I have been informed that one or more of the Panzer’s Nomad Bees from 27th and 28th May in Black Park quarry is a good candidate for Bilberry Nomad Bee Nomada glabella a new taxon which is probably going to be treated as a full species in the near future (already treated as such in Norway).

Here are all my Keeled Skimmer records. I have sometimes had 5 year gaps in seeing one at Treshnish so that is why I get excited about them plus the male is stunning. The female looks similar to a female Common (Highland) Darter.

18/06/2020 1 female in lower Ensay meadow.
08/06/2020 1 female near the concrete ramp in Treshnish wood
07/08/2018 1 overmature female at Black Park (wee waterfall up hill)
09/07/2013 1 poss same as previous day beside the road in Black Park field nr east gate
08/07/2013 1 immature? beside the road in Black Park field nr nr east gate
04/07/2012 1 male at boggy pools to northwest of Haunn cottages
25/06/2010 1 male at boggy pools to northwest of Haunn cottages
14/06/2010 1 immature(?) On farm road beside Treshnish wood near the old french no hunting sign
21/08/2007 1 male & 1 female possibles at Reudle Schoolhouse bog. No photos.

Elsewhere on Mull:

17/08/2010 3 at Carsaig

30th: Bullfinch heard Treshnish Old Schoolhouse and Cuckoo seen below Ensay farmhouse.

Leucozona laternaria a new hoverfly at Treshnish Old Schoolhouse.

I think this could be Sphegina clunipes

but this is the one i was trying to get a close up of but it was too wary. I think it is Sphegina sibirica.

and 1 male Tormentil Mining Bee (confirmed) in Treshnish Old Schoolhouse garden.

and probable female Tormentil Mining Bee at Treshnish Old Schoolhouse

and 2 and a half hours later the same or another one.}

1 Honeybee on Calgary machair.

Common Blue on Common Spotted-orchid at Calgary machair.

5 Pyramidal Orchids at Calgary machair.

 

29th: Bullfinch heard Treshnish Old Schoolhouse
2 fledged Common Gulls flying over lochan

26th: Long-tailed Tits heard in Treshnish wood.

1 probable male White-jawed Yellow-face Bee (near the Eucalyptus in Treshnish wood)

Loads of Peacock caterpillars on our nettles.

1 Bird’s-nest Orchid found about 5m from the ones found on 20th July 2012 (1 fresh and 2 from previous years).
I have looked every year (which has become almost a pilgrimage) since and although I think there must others in the wood this is my first since 2012.

The Broad-leaved Helleborines in the wood itself are 2 near the lower owl box and 1 at the runnel near the steep cliff. The rock fall at the steep cliff has buried some if not all of the plants there. None of the 3 in the wood have a flowering stalk but of the ones along the farm track 3 have flowering stalks.
The Narrow-leaved Helleborine near the owl box flowered but has no fruits.

At least 4 Thyme Broomrape at their usual site.
Carolyne has been finding Zigzag Clover and after helping her with it I decided to try myself. I had given up several years ago but now I felt more confident about the features. I found several near the Thyme Broomrape cliffs.The colour is strikingly darker than Red Clover.

24th: a new bee, a male White-jawed Yellow-face Bee (confirmed) at Ensay Burn tributary junction, Treshnish wood.
I think there are only half a dozed records for Scotland and none between Loch Lomond and Inverness and only one other record south of Loch Lomond.

and another new bee for Mull, Box-headed Blood Bee (confirmed) at cliff b south of Ensay Burn mouth

1 digger wasp Crossocerus dimidiatus (confirmed) entering a nesting burrow at cliff b south of Ensay Burn mouth (same one I saw on 18th)

also another Crossocerus possibly Crossocerus varus entering a nest burrow at cliff b south of Ensay Burn mouth

and another possibly Crossocerus tarsatus at cliff b south of Ensay Burn mouth.

1st Greyling of year at cliff b south of Ensay Burn mouth

1-3 Little Nomad Bees 1 probable mini-miner, 1 small metallic furrow bee and a large mining bee (poss Chocolate Mining Bee) and 1 Swollen-thighed Blood Bee (confirmed) at Ensay Burn tributary junction in Treshnish wood and 1 Little Nomad Bee, 1 small metallic furrow bee and 1 medium size blood bee at cliff b.south of Ensay Burn mouth.

Xylota jakutorum at Ensay Burn tributary junction in Treshnish wood.

Chrysotoxum bicinctum at Ensay Burn tributary junction in Treshnish wood. I am seeing it more often now but it is a beautiful hoverfly.

1 Narrow-leaved Helleborine at TW waterfall eaten by sheep
1 Broad-leaved Helleborine at concrete ramp has a flowering stalk, so 3 flowering plants close together and 1 at the other site (flowering is rare at Treshnish).

23rd: Cuckoo at Treshnish wood waterfall (there were 3 there).

Grey Wagtail below Treshnish wood waterfall

Spotted Flycatcher below Treshnish wood waterfall. There has always been at least one pair breeding in the wood.

At least 4 Long-tailed Tits near the Eucalyptus in Treshnish wood.

Went to count Helleborines at the nearby site. The top section had 13 Narrow-leaved Helleborines including 1 which had flowered (but no fruit) and 3 Broad-leaved Helleborines including 1 which is going to flower.

20th
: First Meadow Browns in Black Park.

At least 17 Small White Orchids in usual spot in Black Park

1 Moonwort and 1 Frog Orchid near Toechtamhor, Haunn

18th: There is that man again, always around when I want to feed my chicks.

Lots of Dark Green Fritillary around, no Small Pearl-bordered Friltillary.

1 Chrysotoxum arcuatum to northeast of Treshnish Old Schoolhouse.

1 Ferdinandea cuprea at Ensay Burn tributary junction, Treshnish wood.

1 tiny black, shiny but also hairy hoverfly almost certainly a Pipizini at Ensay Burn tributary junction, Treshnish wood. I think it could be a male Trichopsomyia flavitarsis of which I saw a female at the waterfall on the 8th.

1 female Keeled Skimmer in lower Ensay meadow.

1 mini-miner between Eucalyptus and the boggy runnel before cattle-grid and another at Treshnish wood waterfall

1 small metallic bee at Treshnish wood waterfall and another at cliff b south of Ensay Burn mouth

1 probable Tormentil Mining Bee 70m n of TW waterfall.

2-3 Wall Mason Bees at cliff b south of Ensay Burn mouth.

1 Red-backed Mining Bee female (considered correct by expert) at cliff b south of Ensay Burn mouth; a new species for Mull although it has been recorded at Ardnamurchan. Wilke’s which looks similar has not been recorded in Argyll and nearest record is near Loch Tay.


These are my other dates for Wilke’s or Red-backed Mining Bee

2 minutes later another possibly same species.

and 20 minutes later another Crossocerus with prey larger than itself (possibly a grasshopper)

1 furrow bee, probably Smooth-faced Furrow Bee at cliff b south of Ensay Burn mouth.

17th: First Dark Green Fritillary of the year at Treshnish Old Schoolhouse

16th:  1 Dasysyrphus albostriatus between Eucalyptus and cattle-grid Treshnish wood.

1 probable Argogorytes mystaceus Field Digger Wasp between insect hotel and eucalyptus, Treshnish wood, 1 digger wasp Nysson spinosus to northeast of Treshnish Old Schoolhouse.


15th: at least 4 Long-tailed Tits in TW.

Willow Warbler waiting for me to get out of the way.


1 Chrysotoxum bicinctum near Treshnish Old Schoolhouse at exactly same spot as on 11th.

1 digger wasp Nysson spinosus to northeast of Treshnish Old Schoolhouse and at same spot Argogorytes mystaceus Field Digger Wasp.with prey (possibly a grasshopper).



14th
: 1 Sparrowhawk over Treshnish wood and adult feeding fledged Long-tailed Tit. 1 Collared Dove behind Treshnish Old Schoolhouse. Greylag with at least 3 goslings in lower Ensay Burn meadow.

1 digger wasp Nysson spinosus and 2 Argogorytes mystaceus Field Digger Wasps along farm road through Treshnish wood.
at least 3 blood bees (at least 1 was so small it has to be Swollen-thighed Blood Bee dwarf) at Treshnish Wood waterfall but no Little Nomad or Fabricius’s Nomad Bees.

12th: 1 Sparrowhawk over Treshnish Old Schoolhouse.
The Barn Owl box near Ensay Burn was blown off its pole in the winter. I had a look today. It had about 5″ of compacted nest debris and piles of rodent bones. There was also a couple of very worn feathers and half of a white egg. Barn Owl and Tawny Owl can both have white eggs. I would have thought it was too far from the wood for Tawny Owl and (a strip of Hazel nearby) we have seen Barn Owls around this area and one was found dead below the electrical wires several years ago. But we have also seen a Tawny Owl occupying the Barn Owl box in Black park and that is also out in the open.

1 probable digger wasp Nysson spinosus below Concrete ramp in Treshnish wood.

11th: 1 Sparrowhawk heard in Treshnish wood and Tawny Owl heard in daytime.

1 Chrysotoxum bicinctum near Treshnish Old Schoolhouse. My second record, the first being in August last year on over side of burn.

10th: Found a dead Gypsy Cuckoobee on farm road outside Treshnish Old Schoolhouse. My only record was an accepted flight record in Black Park but this one is further confirmation.

8th: 1 Sparrowhawk over Treshnish wood

1 female Keeled Skimmer near the concrete ramp in Treshnish wood.

A new hoverfly for me,  Trichopsomyia flavitarsis (confirmed) at Treshnish wood waterfall.

and possibly same species along farm track through Treshnish wood.

1 probable Microdon mutabalis at Ensay Burn tributary junction in Treshnish wood.

1 male Panzer’s Nomad Bee (confirmed) cliff b south of Ensay Burn mouth.

1 digger wasp Nysson spinosus (confirmed) between concrete ramp and insect hotel in Treshnish wood

another near the Eucalyptus and a possible Argogorytes mystaceus Field Digger Wasp just past the bridge. All within half an hour of each other.

1 Geoffroy’s Blood Bee (confirmed) at Ensay Burn tributary junction in Treshnish wood
1 Swollen-thighed Blood Bee (confirmed) at Treshnish wood waterfall.

7th: Sparrowhawk calling in Treshnish wood.
Found a Beautiful Demoiselle again in Treshnish wood, this time in the runnel on the opposite side of the road to the Eucalyptus and towards the burn.

2-3 Painted Ladies near concrete ramp on road through Treshnish wood.
Looked for the possible Flat-ridged Nomad Bee in Treshnish wood but couldn’t find any nomad bees there.
1 Ashy Mining Bee between Treshnish Old Schoolhouse and concrete ramp on road through Treshnish wood.

The twin Broad-leaved Helleborines below the concrete ramp in Treshnish wood both have a flowering shoot. I think we have only seen it flowering once on Treshnish and that was at the bottom of the wood. Carolyne’s Narrow-leaved Helleborine looks like it is going to have at least one fruit. The one nearest our house got hit by high winds as soon as it flowered and doesn’t look like it has any fruit. The one near the ramp has been badly grazed and is struggling to do anything at all. The new vegetative ones have at least one plant but there may be more amongst the thick grass.

1st: Tawny Owl calling in daytime in Treshnish wood
1 immature male Beautiful Demoiselle in Treshnish wood, to the west of the Eucalyptus. A first for Treshnish although I have seen it once before in our 10x10km square.

1 Golden-ringed Dragonfly near in Treshnish Old Schoolhouse.
3+ Swollen-thighed Blood Bees at Treshnish wood waterfall (1 confirmed). This is only the second record for Scotland, the other being near Edinburgh.

1+ tiny blood bee (probably Geoffroy’s Blood Bee at Treshnish wood waterfall. P.S. Dwarf Swollen-thighed Blood Bee more likely.
Large Nomad Bee at Treshnish wood waterfall, possibly Marsham’s Nomad Bee.
Probably worn female Northern Mining Bee (or Tormentil Mining Bee) Treshnish wood waterfall.
Found an interesting nomad bee on road beside the insect hotel in Treshnish wood. I only got 2 shots. It is either Little, Fabricius’s or Flat-ridged Nomad Bee. To me it looks more like the latter which would be new for Treshnish and a good find but it is a bit early for that species. BWARS has post 1990 record on Mull in 10×10 km sq to north of Salen and NBN has 1 (probably same) near Ledmore, Loch Frisa (Lorn NHG) swept in quarry on 16 Jul 2014.

1 Globeflower at Ensay Burn (Treshnish) bridge
