted Furry-bellied Blood Bee (a first for Argyll).
Also there were 2 or 3 Little Nomad Bees there also. At first I thought one or two, which was much larger, were Fabricius’ Nomad Bee but after looking at the photographs in detail realised they were all Little Nomad Bees. The book tell same they can vary a lot in size, which explains why the first ones I saw last year appeared so tiny (although Part of that is me getting acclimatised at looking at smaller and smaller insects, e.g. Crossocerus wasps).

One or two (because I saw them at different spots about 20m apart) of the Little Nomad Bees had white spots on the rear of the thorax which made me think I had also found a third species but I think it must be a variation or some sort of anomaly.

Furrow bees, as well as metallic furrow bees and an interesting looking mining bee burrowing a nest hole at cliffs to south of Ensay Burn mouth which could be a Tormentil Mining Bee, with orange hind legs.

Two different small wasps which I think are both Crossocerus species, both of which I think I have seen here on previous visits.
The first is all black on the body and yellow only on the legs

and the other which is yellow and black on the body could be Crossocerus varus. I got better shots than I did on the 28th May.

Several furrow bees entering nest burrows at Treshnish wood waterfall one of which was one of the small metallic furrow bees.

Mining bees and furrow bees at Treshnish Old Schoolhouse and the latter also along the farm-road to the northeast. This mining bee at the schoolhosue had white pollen brushed.

1 Meadow Brown at Treshnish wood waterfall (my first of the year) and 1 Clouded-bordered Brindle in meadow to southeast of Ensay Burn mouth. I have caught this species in my trap at night and also netted it and found it on wine rope trap but to see it in the daytime is impressive.

There are two Guelder-rose trees at the waterfall (not sure if I have seen the second one before or perhaps I have got them mixed up) and the ‘one’ lower down the burn is actually several trees. Now they are flowering they are easier to see.

22nd: Tawny Owl still calling regularly (although not daily) during daytime, always the ooohh call.

What I am pretty sure was a Painted Lady at East cottage, Haunn.

: male Quail still present near gate into Coronation meadow, Haunn.

20th: Possibly 2 calling male Quail at Black Park/Haunn.
The weevil seen on 12th has been identified as Liophloeus tessulatus. It is rare in Scotland and as far as I can see this is the furthest north record.

19th: 1 male Quail heard near the last gate going into Haunn field.
Then I find out Leena heard it on the 17th and Carolyne on the 18th both at the same spot. They didn’t realise what it was.

1 Spotted Flycatcher near Ensay Burn cattle-grid and another at Ensay Burn mouth. This is the first time there has been what looks like 2 pairs at Treshnish. Grey Wagtail family still at Ensay Burn mouth. Heron chick near usual nest being harassed by Common Gulls.


Chaffinch fledgling.

Whilst trying to relocate a Broad-leaved Helleborine below Treshnish wood waterfall found a new non-flowering Narrow-leaved Helleborine.

Also found a Greater Butterfly-orchid in the lower meadow which I think is new.

18th: 1 Spotted Flycatcher near Ensay Burn cattle-grid and Grey Wagtail family still at Ensay Burn mouth.

Blue Tit

: 1 Spotted Flycatcher near Ensay Burn cattle-grid (my first of the year) and Grey Wagtail family still at Ensay Burn mouth.

A couple of hours at the cliffs south of Ensay Burn mouth showed: Gwynne’s Mining Bee, furrow beesmall metallic furrow bee, at least 2 blood bees (one much smaller than the other and so could be 2 species),

2 or 3 of Crossocerus sp, probable spider-hunting wasp, Tree Wasp, Chrysotoxum arcuatum

probable Scaeva pyrastri,

At Treshnish wood waterfall: 1 probable Northern White-tailed Bumblebee

Furrow bees and Ferdinandea cuprea (only my 3rd record).

14th: a sawfly at Treshnish Old Schoolhouse, possibly Strongylogaster multifasciata.

: Went to check the Barn Owl box near Ensay Burn. It had a lot of droppings and at least 5 pellets underneath. That isn’t really proof of much as anything could be using as a perch and coughing up droppings so I went at dusk to see if there was anything more certain. As I arrived I saw a Barn Owl hunting in the open area to the right of the cattle-grid. It landed somewhere, I think in small willow and about 5 or 10 minutes later it was seen hunting in the same area. Then it seemed to land on the willow but after waiting a while it was getting too dark so I gave up.

Wind even stronger today and still from the north.

Male mining bee sheltering from the wind near Nissen hut.

and female possibly Orange-tailed Mining Bee at Treshnish Old Schoolhouse

More than 1 Broken-belted Bumblebees at Treshnish Old Schoolhouse (including yesterday) but photos showing diagnostic features were out of focus shots.

Large sawfly possibly Tenthredo livida near Nissen hut

Bug near Nissen hut

Leucozona lucorum at Treshnish Old Schoolhouse and along farm road to the northeast and northwest of the schoolhouse.
Criorhina berberina of both forms near Treshnish wood Nissen hut.

A weavil between concrete ramp and cattle-grid, hopefully I will be able to id it. It looks like Barynotus obscurus but that species doesn’t occur in Scotland. I know Barynotus squamosus does so it could be that.

11th: Willow Warbler

Fairly strong winds from the north limited bee watching.
Best find today was a new wasp which I think is Nysson spinosus Large-spurred Digger Wasp near the Treshnish wood Nissen hut.

and showing the inner broken yellow band

Also in the same area a probable mini-miner, presumably same as on 4th.

Male mining bee possibly Wilke’s Mining Bee to northeast of Treshnish Old Schoolhouse

Everyday whilst watching bees I see Ancistrocerus oviventris and today was no exception

but today was the first day this year in which I saw Ancistrocerus scoticus at Treshnish Old Schoolhouse.

Pretty sure this is Forest or Red-legged Shieldbug .I have seen adults here before but not nymphs. This mid instar nymph was found to northeast of Treshnish Old Schoolhouse

and this late instar nymph was found near the Nissen hut.

A leafhopper or treehopper

10th: 1 Barn Owl seen again behind Treshnish Old Schoolhouse after midnight (so technically the 11th) adult Peregrine over the Common Gull colony.

Willow Warbler

At cliffs to south of Ensay Burn mouth: Gwynne’s Mining Bee excavating nest burrows

Little Nomad Bee,

small metallic furrow bee, other furrow bees,

Crossocerus sp which I don’t think is the same as that at west cottage (it has some yellow marks behind the head amd more contrasting leg markings – but less than the one seen here last month),

and what I think must be a spider-hunting wasp, (very small and fast!)

Chrysotoxum arcuatum, a new hoverfly which could be Pipiza noctiluca

and Pyrausta cingulata and Common Blue.

Small Pearl-bordered Fritillary along farm road through Treshnish wood

Golden-ringed Dragonfly

9th 1 Barn Owl behind Treshnish Old Schoolhouse at just after midnight (technically the 10th).
Got better shots of the Crossocerus species. There were at least 5 present. The location seems more likely for Crossocerus elongatulus. None photographed today showed the large head and they have a more pointed abdomen so could be males.

Found a small metallic furrow bee at the small quarry by East cottage and a blood bee hunting the same spot.

On the runnel bank to east of Toechtamhor gate found several active furrow bee nest burrows. There were at least 3 female bees.

At same spot sawflies

At our house a wasp which I thought could be a spider-hunting wasp but none fit. I appears to have a waist so I don’t think it is a sawfly

There are a lot of beetles around this year. I can’t keep up with identifying them all when the weather is fine. This pair were in our garden.

8th: At least 2 tiny wasps at west cottage, Haunn. We managed to get a phone shot.
I am pretty sure it is a digger wasp, a Crossocerus species and with the large head it looks like Crossocerus megacephalus but there are 4 all black Crossocerus species found in Scotland although 2 of them are rare. Crossocerus elongatulus is the most common and in 2006 BWARS notes that there was only 1 Crossocerus megacephalus record in Scotland although there are many more recent records (none near Mull).

4th: reports of a calling Corncrake at Haunn
At least 4 Crossbills at my Breeding Bird Survey square at Loch Frisa (my first in BBS).

A few new sites for hoverflies at Loch Frisa: Chrysotoxum arcuatum, Sericomyia silentis, Rhingia campestris, Sphaerophoria sp., poss Xanthandrus comtus
Also there: Small Pearl-bordered Fritillary, Small Heath, Speckled Yellow (a good site for this species), Garden Tiger larva, a flying Cinnabar Moth, poss Cryptic Bumblebee queen, Common Carder Bee, dor beetle prob Anoplotrupes stercorosus and Bracken Chafer and a new bug species for me to identify.

At Treshnish found a new moth, Small Purple-barred behind the Nissen hut in Treshnish wood.

Also many Criorhina berberina of both forms near the Nissen hut and in our garden, previously I had only seen the all orange form and only once, last year (on 20th June).
This is the white-tailed bumblebee mimic

and this is the carder bee mimic

A tiny female mining bee in front of Nissen hut in Treshnish wood, possibly a mini-miner. It flew before I could get closer.

At Treshnish Old Schoolhouse a Fork-jawed/Panzer’s Nomad Bee. The lower photo appears to be showing the bifid mandibles of Fork-jawed Nomad Bee

Also around Treshnish Old Schoolhouse, bees and wasps: female presumed Red-Backed Mining Bee, Orange-tailed Mining Bee, furrow bee and many mining bees, Tree Wasp
Beetles: Red-Breasted Carrion Beetle Oiceoptoma thoracicum, prob Ctenicera cuprea, click beetle poss Dalopius marginatus
Hoveflies: poss Syritta pipiens, Rhingia campestris, Sericomyia lappona, Chrysotoxum arcuatum, an interestingly marked interesting Sphaerophoria sp., Leucozona lucorum

2nd: Leucozona lucorum present at Treshnish Old Schoolhouse.
Bell Heather flowering near Treshnish Old Schoolhouse

1st: 1 House Martin around treshnish farm buildings.

25/5-1/6 Guests in east cottage, Haunn heard Red Grouse above the cottages and a pair of Ringed Plovers at Port Haunn.
