31st: Willow Warbler heard in Treshnish wood.

Female furrow bee near Treshnish wood Nissen hut, possibly Smooth-faced Furrow Bee

and also in that same small area a male furrow bee which is either Common Furrow Bee or Bloomed Furrow Bee

Myathropa florea on our flowering Parsley (which hoverflies love)

Common Flower Bug Anthocoris nemorum feeding on the aphids on our Broad Beans.

30th: Probable 1-4 male  Smooth-faced Furrow Bee near Treshnish wood Nissen hut.

A female furrow bee, possibly Smooth-faced Furrow Bee near Treshnish wood Nissen hut

And I am pretty sure this is a pair of Smooth-faced Furrow Bees copulating

A tiny male bee near Treshnish wood Nissen hut. It has yellow antennae and a white face (clypeus) including the lowest part above the mandibles (labrum). It doesn’t seem to be one of the small metallic furrow bees. Presumably a furrow bee?

From this angle the thorax looks hairy

Male furrow bee which is probably Common Furrow Bee

First Common Hawker of the year near Treshnish wood Nissen hut, although I had brief fly-bys of what looked like this species in the last couple of days.

Myathropa florea near Treshnish wood Nissen hut

and Volucella bombylans also photographed there.

Sexton beetle, possibly Nicrophorus vespilloides behind the Treshnish wood Nissen hut.

A bug , possibly Lucerne Bug Adelphocoris lineolatus near Treshnish wood Nissen hut

29th: 1 Spotted Flycatcher in Treshnish wood,  1 Whitethroat and a least 3 Painted Ladies at Treshnish Old Schoolhouse and at least 2 more near the concrete ramp.

A day-flying Antler Moth at the concrete ramp in Treshnish wood.

Hoverflies to northeast of the schoolhouse include: Sericomyia silentis, Volucella bombylans, Helophilus hybridus, Eupeodes corollae, Eristalis pertinax, Scaeva pyrastri and an accepted Cheilosia variabilis

and the fly Linnaemya vulpina.

27th: 1 Whitethroat at Haunn
1 Broken-belted Bumblebee collected dead at East cottage, Haunn must have died between 20-27 July

25th: Painted lady at Thyme Broomrape cliff.

Fully grown Northern Eggar larva to northeast of Treshnish Old Schoolhouse.

1 probable male Smooth-faced Furrow Bee at Thyme Broomrape cliff.

1 Helophilus trivittatus at Thyme Broomrape cliff. It was noticeably larger than other Helophilus but the diagnostic feature is the lack of a dark central stripe on the face as well as the more lemony coloured bands.

Also at this same site was a hoverrlfy which is probably a Scaeva pyratsri.

It was exploring and landing on the unopened Knapweed.

Suddenly I saw something abseil onto one of the knapweeds and then disappear

You have to really look to see it.

At same site, what I’m pretty sure is Sicus ferrugineus, a conopidae or Thick-headed Fly, whose larva are parasites of White-tailed Bumblebees.

Another interesting insect there, possibly a robberfly.

A bug , possibly Lucerne Bug Adelphocoris lineolatus above the nearby Butterbur site

Emerald Damselfly at Thyme Broomrape cliff.

12 Field Gentians at Thyme Broomrape cliff and 10 more at path down to cliffs to west of Thyme Broomrape cliff.

5 Thyme Broomrape at usual cliff.

I checked to see if I could find the Broad-leaved Helleborines near the lower conifers and found one in a non-flowering state. No sign of any Bird’s-nest Orchids.

23rd: 1 robberfly  possibly Slender-footed Robberfly Leptarthrus brevirostris at Treshnish wood waterfall.

1 Gwynne’s Mining Bee, at Ensay Burn mouth cliff a

and 1 Volucella bombylans behind the cliff top.

1 Gwynne’s Mining Bee, 2 blood bees, 1 male Common Furrow Bee, 1 mini-miner,

1 Fabricius’ Nomad Bee at Ensay Burn mouth cliff b. I mistakenly identified a large Little Nomad Bee as a Fabricius’ earlier in the month but this is the real thing. It is my latest record and is obviously a second brood. My previous record this year was on the 13th May.

1 possible mini-miner at south end of lower Ensay Burn meadow.

3 Field Gentians at Ensay Burn mouth cliff b (a new site).

19th: Willow Warbler at Ensay Burn cattle-grid and at Old Schoolhouse and Ensay Burn mouth, Whitethroat heard at Ensay Burn mouth.
Long-tailed Tits heard in morning at near Treshnish wood Nissen hut and in evening to northeast of Old Schoolhouse.

Went to try to get better shots of the possible Red-backed Mining Bee at cliffs to south of Ensay Burn mouth but I only had a couple of hours, so no luck.
But I did find what I am pretty sure is Tormentil Mining Bee at cliff b. I haven’t see it since the 7th although I caught a glimpse of what a bee with reddish legs on the 15th. Today I caught it for a minute and got my best shots which I think clinches the id.

An hour later it was seen again entering a nest burrow.

Also at cliff b: 1 Little Nomad Bee a possible blood bee, a male bee with very long antennae (possibly Smooth-faced Furrow Bee) and 1 probable male Common Furrow Bee

Near the Treshnish wood waterfall found a new hoverfly for me, Volucella pellucens. It is one of the most common hoverflies, widespread in the UK and has been seen on Mull. It it is a woodland species. I am also missing some fairly common wetland species.

Also Volucella bombylans at cattlegrid near Treshnish wood Nissen hut and at cliff a to south of Ensay Burn mouth.

At Treshnish Old Schoolhouse the usual Broken-belted Bumblebees.

At least 3 Graylings and 1 Painted Lady at cliif b.

17th: Willow Warbler and Whitethroat heard at Treshnish Old Schoolhouse

16th: Long-tailed Tit family at Ensay Burn mouth on both sides of the burn.

Willow Warbler also there and also near Treshnish Old Schoolhouse.

At least 2 Grey Wagtails at Ensay Burn mouth.

At Treshnish wood waterfall: 1 probable Gwynne’s Mining Bee.

At cliff b to south of Ensay Burn mouth: 1 Little Nomad Bee, 1 blood bee (probably Furry-bellied Blood Bee), 1 small metallic furrow bee (probably White-footed Furrow Bee), 1 mini-miner (probably Impunctate Mini-miner), 1 probable male Common Furrow Bee caught and released (note the differences between yesterday’s small red bee),

Also there, 1 Sphaerophoria species, 1 Common Darter (my first definite of the year), 1 or 2 of the blood bee like sawflies or wasps with long legs and antennae (possibly 2 different species).
This mining bee at Ensay Burn cliff b doesn’t look like anything I have seen before. It has very white facial hairs inside the eyes, orange ‘tail’ and the hind leg hairs are orange (pretty sure that isn’t all pollen). It could just be a very worn Orange-tailed Mining Bee or perhaps a worn Red-backed Mining Bee. I flew from White Heather to White Heather allowing me to re-find it when I lost it at one point.

1 Scots Argus at Treshnish wood waterfall (first of the year although pretty sure saw 1 on 14th here)

15th: 1 probable Impunctate Mini-miner beside Treshnish wood waterfall.

They are pretty small. It is on Tormentil which gives an idea of size. Rather than struggle trying to get close with a macro lens I tried catching it, photographing it and letting it go.

Crossocerus dimidiatus, a digger wasp at Ensay Burn mouth cliff b, a first for Mull.

A bee at cliff b has me confused. I didn’t get close and didn’t see the red abdomen until I saw the photos. I don’t remember the size but compared to the liverwort it looks tiny. There are very few bees with red on the abdomen and a black head and thorax (apart from the blood bees but this isn’t one of them). I don’t think the shape is right for a male Common Furrow Bee (not long enough) and it looks too small for Small Scabious Mining Bee and the thorax and head look too black. The male Little Nomad Bee has red eyes but that is the closest match I can find. I wonder if it could be Flat-ridged Nomad Bee. There is one Mull record from southern end of Loch Frisa in 2014. Update: They are Geoffroy’s Blood Bees.

I explored the next cliffs along which, which I’m calling c and d. I have looked briefly before but it has usually been too windy as they are more exposed. They don’t have as good exposed top turf as cliff b but they have good faces especially lower down. I thought they might be good for Wall Mason Bee, whose nesting cliff has so far alluded me. An hour didn’t produce much but there were a lot of Graylings.

At cliff c there was a blood bee, probably Furry-bellied Blood Bee so obviously there are other bees here.

1 wasp Crossocerus pusillus (accepted) at Ensay Burn, cliff b south of burn mouth.

At cliff d there was what looks like the same fly as on the 7th, Linnaemya vulpina.

14th: 1 Willow Warbler at Treshnish Old Schoolhouse and 1 Spotted Flycatcher at Ensay/Treshnish bridge.
2 Little Nomad Bee or blood bees , 1 White-footed Furrow Bee (accepted) at Treshnish wood waterfall.
At Ensay Burn mouth cliff b: 1-2 blood bees probably Furry-bellied Blood Bee, 1 Little Nomad Bee, 1 Impunctate mini-miner, (accepted), 1 bee mimic hoverfly Volucella bombylans, 1 wasp Crossocerus pusillus (accepted), 1 Grayling (my first of the year) and rove-beetle possibly Platydracus stercorarius.

1 Painted Lady at Ensay Burn cliff a.

At dusk a huge almost all black bumblebee at Treshnish Old Schoolhouse, which could only have been a Red-tailed Bumblebee.

Alder Tongue Gall Taphrina alni a fungal pathogen on Alder fruit at Ensay Burn cattle-grid bridge.

13th: Sedge Warbler singing at Haunn, 1-2 Painted Lady in Black Park

11th: 1 Little Nomad Bee, 1 furrow bee and 1 probable Hawthorn Shieldbug at Treshnish wood waterfall.

1 Leucozona lucorum to northeast of Treshnish Old Schoolhouse.

10th: Sedge Warbler singing at Haunn, Field Gentian 2+ at Toechtamhor gate and 2+ at Haunn at NM33654765

9th: A plucked and largely eaten Common Gull fully grown chick beside Treshnish House. Peregrine or Golden Eagle? I suspect that a Golden Eagle, especially this new pair, would prefer to pluck further from habitation so I favour Peregrine. As an afterthought maybe a Buzzard is more likely. A Buzzard hangs out a lot in this spot and a couple of days ago it was sitting on top of the bird feeders here.

This is the Elecampane found yesterday. Myth has it that it grew from Helen of Troy’s tears, hence the scientific name Inula helenium.

: Sedge Warbler still calling at Treshnish boathouse and Whitethroat and Willow Warbler at Treshnish old Schoolhouse.

Rock Pipit parent

with fledglings at Calgary machair.

1 Honeybee on Calgary machair. I haven’t seen a Honeybee on Mull since a beekeeper kept his bees in Treshnish wood one year.

Volucella bombylans on Calgary machair (only my second record although the first was a mating pair, last year at Haunn).

1 Painted Lady at Treshnish old Schoolhouse and at least 1 on Calgary machair.

Also on Calgary machair: 1 probable Ancistrocerus oviventris (solitary wasp)

and metallic green beetle possibly Cryptocephalus aureolus

Found 5 Pyramidal Orchids at Calgary. There was a twin in the dunes which is most likely the same spot where they were first seen by Jeff Hodgson in 2016. I have looked each year since then but haven’t been able to re-find it. It is outside the 2 year old sheep fence and I have always seen sheep or signs of sheep here on previous visits. One of the orchids today was definitely a new spot and I suspect that at least one other was also a new spot.

The Sea Pea at Treshnish boathouse has been eaten but there is still a leaf below a stone so I have built a little stone house for it

Found a new plant for Treshnish below Treshnish House but my camera battery was dead. It is probably Elecampane Inula helenium, an introduced species to the UK.

7th: 1 Golden Eagle hunting at the Common Gull colony at Treshnish lochan, a family of newly fledged Long-tailed Tits in Treshnish wood beside the burn (eastern side but obviously using both sides). This is the second year with proof of breeding at Treshnish.

Buzzard fledgling

and irate adult

On cliff a to south of Ensay Burn mouth: 1 probable Gwynne’s Mining Bee, 2 Fabricius’ Nomad Bee and 1 blood bee (almost certainly Furry-bellied Blood Bee).

On cliff b to south of Ensay Burn mouth: 1 Wall Mason Bee (again on Bird’s-foot Trefoil),

1 mini-miner, 1 possible Tormentil Mining Bee entering a nest burrow,

I think this is showing the 3 toothed mandible, diagnostic of Tormentil Mining Bee.

Also On cliff b: 1 Fabricius’ Nomad Bee, 1 Little Nomad Bee, 1 small metallic furrow bee and 2 blood bees (almost certainly Furry-bellied Blood Bee) and 1 what I think must be a male Smooth-faced Furrow Bee. I have had accepted females at the waterfall. This is the species which is a host to the Furry-bellied Blood Bee.

Also On cliff b: a bug possibly Capsus ater

and what can only be Common European Earwig Forficula auricularia, although the abdomen  is very red. Eawigs are in a totally different Order from beetles which include the similarly shaped Rove-beetles but they have no pincers.There are only 4 UK earwig species and 2 of them are only found in the south.


At Treshnish wood waterfall: 1 confirmed female Impunctate Mini-miner Andrena subopaca, 1 small metallic furrow bee and 1 Little Nomad Bee.

To northeast of Treshnish Old Schoolhouse: 1 Sericomyia silentis, 1 male mining bee and at least 1 Cryptic Bumblebee queen

and a colourful fly identified as Linnaemya vulpina. There is one previous record for Mull near Craignure.

6th: 1 male Marsh Harrier on hillside above Black Park, which is rare on Mull but unfortunately no camera.
1 Golden Eagle hunting at the Common Gull colony at Treshnish lochan and soon afterwards 2 at Haunn and Cuckoo at Haunn.

3 Crossocerus solitary wasps at west cottage Haunn confirmed as Crossocerus elongatulus.

1 Painted Lady at Treshnish old Schoolhouse

4th: 1 Painted Lady and Cuckoo at Treshnish old Schoolhouse

3rd: to north of Treshnish Old Schoolhouse: at least 1 Broken-belted Bumblebee

and 1 Norwegian Wasp

1 Leucozona lucorum, 1 Sericomyia silentis and 1 Painted Lady.

2nd: young Adder in our kitchen!

1st: 1 Painted Lady at Treshnish old Schoolhouse
